What is App Development?

App development is a process of making computer programs to perform specific tasks. In this process, developers make apps that work on PCs, cell phones, tablets, and other devices. 

To perform personal assistants, enterprise assistants, and mobile functionality, you need app development. Some apps can be pre-installed during manufacturing, or they can be web-based software.

There are different platforms for developing apps, such as iOS, Android, Windows, etc.
In this app development guide, we will only discuss Apple’s iOS app development. So, be patient until the end of this roadmap.

What is iOS App Development?

Well, what is iOS app development? iOS application development is the process of creating software for Apple hardware. These include iPhone, iPad, Apple Watch, Apple TV, etc.

iOS developers primarily use Swift to build modern iOS applications, while Objective-C is mainly used to maintain and update legacy apps. Then they deploy those applications only in the App Store for users to download. In that case, a developer needs to have a developer ID.

Why need iOS App Development?

The macOS App Store was not very popular in the past. Then, most of the developers focused on writing apps for iOS or iPad OS. Right now, they will have an extensive and easy opportunity to port those apps and deliver them for Mac users.

So, there will be massive work to port those apps from iOS and iPad OS to macOS. Because the architecture is the same, but still, it’s a different screen size. Also, different tools are used to interact, like we use a touchpad or a Mouse instead of our fingers.

Many companies still need native iOS app developers, and that’s a crucial fact. So, there is not a big problem with finding a job as a native iOS app developer if you know something. Have a look at the reasons why you should learn iOS app development.

1. Increasing Demand of iOS App Developers

Since the launch of Apple’s App Store in 2008, the iOS ecosystem has grown rapidly, creating millions of jobs worldwide. As more businesses adopt mobile-first strategies and invest in AI, automation, and secure digital experiences, the demand for skilled iOS app developers continues to increase.

With the expanding use of Apple devices and new platforms like visionOS, iOS app development remains a strong and future-ready career path.

2. iOS App Development is the Future

Apple Inc. is producing budget iPhones and other devices, especially ARM-based gadgets, every year. And more developers are getting into the iOS ecosystem. In simple words, the Future of iOS app developers is brighter than we can assume.

iOS app development covers both the creative and technical aspects. As a result, it becomes the ultimate beauty among software development services. It means that if you are an iOS developer, you are most likely to work on both coding and designing. And iOS development allows you to do both seamlessly.

Besides, iOS software developers get a higher salary than other platforms. According to Glassdoor, iOS developers get the highest salary in the world. And the average starting salary for an iOS Developer is $131,000/year!

So, if you’re looking to earn money through in-app purchases, iOS app development is the best option to go for. Reference: Average iOS App Developer Salary

3. The Programming Language is Easier to Learn

Once, Objective-C was the most popular programming language for iOS app development. Then Swift came into play and replaced Objective-C in 2014. It had been the industry standard up until then. From the beginning, most iOS developers quickly adopted this platform for coding.

Swift is a powerful and more accessible programming language platform for iOS development. Anyone who knows a little about app development can adapt to this software on their first try. This software also has educational purposes for beginners.

Developers get the most advantages as Swift reduces the learning curve for real. So, it helps you to focus on the idea you’re working on.

4. More Sophisticated Tools

IDE or Integrated Development Environment is Apple’s world-class tool. It makes iOS development super easy for the developers. Besides, it’s easy to use and stable.

Apple’s products, like the iPhone or MacBook, are designed for these tools to make your job easy. 

Again, Xcode is for designing and developing your iOS application. It has been around for more than decade, and its maturation is higher than on Android platforms.

Developers use this software from building to launching the App. Xcode also comes with all of the tools you need in an all-in-one software.

Step-by-Step Process of iOS App Development

iOS app developers focus on quality and security the most. Like other platforms, the first step of ​​iOS app development is research and planning. And after making a perfect plan, the designers start developing mockups and wireframes. 

But iOS app development is not as easy as it seems. Since the developers have to follow many rules set by Apple, the process can be tricky.

Most of the iOS development company tries to ensure a secure user experience. Therefore, they need to apply all the best practices to deliver a great app.

And in this step-by-step guide, we’re going to discuss all the necessary processes and tech stacks to make it easy. By following this guide carefully, you’ll be able to understand the process and even build an iOS app on your own.

