I’ve managed to stuff up my xCode installs.
I installed xCode Beta 3 and everything was normal, could build with both iOS 6 and 7.
Then I was going to update to Beta 5 but Corona is still looking for Beta 3 it seems, even though I uninstalled it (perhaps not correctly).
Since then I uninstalled version 4.6 and 5 beta, reinstalled 4.6 and still not working. Does not matter if I’m building for 6 or 7.
It is looking for something in Applications/Xcode5-DP3.app/ which does not exist anymore.

I have also uninstalled and installed Corona few times (currently using build 1187). Deleting the Corona files in Library/Application Support.
