Swift Package Manager and Bitcode

[bukira]

What did you do?

Add SwiftyJSON as a SPM package

What did you expect to happen?

I could build swiftyJSON for watchOS with Bitcode

What actually happened instead?

Fails
ld: bitcode bundle could not be generated because '/xxs/Library/Developer/Xcode/DerivedData/SwiftUI-armthkmaplrjrnfxyfrdhayusjxo/Build/Products/Release-watchos/SwiftyJSON.o' was built without full bitcode. All object files and libraries for bitcode must be generated from Xcode Archive or Install build file '/xxx/Library/Developer/Xcode/DerivedData/SwiftUI-armthkmaplrjrnfxyfrdhayusjxo/Build/Products/Release-watchos/SwiftyJSON.o' for architecture armv7k
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Environment

Project that demonstrates the issue

How do I get bitcode to work with SPM, in a normal framework the project file says that bitcode is enable, but as SPM has no project I would then expect the parent project to dictate this but I cannot get this to work
