Code Sign error: Provisioning profile ‘388E4 … AA58’ can’t be found


I got the above error and after a search, found this link that saved the day:

http://stackoverflow.com/questions/1760518/codesign-error-provisioning-profile-cannot-be-found-after-deleting-expired-prof

The steps I took to resolve this were:

1. In Finder, right-click on the xcodeproj file.

2. In the options box, click on Show Package Contents.

3. Right-click on the .pbxproj file and select to open in TextEdit.

4. Do a search on that file for the long string of numbers.

5. Comment out the line and save (add /* before the line and */ after the line).

6. Restart Xcode, reopen the xcodeproj file, and do a Product > Clean. It should start up fine if there were no other problems.

If you don’t know any Javascript, the learning curve may get steeper because you may have a hard time debugging your code or adding extra features. Continue reading →
