Use Cases:

  • Cross-platform mobile applications.

  • Applications that require rapid development and iteration.


  • Large developer community and extensive libraries.

  • Code reuse between web and mobile applications.

  • Speedy development process.

5. Python

Overview: Python, known for its simplicity and readability, can be used for iOS development through frameworks like Kivy and BeeWare.


  • Easy to Learn: Python's syntax is clear and straightforward, making it a great choice for beginners.

  • Versatile: Extensive libraries and frameworks for a variety of applications, including web, mobile, and data science.

Use Cases:

  • Prototyping and developing simple iOS applications.

  • Applications that require integration with machine learning models or backend services.


  • High productivity due to rapid prototyping capabilities.

  • Extensive support libraries and frameworks.

  • Strong community support.

6. Kotlin

Overview: Kotlin, officially supported by Google for Android development, can also be used for iOS development via the Kotlin Multiplatform Mobile (KMM) project. It allows sharing code between iOS and Android.


  • Interoperability: Kotlin is fully interoperable with Java, and Kotlin/Native allows compiling Kotlin to native binaries.

  • Concise Syntax: Less boilerplate code compared to Java.

Use Cases:

  • Cross-platform applications with shared business logic between iOS and Android.

  • Applications that benefit from Kotlin’s modern features.


  • Shared codebase reduces development time and effort.

  • Strong support from JetBrains and Google.

  • Robust and type-safe language features.

7. Dart

Overview: Dart, developed by Google, is primarily used with the Flutter framework for building natively compiled applications for mobile, web, and desktop from a single codebase.


  • Fast Development: Hot reload speeds up the development process by allowing changes to be seen immediately.

  • Expressive UI: Flutter’s widget-based framework allows for highly customizable and expressive UIs.

Use Cases:

  • Cross-platform mobile applications with a single codebase.

  • Applications that require a high degree of custom UI design.


  • Single codebase for multiple platforms.

  • Strong performance due to native compilation.

  • Growing community and support from Google.

8. Ruby

Overview: Ruby, known for its simplicity and productivity, can be used for iOS development through the RubyMotion framework, which allows writing native apps in Ruby.


  • Concise and Readable: Ruby’s syntax is clean and easy to understand, promoting quick development.

  • Powerful Libraries: Access to a variety of libraries for different functionalities.

Use Cases:

  • Rapid prototyping and development of iOS applications.

  • Applications that benefit from Ruby’s dynamic nature.


  • High productivity due to Ruby’s expressiveness.

  • Strong focus on simplicity and ease of use.

  • Access to the Ruby ecosystem and libraries.

9. Lua

Overview: Lua is a lightweight, high-level scripting language often used in game development. It can be integrated into iOS applications using frameworks like Corona SDK.