1. The Beginning Stage or Planning Stage
2. Development Stage
3. Front End Development
4. Back End Development
5. Perform Testing
6. Deployment Stage
7. Publishing the App to the App Store
8. Supporting Stage

1. The Beginning Stage or Planning Stage

The beginning stage of iOS software development includes four important steps. These steps need to be completed carefully and in sequence before moving on to the development stage.

At this stage, you will perform several essential tasks, starting from analyzing the basic requirements to creating an initial design for the app. This may sound overwhelming at first, but the process becomes much easier when broken down into clear steps.

The first and most important task is to analyze the basic requirements of your iOS application. This step helps you understand what you are building, why you are building it, and what is needed before starting development. Let’s go through these steps one by one.

1.1. Analyze the Basic Requirements

There are millions of iOS applications competing with each other on the App Store. So, in this competitive platform, you must ensure that your App gets downloaded many times. That’s why you must conduct market research to see what apps are already out there.

You should analyze existing apps, understand what problems they solve, and observe which types of apps receive more attention from Apple users. Before writing a single line of code, you must clearly define the basic requirements of your iOS application. Below are the most essential requirements you need to get started with iOS app development.

You will need-

• Apple computer with the latest version of macOS.
• Xcode, Apple’s official integrated development environment (IDE) for macOS, which you can download for free from the Mac App Store.
• An Apple Developer account. You can start with a free account for learning and testing on the simulator, but to publish apps on the App Store and test on real devices, you will need a paid account with an annual subscription fee of $99.

1.2. Build the Right Team

Usually, for developing an iOS app, you need a skilled team of 5-6 people. They must have specific skills for app development. Categorize their positions, responsibilities, and qualities. Different app development platforms need different skills.

To develop an iOS app, you typically need a project manager, one or two designers, iOS developers, and QA specialists to ensure quality and performance.

Before selecting iOS developers, make sure that they have the following skills:

• Strong knowledge of Swift, which is the primary programming language for iOS development, along with familiarity with Objective-C for maintaining older codebases.
• Basic to advanced understanding of the Xcode IDE, which is the main development environment for building iOS, iPadOS, and other Apple platform apps.
• A clear understanding of iOS versions, device compatibility, and Apple’s development guidelines.

The team structure needs to consist of the following experts to develop an iOS application.

• App strategist who defines goals and aligns the app with business needs.
• Visual designer, responsible for UI and overall visual appeal.
• An app navigation planner who designs user flow and interaction patterns.
• Content planner, who structures and manages in-app content.

1.3. Prepare Technical Documents

The development team will need a technical design document (TDD). It is necessary for coordination with the marketing team. Many call it a Software Design Document or SDD. In this document, make sure you have prepared the following features. The information you will need to include in technical documents is:

• How will the general user interface look in the App?
• What would the screen layout look like?
• The places for the buttons
• The color palette
• What will be the Input/output data structure
• The types of data units 
• What are the limitations
• The OOP specs
• The function methods, attributes, and dependencies
• The system architecture

Examples of Technical Documents for iOS App Development:

• Software Design Document (SDD): Describes the overall architecture of the app, including modules, components, data flow, and system interactions.

• Technical Design Document (TDD): Details how specific features will be implemented, covering logic, APIs, frameworks, dependencies, and technical constraints.

• UI/UX Specification Document: Defines screen layouts, navigation flow, design rules, colors, typography, and interaction behavior for consistency across the app.

• API Documentation: Explains how the iOS app communicates with backend services, including endpoints, request/response formats, authentication methods, and error handling.

• Data Model Documentation: Outlines data structures, database schemas, object models, and relationships used within the app.

• Architecture Diagram: Visually represents the app’s structure (for example, MVVM layers, services, repositories, and data sources).

• Testing & QA Documentation: Includes test cases, testing scenarios, device coverage, and acceptance criteria to ensure app quality and stability.

• Deployment & Configuration Document: Covers build settings, environment variables, App Store configuration, certificates, and provisioning profiles.

1.4. Create a Basic Design

It is the stage before you go to the main development stage. Here, use all the necessary information from the planning stage and create a basic design of the App. For example, it could be a draft of the application. 

During this phase, the design team focuses on creating the user interface (UI) and user experience (UX), including the visual elements and navigation flow. Once the initial design is ready, it is shared with the development team. At this point, designers and developers work together to refine wireframes, mockups, and the overall user interface.

