Xamarin has watchOS support:
- Add a new watchOS > App > WatchKit App project to an iOS 10 solution.
- Right-click the watchOS app project and select Set as startup project
- The simulator list should change to display a 38mm or 42mm watch option. If it doesn't change, restart Visual Studio for Mac and try again.
- With a watch simulator selected, start debugging.
Refer to the Xamarin watchOS docs for more information. Also see the release notes and API diff.
watchOS has the following minimum requirements:
- Xcode 8.0 (download from Apple)
- Xamarin Studio 6.1 (available in Stable channel)
- Xamarin.iOS 10 (available in Stable channel)
