The great thing about iOS is that almost any device such as iPhone, iPad, or iPod touch can run the same apps, so your customers can enjoy your app no matter how big their device is or which OS they’re using.

Xcode, Objective-C (or Swift), Cocoa, and Interface Builder. If these words seem intimidating to you, or you just want an overview of what they mean, this is the article for you.

What is iOS Programming Language?

 iOS – a mobile platform that is a closed operating system. iOS is a mobile operating system that runs on Apple’s mobile devices and is a more secure operating system than android.

Every platform employs a distinct language, such as JavaScript or C++, to create its applications. Similar to them, iOS creates its apps using the language Swift.

If you go to your friends right now and shout “Android or iOS”, you are either going to watch them choose Android or chant back iOS. This is war itself. But we can not deny the superiority of Android. 

According to mobile security statistics, iOS has 20% fewer serious vulnerabilities than Android. This is because of the programming languages that iOS has been using. The top programming language for iOS apps are:

  • Swift
  • Objective-C
  • React Native
  • Flutter
  • Java
  • C#
  • HTML5

1) Swift 

As mentioned earlier, Swift is one of the most popular languages for influencing the direction of iOS app development. Swift is indeed a broad-sense programming language that is utilized to create high-caliber native iPhone apps.

It was released in 2014 and is one of the most well-known coding apps for iPhone programming languages.

When Should iOS App Developers Utilize Swift?

Swift will be a fantastic option if you want to relatively rapidly build an application that you can easily develop in the future. The language guarantees a quick development cycle and the ability to produce safe, dependable code. Additionally, it is frequently updated, making any changes to your application simple.

2) Objective-C

Swift wasn’t even in this game till after objective-c. Object-oriented structured programming C was extended to create this app coding language, which has many of its characteristics.

It was developed in 1984, It was the main iOS coding language prior to Swift and is currently a general-purpose programming language that still is interoperable with Mac OS and iOS. 

It is frequently regarded as an established and developed language that has:

  • Dynamic typing
  • stability
  • maturity

It was out of date because of its numerous drawbacks. The fact that it is not an open-source language makes learning it challenging. Other drawbacks include security vulnerabilities, a lack of upgrades, and restricted capability, which reduces its appeal to the general public.

When Should iOS App Developers Utilize Objective-C?

There are very few situations in which Objective-C will be preferable to Swift. It’s an advanced language that might perhaps be a little dated (the last version was released in 2016). Finding developers who can program in this language can be difficult as its use is dwindling.

3) React Native

Facebook unveiled the cross-platform React Native technology in 2015. It is currently one of the most well-liked cross-platform tools. It enables software developers to construct native applications using website technologies by employing JavaScript.

When Should You Develop a Mobile App Using Flutter?

It’s important to take Flutter into account, especially if you want to develop not only an iOS app but also a PC and web version.

Additionally, as this tool is built on the Dart programming language, it will be the best option for your business if your team members are familiar with it.

5) Java

Java is a general-purpose programming language that is both, class-based and object-oriented. Its code can run on any platform without needing to be recompiled.

  • It is flexible.
  • Suitable – for both native and cross-platform app development.
  • Has a wide talent pool.
  • Highly secure
  • Scalable and updateable

But this language has cons of its own, such as poor performance, and complex code is a type-heavy language and requires significant memory space.

While Should Java Be Used When Creating iOS Apps?

Java is not a popular option for iOS app development, despite its popularity and flexibility. However, you should think about employing the same programming language to produce the iOS version if you currently have an Android mobile application that has been developed in Java.

  • If you do not want to spend a lot of time and money developing an iOS app, HTML5 is the ideal option.

It might not be the best option, though, for highly efficient and high-quality iPhone apps. It has limited functionality and media licensing issues.

When Should iOS App Developers Adopt HTML5?

If you want to quickly create a straightforward iOS application that can also be used offline, HTML5 is the best option. If you have HTML5 experts on your team who can create this kind of application, it would be wise to take this option into account.

What Is a Typical Salary for an iOS App Developer?

Without a question, iOS developers make a good living.

According to GlassDoor, the total salary of an iOS developer is $110,406/ yr with a $97,539 annual average salary.

  • The highest-paid iOS developers can make up to $172,000 annually.
  • The average yearly compensation for a mid-level iOS developer is $114,000.
  • Junior iOS developers at the entry-level might expect to earn $40,000.

How Long Does It Take To Learn the iOS Programming Language?