The wireframe is the blueprint of your application. Here, you will need to visualize the App’s appearance by sketching the whole idea. You also make it clear in the wireframe how the App will function. 

2. Development Stage

The initial process of iOS development helps to get all the basic requirements. Then, after having the design ready, developers go for the development stage. And it is the most critical phase in the whole process.

In this stage, app developers work hard to bring the App to life. They have to work with three different but crucial developments. The first one is the back end, then the API, and finally the application’s front-end development. 

These components work together to ensure the app functions smoothly, securely, and efficiently. The backend manages data and business logic, APIs handle communication between systems, and the front-end delivers the user experience. We will discuss these development areas in detail later. Before that, let’s look at the development methodologies and platforms commonly used in iOS app development.

2.1. Use Relevant Methodology

Relevant methodologies refer to the systematic approaches you should follow during app development. These methods help answer important questions such as what needs to be built, why it is needed, when each task should be completed, and how the work should be executed.

At this point, you might wonder, “Why can’t I just start writing the app? Why do I need to follow a structured process?” This is a common question, especially for beginners.

App development is complex and involves multiple moving parts. Following a well-defined methodology helps manage this complexity by improving efficiency, reducing errors, and ensuring the app meets functional and quality standards.

You will gain the following achievements if you follow the correct methodologies.

• Repeatability is a process that works like a cooking recipe. By reaping the same process, you will get better predictions.
• By doing standardization, you can ensure the high quality of the App. 
• Making Continuous updates and improvements will benefit you to make a great app.
• Arrange training for the new developers for better maintenance of the App. 
• Traceability is important. So, record every step of the process to know the source of each software artifact.

2.2. iOS Development Platforms

The primary and mandatory integrated development environment (IDE) for iOS app development is Xcode. Apple provides this official platform to build, test, and publish native iOS applications. All apps submitted to the App Store must be built using Xcode.

Using Xcode, developers write code primarily in Swift and design user interfaces using modern frameworks such as SwiftUI (recommended for new apps) and UIKit (for legacy or specialized use cases). Xcode also includes simulators, debugging tools, performance analyzers, and access to Apple’s iOS SDKs, making it the core platform for iOS development.

Apart from Xcode, experienced developers may use additional platforms depending on project goals, such as faster prototyping, cross-platform development, or game creation. However, these platforms are usually complementary and not a replacement for native iOS development.

We have listed the top iOS development platforms here. Have a look at those.

• React Native – A popular cross-platform framework that allows developers to build iOS and Android apps using JavaScript and React while sharing a large portion of the codebase.
• Flutter – A Google-backed UI framework that enables fast development of visually rich iOS apps from a single Dart codebase, commonly used for cross-platform applications.
• Kotlin Multiplatform – A modern approach that allows sharing business logic across platforms while keeping native iOS UI, often used in large-scale or enterprise projects.
• .NET MAUI – The successor to Xamarin, enabling developers to build cross-platform iOS apps using C# and a single shared codebase.
• Unity – A widely used game development engine for building high-performance iOS games, especially for 2D and 3D experiences.

However, native iOS development using Xcode and Swift remains the preferred choice for apps that require maximum performance, security, and access to Apple’s latest features.

3. Front End Development

It is one of the secrets of iOS development. Of course, most apps integrate a web API, but you can make it prettier by adding a few iOS native capabilities. Which is also known as the development of the device-end. But generally, Front-end development is client-side or client-server development.

When iOS apps communicate with a server for data storage, it would be a front-end. But an iOS device can also serve as a host for all kinds of devices. 

For example, your remote-controlled lights and coffeemaker. There’s the situation where your coffeemaker connects to your iPhone. And your iPhone connects to a server. On that server, there’s a calendar that determines when you want your coffee from the machine. So then the App is both back-end and front-end. Thus, it can be either or both or none at all.

Finally, it can be said that it depends on your project. In many cases, it will be front-end. Except, the terms front or back end are related to web development, and your App must be browser-based. In most cases, they are not.

It is tough to say it’s front-end since it doesn’t use HTML. You can still call it a front-end, though. In general, call it iOS development.

