Xamarin
Xamarin uses C# programming language to be used as a tool for application development technology. Programming languages like Xamarin.Mac, Xamarin.iOS, and Xamarin.Android aids the developers with about 90% of code reuse throughout iOS, Windows and Andriod.
Reasons You Should Use Xamarin For Your Android And IOS Cross-Platform Development.
Exceptional Work
The Android and iOS have features (UI and SDK) which are predominantly different to both of their platform’s appearance and behaviour. Such features are central to iOS and Android.Xamarin includes both iOS specific .NET classes and Android specific .NET classes which allows the language to take advantages of each platform’s unique features.
Faster Time-To-Market
Allowing the code application logic,Xamarin allows sharing it across iOS and Android.Xamarin allows you to focus the efforts on app building features and later shipping the app. This reduces the time of development to almost half.
Ready for Windows
Using Xamarin in order to create the iOS/Andriod apps makes these apps all ready to support support Windows phones. The shared logics created for iOS and Android apps can be supportive for the windows phone.
