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

Question

I just updated my project from 8.2. to 8.3 (using the latest xCode Version 6.3 6D570). Now i get this error

error: WatchKit apps must have a deployment target equal to iOS 8.2 (was 8.3).

The project and all targets are set to Latest SDK 8.3

What did I miss?

Answer 1

I resolved this by:

1. Right-clicking my PROJECTNAME.xcodeproj file and choosing "Show Package Contents".
2. Opening project.pbxproj in a text editor.
3. Changing all instances of "IPHONEOS_DEPLOYMENT_TARGET = 8.3;" to "IPHONEOS_DEPLOYMENT_TARGET = 8.2;"

After this change my project compiled and ran fine.

Answer 2

Build successful. I just changed the iOS Deployment Target of the Watch App Target to 8.2.

Why is that?