4. Back End Development

Many say that iOS developers are afraid of server-side coding. As an iOS developer, you should learn how to write server-side code. Also, don’t be afraid of it. Be open-minded and try to learn new frameworks like Node.js or .NET Core.

In practice, backend systems can be built using various frameworks and technologies, including Node.js, Ruby on Rails, or .NET Web APIs. The choice depends on project requirements, team expertise, and scalability needs.

4.1. Firebase

When we talk about web development, we’re talking about apps that we’ll be communicating with a particular server. And this is what people replace with either Firebase or with some other service.

Firebase provides ready-to-use services like authentication, real-time databases, cloud storage, analytics, and push notifications. It is especially popular for startups and small teams because it reduces backend development time and simplifies infrastructure management.

4.2. Xcode, Swift & Objective-C

If you are fluent in Xcode, Swift, and Objective-C, try to target this part and learn about server-side implementation. You should always consider creating your server and learn server-side skills. 

Now, the question is, where should you start learning the server-side framework? You can use .NET Core, and inside .NET Core, there’s also Web API.  If you’re doing iOS development on a Mac, it might be a little bit weird to use these things.

4.3. Node or JavaScript

The quickest way to start learning about server-side development is with Express. It is a JavaScript framework built on top of Node.js.

Another framework is called Vapor. Again, it is an exciting framework, and it’s changing.

When you are using server-side frameworks, you want to use something more mature. It will be close to the Node or JavaScript community, too.

So, whenever you choose frameworks for server-side development, look for the more mature framework. And look for the framework that has been around for a long time.

5. Perform Testing

You will need to test your iOS app before you publish it. iOS is an Apple-owned platform and runs only on Apple devices. That’s why you will need to test it on several generations of iOS operating systems.

But testing the App in Xcode itself will be the first step. Xcode features automated UI testing for the standard unit tests. Write a test that can navigate through the UI. So the users can find different issues when interacting with the App.

The UI testing requires real user interaction with the App. However, you’ll also want to let humans beta test your software.

Use the TestFlight App before submitting your App to the app store. Apple will make it easy for your friends, family, or the user base to preview your App when you do that. In addition, with TestFlight, developers and members can perform internal testing.

Then, divide your external testers into custom groups. And provide specific builds to them. This way, users can submit feedback about any issues they encounter.

6. Deployment Stage

After working for days, weeks, and months to develop your App, now it’s finally time to set it free. So, once you’re done with iOS app development and testing, submit the App to the App Store.

Xcode will allow you to submit and sign the App. But then you will face a lengthy process of submission. 

Be patient until it finishes the review process. The app store will need many iterations of rejection-revision-resubmission-rejection. After completing all the processes, it will finally approve the App. 

Keep in mind that you will need to pass all the approvals. Then, when your App is on air, build the App Store page by using a program called App Store Connect. Then push it to the App Store. 

Apple charges a commission of 15% to 30% on app sales and in-app purchases, depending on the developer’s program and revenue level. Besides, they will charge a $99 (Ninety-nine dollars) annual fee to participate in the Developer Program.

To publish apps to the App Store, you need to be in Apple’s developer program. But remember, if you do not renew your membership, Apple will remove your apps from the App Store.

7. Publishing the App to the App Store

So, finally, you are about to launch your App. But there are still a few things you may want to double-check first.

Every iOS app developer must follow the app store guidelines. Make sure that you are following all the rules set by the app store. 

The next thing is the app certification process. Don’t worry; it’s just an essential process that you must follow. Here, we posted a screenshot of the documents and the link where you will find them. Read all the instructions carefully, then publish your App.

8. IOS App Development: Supporting Stage

During the support stage, the first issues come with bugs and teething. Though you have performed many tests before, something unexpected can occur. So, you need to fix these issues in the supporting stage.

Every year, Apple announces a new device and updates the OS as well. And when the significant devices come, provide updates in your App to support the new devices. 

In the maintenance stage, you can do all the work step by step. Here, follow the steps that we have mentioned below.

• Monitor servers continuously
• Allocate a team for bug fixing
• Provide general support

iOS App Development for Various Apple Devices

From the beginning, Apple has been creating more unique devices than any other brand in the world. It means that these devices are still gaining popularity and dominating the tech industry.

iOS App Development Technologies

iOS app development tech stacks are tools and languages to develop apps for iPhone, iPad, or Mac. Each tool has a unique purpose in the development of iOS applications.

