The Right Framework for Your iOS App Development- Flutter vs Swift

Flutter is an open-source UI software kit formed by Google which permits cross-platform app development with a single codebase. But Swift is a high-level, all-purpose, multi-paradigm, compiled language introduced as a substitute for Apple’s conventional programming language which is Objective-C.


  • Integration & Development – For Integration & Development also, both Swift & Flutter are considerable. Flutter has many plugins & packages you can integrate into apps. Plus, it permits the integration of third-party services such as Google Maps and Firebase. Swift also has several system frameworks and APIs that help develop effective iOS apps. Additionally, Swift along with XCode IDE provides many higher tools and qualities for iOS app development.
  • Development Time or Speed to Market – ‘Swift’ the name itself means swiftness – swiftness in terms of development speed & agility. Being more accessible and having a smaller learning curve, it greatly increases the speed of iOS app development. The XCode command line permits to evaluate the Swift Native iOS application development time, that is displayed after the expansion process is finished, and the build command is implemented from product menu. Swift also provides a varied range of system APIs & frameworks that accelerates the development speed or time to the market.
  • Application Size – Flutter has a compacted runtime that aids building small & fast mobile apps with limited expenditures. It has a varied range of tools & optimizations like tree sharing as well as code spitting which aids to further decrease the application size. Swift being native iOS framework assists build small & efficient iOS apps. Its compiler supports to optimize functioning and decrease size of the app. It also provides a wide range of optimization options like whole-module & link-time optimization. These add to further lessen the size of Swift apps.
  • Performance – If budget is not your restriction and you want to have separate apps developed for every platform then Swift is your answer, being a native framework, it gives greater efficiency & helps deliver quick, smooth, and reliable apps. Swift produces extremely optimized code & offers a set of system APIs, that can boost app performance. However, if you demand for a framework along with cross-platform functionality which offers better cost productivity, then Flutter is similarly efficient to make iOS apps. Flutter uses layered building that reduces the overhead of platform-specific APIs, resultant in better functioning.

In conclusion, both Flutter & Swift are outstanding choices for mobile application development, as well as the decision on which one to use depends on your particular needs & preferences. Eventually, the choice among the two depend on your primacies and the requirements of your application.
