问题
I've been stuck on this for a few days. Really appreciate it if anyone can point me the directions.
All of a sudden I can't build the Watch App onto the simulator - I can still build to the device tho. It shows an error as below. It looks like target architecture issue but the build settings Architectures is set to $(ARCHS_STANDARD).
After the error message was shown, the simulator had the App with unfinished install. Tapping on it triggers another dialog: This app needs to be updated by the developer to work on this version of watchOS.
