Following the Xcode instructions, I disabled bitcode in the main target (there was no visible build option for bitcode in the watch app or watch extension targets) but the build failed with this error:
target 'xxxx Extension' has bitcode disabled (ENABLE_BITCODE = NO), but it is required for the 'watchos' platform
Xcode 7.2.1, I selected WatchOS (not WatchOS 1) when I added the watch targets.
Any ideas?
Of course with bitcode on, the MMWormhole stops the build.