The tasks include wireframing to designing, and testing the App. Xcode is very popular as it is the only integrated development environment (IDE) by Apple. Let’s learn about more tools besides Xcode for iOS app development.

iOS App Development Frameworks

A mobile application framework, also known as a software framework. These frameworks allow developers to make apps using several sub-components. These include toolsets, code libraries, interfaces, and debuggers.

Frameworks are the starting base of any apps or software. But choosing the proper iOS framework is essential.

So, to make it easier for you, we have rounded up the best iOS development frameworks here. Let’s have a look below.

Core Apple iOS Frameworks

• SwiftUI: Apple’s modern UI framework for building iOS interfaces declaratively. It is now the preferred choice for new iOS apps.

iOS Development Languages

iOS developers mainly work with two programming languages: Objective-C and Swift. Objective-C was the original language used for iOS development and is still found in many older applications. However, Swift has gradually become the preferred language for building modern iOS apps.

Swift is Apple’s primary programming language for iOS development today. It is designed to be easier to read, safer to use, and more efficient than Objective-C. Because of this, most new iOS applications are now built using Swift, while Objective-C is mainly used for maintaining legacy codebases.

As Apple’s modern programming language, Swift is widely adopted by developers and strongly supported by Apple. It offers better performance, improved security, and cleaner syntax. These advantages make Swift more concise, sustainable, and safer for modern Apple devices.

Modern Swift Tooling for iOS Development:

• SwiftUI: SwiftUI is Apple’s modern framework for building user interfaces. It uses a declarative approach, which reduces code and makes UI updates easier.
• Async/Await: Async/await simplifies asynchronous tasks such as network calls by making the code more readable and easier to manage.
• Combine: Combine is used for handling asynchronous data streams and managing state, especially in SwiftUI-based apps.
• Swift Package Manager: Swift Package Manager helps developers manage third-party libraries directly within Xcode.

For most new iOS apps in 2026, Apple recommends using Swift’s async/await for networking and background tasks, with Combine used selectively for reactive pipelines or complex state management.

ORMs and Database

A database is a structured way of storing and managing data. Almost every digital application uses a database to store information such as user data, settings, and app content. Mobile apps also rely heavily on databases to function properly.

ORMs (Object-Relational Mapping) help developers work with databases using programming objects instead of writing raw SQL queries. In iOS application development, ORMs and database frameworks allow developers to create, read, update, and delete data more easily and safely.

For example, the contacts stored on your phone are managed through a local database. Similarly, iOS apps use databases to store offline data, user preferences, and cached information.

Below are some commonly used ORM and database solutions for iOS application development.

• SwiftData – Apple’s modern persistence framework designed for SwiftUI
• Core Data – Mature and powerful solution for complex data models
• SQLite – Low-level storage for full control
• Realm – Third-party mobile database for cross-platform use

For new iOS apps in 2026, Apple recommends starting with SwiftData or Core Data, especially when building apps with SwiftUI.

Development of APIs and Libraries

Apple provides many developer resources for iOS app development. When you develop the API, there will be an extensive collection of resources available to you. 

Apple also has native APIs and libraries, and their kits are stable, feature-rich, and easy to use. So, to integrate your API into Apple’s existing infrastructure, you can use these iOS SDKs. 

For game development, you will have SDKs like-

• SpriteKit
• GameplayKit
• And ReplayKit

Besides, Apple has API SDKs for health apps, maps, cameras, as well as Siri. Siri is Apple’s virtual assistant. An excellent AI feature that is very popular among iPhone users.

By utilizing these great tools from Apple, you can benefit your iOS development. Again, the integrated third-party apps will allow you to create apps that connect to social media, use the camera or native calendar app, and more.

Expanding Into the Cloud

Apple’s devices are powerful at handling loads. But you should be careful about the heavy lifting to the cloud. When you connect your App to the cloud, you can take the storage advantage from the cloud. 

There, you will also get facilities like database management and even App caching. Moreover, with the help of next-generation services, you can also augment your App. 

To develop web apps and iOS back ends, you use Kitura and REST APIs within the iOS App. If you carefully look at the image below, you will find the proper direction to expand your App into the cloud.

Best Practices in iOS App Development

If you don’t want to fall behind, you should follow some best practices during development. The best practice helps you improve your learning curves.

