I was having the same issue.
What I did was open up the app in the corona terminal so that I could read the build output, and at the bottom there was a comment along the lines of “Ambiguous distribution profile blah blah found in /Users/nick/Library/Keychains/login.keychain”
I went to the command line and did open /Users/nick/Library/Keychains/login.keychain, and in there, sure enough, there were 2 certificates for my distribution profile. The one at the top had a red x in it. Deleting that certificate fixed my issue. Now the output in the build terminal looks like this:
/Users/nick/Desktop/PandaDrop.app: replacing invalid existing signature
/Users/nick/Desktop/PandaDrop.app: signed bundle with Mach-O thin (armv7) [PandaDrop]
In a nutshell, if you don’t see the ‘signed bundle’ line in the terminal then it’s safe to say it wasn’t signed.
Hope that helps. [import]uid: 70 topic_id: 4105 reply_id: 13765[/import]