It depends on your background, whether you were a programmer or you are deeply acquainted with programming languages. If you were, then learning the iOS programming language should not be that hard for you. 

Getting a firm grasp of iOS coding takes three to twelve months. However, if you choose to pursue a bachelor’s degree, it can take up to four years.

Although it is a good idea to be familiar with Objective-C before learning Swift. This is because Objective-C is an older more complex programming language than Swift, which is a modern programming language and is easy to understand. 

Is It Easy to Learn the iOS Programming Language?

pexels thisisengineering 3861972 1

No, the iOS programming language is difficult to learn. Although, Swift has a straightforward syntax that is simple to understand even if you have never written code before.

Learning iOS still demands a lot of effort and devotion, even though Swift has made it easier than it once was. You can learn them by taking a programming course or by reading a book related to these languages. 

 It is a good idea to be acquainted with other programming languages, especially Objective-C.

Is it Best to Specialize in One iOS App Language or to Diversify? 

When it comes to developing iOS apps, there are two main approaches: to specialize or diversify.

Specializing in a single language is a good way to get really good at that language. If you’re looking for a career as an iOS developer, it’s probably best to choose a language that’s popular and in high demand, like Swift, so that you can have a better chance of landing a job once you’ve completed your education. In addition, specializing in a single language makes it easier to find resources online because there are fewer people using it you’ll have fewer questions unanswered by Google.

Diversifying yourself by learning multiple languages might seem like a strange idea because it seems like extra work that doesn’t always pay off. But if you’re interested in having more than one career option open up for you, then learning multiple languages is extremely beneficial because employers often prefer developers who know more than one language. Learning another language also helps you understand how different programming techniques work together once you learn how one works, the process becomes much easier when learning other languages.

Tools Needed to Learn the iOS Programming Language

The following are the tools you absolutely must have when learning the iOS programming language.

1) Xcode 

Everything you require to create, test, and release apps for all Apple platforms is included in Xcode. With its improved editor tools, you can develop more quickly. You can also begin testing and exporting from Xcode Cloud via TestFlight as well as the App Store.

2) Swift Playgrounds 

Swift is a potent programming language developed by Apple that professionals use to create today’s most well-known apps. It is a ground-breaking software for iPad and Mac that makes learning and experimenting with Swift fun. Swift Playgrounds is ideal for students just starting out because it doesn’t require any coding skills.

Players must figure out how to enter and test code in Swift Playgrounds until they come up with the ideal solution, similar to how they would in a puzzle game. They learn to write code in Apple’s Swift programming language, which is used by qualified developers to produce iOS apps.

3) Objective-C Playgrounds

They eliminate the need for the standard edit-compile-run debug cycle by allowing you to immediately test out pieces of code and observe outcomes in real time.

4) Mac OS X 

Every Mac runs the macOS operating system. It enables you to perform tasks that other computers simply cannot perform. This is so because it was built to work with the hardware that it uses, and vice versa. A vast collection of exquisitely made programs are included with macOS.

5) iOS Simulator 

The Apple iOS Simulator is a tool for creating and prototyping your mobile app and is included with Xcode. The iOS Simulator is significantly constrained as a testing environment, even though it may be used to test the fundamental functionality of your app.

Without having to design the user interface or write any code, you can build and run your app on a virtual or actual device after creating a project.

The iPhone, iPad, or Apple Watch user interface is displayed in a window on your Mac computer via the simulator app.

Bottom Line

Swift is a lot better language and it can be used to develop quality mobile applications, it will be interesting to see how Apple developers are using Swift in upcoming projects. 

But from my perspective, I am delighted that Apple has created such a great tool for creating applications. I think that many developers will find Swift easier to use and more convenient than Objective-C, which Apple is also committed to supporting.


Is iOS Coded In C++?

The language used to create iOS apps is not really C++. You merely need to use it with a built-in C++ library; nevertheless, that does not imply that you can construct iOS apps.

Is Swift Written In C++?

The majority of the Swift compiler is written in C++, and this won’t change soon. Swift can be used to add to the standard library, but C++ is required if you wish to add a new language feature or do certain optimizations.

What Language Is Used To Develop iOS Apps?

Swift and Objective-C are the two primary programming languages for creating native iOS apps. All Apple products can be programmed in either of these two languages, but they are not interchangeable.

What Language Are iOS Apps Written In?

The iOS Operating System Runs Mostly in Two Languages: Swift and Objective-C.
While it is possible to create iOS apps in other languages, doing so may need major workarounds and extra effort.
