when I run my app on iPad it builds my app and then I got error:
"Could not launch 'AppName', timed out waiting for app to launch".
Though, after this error, app is working perfectly on device. I think that it’s caused by some sort of setting “Debug is not allowed” or something like that.
I was having the same problem – Deleting derived data didn’t work. In my case I found out that I was building the debug with an Ad Hoc provisioning profile.
