It also allows to monitor trends in the media world and track statistics about daily changes in news tonality. This web application was built with Python on top of the Django web framework and is unique on the Ukrainian market.

The Top Programming Languages for Mobile Application Development

Our Choice for iOS Mobile App Development: Swift

Swift is a multi-paradigm, general-purpose, compiled programming language developed mainly as an alternative to Objective-C in the development of native iOS and Mac OS apps. It is a relatively young language released in 2014 by Apple Inc. However, Swift already can be considered the primary programming language for iOS application development that is going to displace its predecessor, Objective-C, in the near future.

Key Swift features:

  • Swift was built to be fast. Using LLVM as its compiler framework, Swift code is transformed into optimized native code that gets the most out of modern hardware.
  • Swift has a concise, simple, and clean syntax that is similar to the English language. That’s why it is easier to write and maintain.
  • Swift is a programming language with a serious safeguard that increases readability and reduces errors in code.

Talking about the popularity of Swift, it’s worth mentioning that Swift got listed on the 6th position in a category of the most loved programming languages according to the 2019 Stack Overflow’s annual survey.
