Xamarin, founded in 2011, is a cross-platform development solution that can help simplify development processes by enabling developers use C# to build Android, iOS, and Universal Windows applications with native UIs and share code across several platforms like Windows and Mac OS.

Since, Xamarin permits writing codes in C#, there is no need for developers Swift, Objective-C or Java to build apps once you understand C#. Xamarin is very good for beginners in app development.
