After analyzing all these, you can move to the next phase, which is programming languages. Not all the languages are the same for developing iOS apps, where you can start by knowing the languages that are used to write iOS apps. We, “REXO IT,” can assist you by providing the best guidelines to get started.

Types of Programming Languages

Different types of programming languages are available for building iOS apps. The languages for programming help with coding conveniently. However, several programming languages are available for developing and writing code for your iOS apps. Here, we are going to describe some of the best programming languages for iOS app development.

The programming languages for iOS Apps Development are;

  • Swift

  • Objective-C

  • Flutter

  • C#

  • HTML5

These are the popular programming languages for developing iOS applications. All of them have different syntaxes as the development process while writing codes.


The programming languages enhance the iOS app development process conveniently. Swit is one of the most preferred languages to shape the future of iOS app development. It was released in 2014 announced by Apple at the Apple WWDC event. According to the professionals, Swift was ranked as the 11th most popular language on the internet today. The programming language appears with general-purpose programming, where the developers used it to develop superior-quality native apps specifically for iOS. This language appears with a convenient design to work comfortably with frameworks like Cocoa Touch and Cocoa. It also has the best scalability interoperability, especially with the Objective-C programming language. Also, it is an open-source language for programming, which provides the fastest iOS app development. Swift is also preferable to get the best data security in development, and that also includes the automatic memory arc. But this coding language for iOS apps development is acceptable for a limited user base.

Swift programming language is preferable to use in the scale and quick app development process.  Additionally, you can use this for iPhone app programming language, iPad, Apple Watch, Apple TV, and Mac.


Objective-C is another excellent programming language for developing iOS applications. It is a predecessor of Swift, and that is also acceptable for coding iOS apps. However, the objective-c language was built as an extension of the object-oriented programming language C, which contains similar properties. This language was developed in 1984 by Brad Cox and Tom Love. This language is now a general-purpose programming language, which is still compatible with Mac OS and iOS. Also, it was the primary iOS coding language to develop apps before Swift came around. There are several characteristics included in this programming language. It comes with an expressive message syntax with dynamic run-time. You can also get access to Apple technologies with this programming language, including its automatic garbage collection feature. The Objective-C and Swift programming languages are comparable in terms of readability and coding, which also includes execution time, code maintenance, and many more. Additionally, this coding language was developed in the early 1980s, and that makes it a bit outdated as an iOS app development language in 2022. 

Additionally, it also has several security issues with limited functionality and a lack of updates, which weighs down its popularity. This programming language has seniority, and it is frequently seen as a stable and mature language to develop iOS apps. It is preferable to use this objective-c language while developing or updating apps for the older iOS versions that Swift does not support.


Flutter is an excellent programming language for developing iOS apps. It is a popular coding language for iOS apps because of its convenient working features. However, the flutter was developed by Google in 2015, but it was officially released in 2017. This language for programming is a highly versatile open-source development kit. You can use this coding language to build apps for iOS, Android, Mac, Linux, Windows, and Google Fuchsia. The best part of this programming language allows software engineers to build aesthetically attractive and intuitive cross-platform apps comfortably. That is the reason Flutter is considered by both android and iOS developers. Additionally, this programming language is highly cost and time-efficient, which comes with full customization capability. Regarding the widgets of this Flutter coding language is available as an open-source language and also offers a limited and young talent pool. The Flutter coding language is the best option to use the most popular cross-platform app development language to create iOS apps. You can also use this programming language to make the Android, desktop, and Web app versions. Flutter language is acceptable to use, and it can save a lot of time. Also, by using this iOS app programming language, you can build app versions for all compatible OS’ and platforms with a single codebase.


C# is a high-level programming language to use for building iOS apps. It is also an open-source coding language, which makes iOS App Development much easier for intermediate to advanced level developers. This language also comes with a vast talent pool, which supports cross-platform app development by offering a rich library.
