Fixing the Expired Certificate for iPhone Development Environment


This is a short guide to resolving the issue of the expired certificate using XCode with the iPhone SDK – its probably relevant for setting up your certificate from scratch as well. I am not totally convinced this is the best way of fixing the expired certificates for iPhone Development, but it worked for me so.

The Environment:

The development environment  is a follows:

  2. SnowLeopard OS;
  3. XCode 3.2 ; and
  4. iPhone developer program member.

The Problem:

You’ll may get a variety of messages when the certificate expires and they will include:

a valid signing identity matching this profile could not be found in your keychain

or :


code sign error: the identiy matching this profile could not be found in your keychain



You currently do not have a valid certificate

Getting a new certificate:

  1. From Applications->Utilities Click KeyChain Access
  2. From the Keychain Menu Select Certificate Assistant->Request a Certificate From a Certificate Authority
  3. Enter your email address and your common name and select Save to disk
  4. Go to and login
  5. Go to the Provisioning portal in the iphone developer and select Certificates
  6. Remove the existing certificate
  7. Add a new certificate
  8. Choose File selects the file you created in step 3
  9. Click Approve
  10. Reload the page. Now you should see the download button.
  11. Click Download
  12. Then select it the downloaded file
  13. You will receive a dilog stating “Do you want to add the certificates from the file…. To a keychain”. Select YES.
  14. Click Add and you should see the certificate list with the new valid certificate displayed.
  15. That’s all you should have to do however you may notice a dialog asking you to use the new key – just select Allow or Always Allow.
