AppCode targeted device families not valid (iPad iOS 8.1)

According to JetBrains, it's a problem with the xcodebuild tool in Xcode 6 rather than being an issue with AppCode. Hopefully something Apple will fix soon!

I had that as well: Xcode builds fine, Appcode does not. There is no evident reason for that - the target etc looks fine. It seems to be a bug in AppCode 3.0.6 that seems to be fixed in the 3.1 EAP version. With 3.1 the project builds fine here.

Just had this problem as well in Appcode. If you set "Targeted Device Family" in Appcode's target to "1,2" (iPhone and iPad), it worked here.
