I've struggling with this for hours. I have 2 same provisioning profiles I've created and the new profile didn't substitute the old one (which expires 6 days earlier than the new one). Through the XCode 5 menu I can't seem to delete the duplicate provisioning profile. Any workaround in this situation?
If you delete the profile from the Apple development a/c and hit refresh in XCode (Using xcode>Preferences>Accounts) then these profiles will be gone.
You can remove them from the this directory on your machine:
"~/Library/MobileDevice/Provisioning\ Profiles"