Otherwise, you may make many mistakes that will ultimately make you fall behind. Applying the best practices will help you avoid most of your mistakes. So, let’s discuss some best practices that you should follow in your iOS app development.

Proper Documentation is the Key

You will need to make easy documentation that covers all the necessary aspects of the system. The project goals, descriptions, and outcomes all need to be described in detail to keep you on the right track.

Follow the App Store Rules

Always follow the rules from the app store. Because if you don’t, you will face many issues after submitting the App to the app store. 

Getting your App published may seem simple, but you can’t imagine how tough it could be. At the planning stage, you should think of it. Then you can approach the development process. So, make sure you have read all the guidelines from the app store to save time and avoid issues.

Focus on Security from the Beginning

Apple devices and software are considered the most powerful among all the available technologies. But, without enough security, the app store may not allow your App to publish. So, you must focus on security from the beginning.

Access to data stored on mobile devices is a significant security issue. So, make sure you do not keep a chance for the scammers to steal data through your App. 

Start with Minimum Viable Product

MVPs or the minimum viable products, are crucial for an app. No developer can overestimate the MVP features. So, focus on the essential features that will benefit your App in many ways. You will get feedback sooner if you add MVPs. Increasing user satisfaction will be more accessible by using MVPs.

Aim for Great designs

Apple is famous because it has excellent, minimalistic designs. Clients who buy iPhones, iPads, or Macs think about the design first.

As Apple provides User Interface guidelines, it will be easy to develop a great design. In addition, it can be your first place where you can get ideas about iOS app interface design.

Do Not Compromise with Accessibility

You should think about the people who are struggling with disabilities. Follow the accessibility principles. It will make you design better applications and help different users.

iOS App Development Cost

On average, iOS app development costs range from $40,000 to $500,000 or more. However, this is not a fixed price. The actual investment depends on several factors such as app complexity, feature requirements, technology stack, and development approach. In simple terms, building an iOS app is similar to building a house the larger and more complex it is, the higher the cost.

Several factors influence the overall iOS application development budget, and understanding them helps you plan better.

• The size of the app plays a major role in determining cost. Larger apps usually include more features, screens, and integrations, which increases development time and expenses.
• The complexity of features also affects pricing. Simple features cost less, while advanced functionalities such as real-time tracking, AI-based recommendations, or custom animations increase development effort and cost.
• UI/UX design costs vary depending on the level of customization. Apps with basic layouts require fewer design hours, while highly interactive and visually rich designs take more time and resources.
• The development approach—native or cross-platform—also impacts cost. Native iOS apps are built specifically for Apple devices, while cross-platform apps are developed for both iOS and Android. Cross-platform development can increase the overall budget due to additional testing, optimization, and deployment efforts across platforms.
• App testing is another important cost factor. Proper testing ensures performance, security, and reliability. Different testing types, such as functional testing, performance testing, and device compatibility testing, contribute to the total development cost.

Below is an estimated cost breakdown based on app complexity.

App Type	Price Range	Description
Simple Apps (MVP)	$40,000 – $90,000	Basic utility apps, static content apps, or informational applications.
Medium Complexity Apps	$90,000 – $150,000	E-commerce apps, booking systems, or social apps with standard features and backend support.
Complex Apps	$150,000 – $300,000+	On-demand service apps, advanced gaming apps, or business applications with custom integrations.
Highly Complex / Enterprise Apps	$300,000 – $500,000+	Large-scale enterprise solutions with advanced features, integrations, and high scalability requirements.

To get a rough estimate of the cost required to develop an iOS app, you can think in terms of development hours multiplied by the hourly rate of your development team, adjusted for design, testing, and ongoing maintenance.

Total Development Hours × Hourly Rate of Developers = Total iOS App Development Cost

This basic formula helps you estimate the overall cost of iOS application development. First, calculate the total number of hours required to design, develop, test, and deploy the app. Then, multiply those hours by the hourly rate of your development team.

For example, if your iOS app requires 1,200 development hours and the developers charge $40 per hour, the total development cost would be:

1,200 × $40 = $48,000

This formula gives a rough estimate. The final cost may increase based on additional factors such as UI/UX design complexity, backend development, third-party integrations, testing, and ongoing maintenance.
