Multiple Certificates/Provisioning Profiles in one Xcode organizer?

Question

There are several similar questions here, but none could answer my basic question:

Is it possible to have two separate developer certificates in the keychain and two

Answer 1

Yes I've produced app store builds of projects for clients several times using their distribution certificate. No need to use their developer certificate. There are many things can could go wrong here, if you have access to the client's account you can go on to the provisioning portal and check things out:

• make sure the bundle ID in the project settings exactly matches the app ID on the iOS provisioning portal (com.company.appname usually)

• make sure the app store distribution provisioning profile is marked as "valid" and shows up under the distribution certificate.

• make sure the app store build config in xcode references the client's distribution cert.

• open your keychain and make sure that the client distribution cert also has its accompanying private key. This may be the problem, it's the part usually left out. The client must export his private key for his dist cert and send it to you in the .p12 file along with the password to the .p12 file. The dist cert can't be used to sign the app without the private key!

• sometimes just quitting Xcode and restarting it helps.
