Xamarin.iOS 9.4

Xamarin 9.4.x Releases

Xamarin.iOS 9.4

Xamarin.iOS 9.4 introduces support for iOS 9.2 and Xcode 7.2. This is not a large update from Apple so it's very close to our 9.2.x series.

Important Notes

Due to non-backwards compatible changes in Xcode 7 toolchain this version of Xamarin.iOS is only supported when used with Xcode 7 or later. This indirectly means the oldest version of iOS that applications can be directly deployed (on devices) is iOS 6.

New Features

Support for iOS 9.2 and Xcode 7.2.
