Xcode 4 -reinstalls keychain certs that I delete

Question

I am getting this error:

CodeSign error: Certificate identity 'iPhone Developer: XXX' appears more than once in the keychain. The codesign tool requires there only be one.

At first I though, no worries, I will just go into keychain and delete the duplicate (older) one, which I did. I went back, closed Xcode, reopened Xcode and project, same error. wtf I though to myself. Back into keychain and the cert is there again. I delete both certs, repeat, and notice as the project loads, the two certs I deleted pop back into the keychain.

After much searching, I ensured I did not have the cert in the system keychain, which I did not. Also did a clean and rebuild. When I had duplicates with Xcode 3 I could just clean up the keychain duplicate and I was good. But with Xcode 4 it literally just reinstalls them somehow when I open the project. I even deleted all .cer files on my system that it might possibly be pulling them from.

Any suggestions?

Answer 1

The solution was to go into organizer - under library - provisioning profiles, delete all of them and then reinstall any profiles I still needed.

Answer 2

I had this same problem and the solutions above did not solve my problem (well nearly).

I had the same duplicate developer ID/certificate that everyone is complaining about, and I tried deleting all my profiles, revoking/reissuing my cert, making sure there were none in the system keychain, restarting, etc etc.

In the end it turned out there was a certificate in the system keychain, one that had expired and so was hidden by default in the list.

Make sure you can see expired certificates in KeyChain

To do this:

1. Open Keychain Access
2. Click View menu
3. Click Show Expired Certificates
4. then look for, and delete expired developer certs
