IOS 10.8.5
Xcode 5
Unity 4.2.1

I build run the project, it reports:
UnityException: Launching IOS project via Xcode4 failed. Check editor log for detailed.

How to fix it?

Don’t do a build and run, as per the posts on this forum. Do a build, then open the project in XCode.

Are there any plans to fix this?
