What's New in this Release

Release History

This version of Xamarin.iOS corresponds to our xcode11.3 (d16-4 based) milestone.

  • January 13, 2020 - Xamarin.iOS 13.10.0.17

You can learn more about how we ship our releases in the Visual Studio 2019 Release Rhythm document.

January 13, 2020 - Xamarin.iOS 13.10.0.17

This version is included in Visual Studio for Mac 8.4.1 This release includes new API to support Xcode 11.3.

Important

Xcode 11.3 doesn't ship an iOS/tvOS 13.3 SDK, therefore the maximum deployment target remains 13.2

Updated frameworks

Issues

  • 7441 - [Generator] Fix InvalidCastException for managed instances of conflicting type.
  • 7564 - [Runtime] Fix ARM64 trampoline crash.

Enhancements

  • 7483 - [Linker] Additional mtouch arguments now support --optimize=experimental-xforms-product-type so the linker does not mark NSObject subclasses from Xamarin.Forms.Platform.iOS.dll assembly.

Known Issues

Note

Using a 13.3 deployment target results in an mtouch error MT0074. This is because the 13.3 SDK is not yet available in Xcode, 13.3 will be removed from the deployment target options in a future release.

Using an older Xcode version

Using an older Xcode version (than the one mentioned in the above requirements) is often possible. For more information see the following documentation.
