Swift is designed for iOS and OS X software, and appears to replace Objective C as the main programming language for Apple. Let’s take a look at the pros and cons of using Swift programming language that you must know about:


  1. Swift is an open-source and general-purpose language.
  2. It is easier to learn and maintain compared to other languages since it has clear syntax.
  3. Swift reduces the code size which means faster execution.
  4. Offers better safety features.


  1. Swift is a new language that means it will take time to discover its issues, and has a limited set of library.
  2. Because of newness, it has a limited number of developers and fewer resources to learn.
  3. Lack of compatibility with past languages.


7. C#

C#(C Sharp) is an Object-oriented programming language developed by Microsoft, particularly used for building Windows applications. C# is a .net language. If you decide to learn C# then here are the pros and cons to look for:


  1. C# is ideal for building a Windows service or a desktop app.
  2. C# is one of the common programming languages hence it is easy to find C# developers.
  3. Offers better security for source code as it is available in binary form public-view. Therefore if your server gets hacked, hackers do not gain direct access to your code.


  1. C# is a compiled code and it is much more difficult to work with as you have to compile your code each time you make a minor change.
  2.  The server environment has to be Windows only to run a .net application.
  3. Compatibility with older versions of Windows is only available for the older version of .net.


8. R

R programming language is used for statistical computing and is widely popular among data miners for data analysis, polls, and data mining surveys.

“The server environment has to be Windows only to run a .net application” is not true since 2016. With “.net core” you can run your code (C#, F#, VB and many other languages) on Windows, MacOS and Linux – using frameworks like Xamarin, you can even run it on Android and iOS.
