64 bits watchOS support
Xcode 10 GM added support for 64 bits watch application, aka
arm64_32. The current app store submission process requires this architecture to be included in your application when including watch support. You can workaround this with [https://github.com/xamarin/xamarin-macios/issues/4810#issuecomment-421338365](these instructions).
Trying to run a watch app on the new Series 4 Apple Watch will fail with this error:
IncorrectArchitecture: Failed to find matching arch for 32-bit Mach-O input file ... error MT1006: Could not install the application 'MyTestApp.app' on the device 'MyDevice': AMDeviceSecureInstallApplicationBundle returned: 0xe8000087 (kAMDIncorrectArchitectureError).
This is because the S4 device can only execute native
armv7klike previous watches.
Please read https://github.com/xamarin/xamarin-macios/issues/4864 for more information and a workaround.
Apple Breaking Changes
- rdar://41123682 Apple changed
TVElementUpdateType*enum values. Please test your application if you're usinf this type.
- rdar://43425168 Apple changed
IN*WorkoutIntentResponseCodeenum values. Please test your application if you're usinf this type.
Apple Non-Breaking Issues
RPBroadcastPickerViewsymbol is not present in simulator. If needed you'll need to test this on devices.
- Disabling the managed linker for device builds can generate object files that are too big for the 32bits native linker
ldto process properly. The workaround is to enable the managed linker (e.g. Link SDK) on your projects.
Using an older Xcode version
Using an older Xcode version (than the one mentioned in the above requirements) is often possible, but some features may not be available. Also, some limitations might require workarounds, e.g.:
- The static registrar requires Xcode headers files to build applications, leading to
MT4109errors if API are missing. In most cases enabling the managed linker will help (by removing the API).
