TestFlight Fails to create IPA

Question

I'm using XCode 4.4.1 to create an IPA file for TestFlight AdHoc Distribution. If I go through the Organizer to create the IPA file, everything works great and TestFlight just works.

Here's the problem. If instead of using the Organizer to create the IPA, I allow TestFlight Co-Pilot to detect the new archive, I get a popup that TestFlight has noticed the new Archive, and I click the "Upload" button. But then, I get an error that the IPA file could not be created. The error appears to have something to do with signatures, but I'm using the same signatures as I do when creating the IPA though XCode's Organizer. Here's a screenshot of the actual error. Any ideas on what I might be doing wrong?

Answer 1

I had the same problem with the installation of Xcode 4.5.

The solution was to install " Command Line Tools ".

Xcode > Preferences > Downloads > Command Line Tools

Answer 2

After contacting TestFlight support, I was finally to get it working. Try this in a terminal:

sudo ln -s /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/codesign_allocate /usr/bin/codesign_allocate
