This is a clear reflection of how the mobile app industry is growing, hinting at the larger business opportunities.  

When it comes to mobile app development, Android and iOS are the two most popular platforms. While both are popular for their own specific reasons, one thing that is common between the users of both the platforms is their expectation for a great user experience.   

In our iOS app development guide, we will focus on Apple’s iOS technology and give you answers for all your business queries related to the technology. Read on!  

What is iOS App Development?

iOS is Apple’s mobile operating system (OS) that runs on hardware including iPhone, iPad and iPod Touch. An iOS application is programmed in languages such as Swift and Objective-C and then deployed to the App Store for users to download.   

Why Choose iOS for Mobile App Development?

As in January 2022, iOS is not the leading OS platform in the world. The first place belongs to Android with a close to 70% market share with iOS holding the second place at roughly 25%, as per Statista

Despite being the second most popular mobile app platform, Apple’s iOS remains one of the most successful operating systems among its competitors worldwide. Here are the various reasons why you should consider developing apps for iPhone and other devices for your business. 

Powerful platform

iOS is a powerful platform that helps you build user-friendly applications. The platform offers great user experience and provides well coded apps for users. The devices are always in sync with each other and there are no compatibility issues.   

Great app speed and reliability

The iOS platform provides applications that are easy to use and have good speed, thus enhancing the user experience. Whether you have a small or large customer base, the iPhone users can have the experience of a small yet feature-rich app.    

Larger user base in the US

As reported by Statista in June 2021, iOS accounted for over 50% of the mobile OS market in North America and Android accounted for about 46% of the market. As per another report released by the same firm in March 2021, nearly 300 million people in the United States use a smartphone out of which over 113 million people use an iPhone, accounting for about 47 percent of all smartphone users in the United States.

Loyal users

Due to Apple’s goodwill and reputation in the market, the iOS platform has its own set of loyalists that choose the iOS app without any second thoughts. As reported by Statista, in a 2018 smartphone survey, over 40 percent of adult Americans bought an iPhone based on their loyalty to Apple.  

Apple users have a higher buying capacity

iPhone and iPad users tend to have higher incomes and spend more on technology as compared to Android users. This can impact actions such as in-app purchases and paid subscriptions, which play a huge role for a business model that depends on such user behavior. 

Apple users use the latest version

The majority of the Apple users run their device on the latest version, which makes programming and development easier as you can have a fair idea of what your app will be able to deliver. 

As per Apple, 72% of all devices introduced in the last four years use iOS 15 on iPhones. 


Also, 57% of all devices introduced in the last four years use iPadOS 15.


Types of iOS App Development

iOS development can be done for native apps as well as hybrid apps

Native iOS apps are the ones built specifically for the platform using iOS app development languages and tools such as Swift, Objective-C and Xcode. Unlike other web applications, a native iOS app does not run in the browser. You can only download the app from the Apple’s App Store.

Hybrid apps are a blend of native and web solutions. Here, the code of the application is written using languages such as CSS, HTML and Javascript. Once written, the app is then encapsulated within a native app. A hybrid app can be used on multiple platforms including both iOS and Android.     

iOS App Development Languages

Once the reservations regarding how and why iOS can be helpful in your business, the next question that arises is which iOS and iPhone app development language is best for the purpose. Here is a list of some of the best iOS programming languages for both native and hybrid app development.


iOS app development in Swift language is one of the most popular choices among businesses. It is used for building native iOS apps, is concise and has easy to use syntax. It is designed to work with frameworks such as Cocoa, Cocoa Touch and the extensive codebase written in Objective-C for Apple products. 

If you wish to develop a quick application that can be expanded later, iPhone app development in Swift language is a good choice.  



Objective-C is created as an extension of the C programming language. It is one of the oldest languages developed in the early 1980s by Tom Love and Brad Cox. It is a general-purpose language used for programming for Apple’s operating systems such as OS X and iOS and their APIs – Cocoa and Cocoa Touch. 

If you wish to create an app that is compatible with the older versions of iOS that Swift does not support, Objective-C is a good choice.

Launched in 2017, Flutter is an open-source development kit that can be used to create cross-platform apps for iOS, Android, Windows, Mac, Linux and Google Fuchsia.

It is one of the most popular cross-platform app development languages, which is best to use if you wish to create Android, desktop and web app versions of your iOS app.  



C# is a general-purpose programming language used to write applications for Windows systems. Since the .NET framework came to Linux and Mac systems, it is possible to develop native software in this language for any platform, including iOS. 

C# is a good choice if you plan to create mobile apps for both iOS and Android users. 



HTML5 is the latest HTML version that is typically used in combination with CSS and JavaScript. With the help of tools such as Apache Cordova and Visual Studio for Mac, HTML5 can also be used in developing iOS applications.    

HTML5 is the right programming language to consider if you do not wish to invest much time and resources and want to develop an iOS app quickly that can also be accessed offline. 


Factors to Consider before Starting to Develop iOS Applications 

Developing a good revenue-generating app is not an easy task and should be planned well. Here are a few pointers to be kept in mind on how to develop iPhone apps and iOS apps. 

Define the purpose

As the first step, it is important to define the purpose of developing the iOS app. You should be able to answer the questions such as: 

  • Why do you want to develop a particular app?
  • What is the problem you are trying to resolve through the app?
  • Are there similar apps in the market? How is your app different?

Identify target audience & conduct market research

Define your target audience by conducting a thorough market research. Conduct surveys and try to create a consumer persona to identify the type of users you want to target. 

Prepare a plan

Once you have defined the purpose and identified your target audience, the next step includes planning. Be as detailed as possible and try to answer questions such as:

  • What are your goals and objectives?
  • What activities and features will run on the app?
  • What is the price you are willing to pay for getting an iOS app developed?
  • Which is the best iOS or iPhone app development language and technology?
  • What security issues should be taken into account?
  • How will you measure the success of the app?
  • Do you wish to develop the versions of the iOS app on other operating systems?    

Decide whether to build the app in-house or outsource the development 

Many companies wonder whether to build the application in-house or outsource the development process. However, to remain competitive in the global marketplace, it is recommended to outsource the development services as it ensures the best possible product with reduced costs.

The mobile application market is extremely competitive, therefore, in order to stay ahead of the curve, it is important to conduct thorough market research to check which similar apps are already out there and what is your USP.  

Compliance with Apple guidelines

Apple has strict guidelines, which you or your hired mobile app development agency must abide by to ensure all the requirements related to design, user privacy and security are met. Apple only publishes those apps that meet all their requirements.


The designing process includes the following steps:

  • Wireframing: Once the concept behind the application is clear, the next step includes documenting the requirements for the design team. The team then develops wireframes – digital sketches on how the app would look like.
  • UI/UX design: The main objective at this stage is to ensure a design that is not only visually appealing but easy to use
  • Software architecture: It includes three important components of the model view controller (MVC) paradigm – data, user and software. This step ensures the scalability and stability of the app.
