WatchKit apps must have a deployment target equal to iOS 8.2 (was 8.3)?

Question

I just downloaded Xcode 6.3 beta 4, and my WatchKit app now fails to build with an error:

Embedded Binary Validation Utility Error
error: WatchKit apps must          


        

Answer 1

Go to Target -> Select Watch Kit App, Under deployment change value from 8.3 to

//:configuration = Debug IPHONEOS_DEPLOYMENT_TARGET = 8.2

//:configuration = Release IPHONEOS_DEPLOYMENT_TARGET = 8.2

Clean and build. Problem Solved!
