since I updated my Xcode to 5.0.1 with iOS 7.0.3 I'm unable to run the UI tests. Zucchini is launching Instruments, but can't exec the UI tests in the app and failed with the message, that the app is not fronMost.

Just now I found out that if I sym link the iPhoneSimulator 7.0.3 folder to 7.0 than zucchini works again.
