I had Xcode 6.3 beta and iOS 8.3 beta, I updated to the public final versions and now I cannot run anything, getting this error:
No provisioned iOS devices are available with a compatible iOS version. Connect an iOS device with a recent enough version of iOS to run your application or choose an iOS simulator as the destination.
I have tried everything other posts have said with no luck (my iPhone is "used for development", Base SDK = latest iOS (iOS 8.3), Xcode 6.3 (6D570), iOS 8.3 (12F70), Deployment target=8.0, deleted derived data, restarted Xcode, opened up iTunes)
Anyone out there having the same problem?
