Upgraded to Xcode 5.1. Now my game will not build properly. Ton of errors.

My guess is that someone at Unity needs to update the iOS export to account for the recent iOS 7.1 update. Apple wants the games to run on iOS 7.1. In Unity I can set the target iOS version to "unknown" which when opened in Xcode 5.1 will show the "Deployment Target as 4.0." With this I am able to build to my iPad Air running 7.1. HOWEVER, when the Deployment Target is changed to 7.1 all the errors come flying out.

See the errors for yourself:

Update: To be clear, I can build the game to the iPAD with deployment target 7.1 selected, but one of the yellow flag errors is called "Validate Project Settings : Update to recommended settings (which are listed as Target - Automatically select architectures, Project - Automatically select architectures, and Project - Enable Build Active Architecture Only When Debugging). After clicking "Perform Changes" and trying to build again, that's when I get the errors listed above.

Thanks.

 

You should never let Xcode to fix Unity project settings. It makes too many incorrect assumptions.

 

Yes, you are correct.

I needed to properly set my architecture and valid architecture fields under Build Settings. This website helped: Xcode5 Arm64

I set Architectures to: armv7 (adding armv7s to the list resulted in failure).
I set Valid Architectures to: armv6 armv7 armv7s arm64.


The few errors I got afterwards came from having the Game Center disabled. Once I turned it back on, eventhough I don't use it, the errors cleared.

The only flags remaining are the Deprecations for 'wantsFullScreenLayout', and 'presentFromViewController.'



Thanks.
