My bundle id is correct however it is not working. Error message is ; "Code Sign error: The identity 'iPhone Developer' doesn't match any valid, non-expired certificate/private key pair in the default keychain"

Answer 1

Go to Organizer, choose Device tab, and under Provisioning Profiles (first entry in the left panel) you should see your certificates. Are they valid? If not you may be missing private key.

If you go to your Keychain, under Certificates you should see your developer profile. They should be expandable and when you expand you should see there's the private key. Without it the certificate won't be valid.
