I am trying to sign an app with my client's certificates. I have received the following file from the client

I tried installing the ios_distribution certificate and the key (.p12). Also I have installed the provisioning profile. Now when I try to sign the app with the provisioning profile, it does show up in the drop down but I get the following error:-

No "iOS Distribution" signing certificate matching team ID "7S977Lxxx" with a private key was found

How can I solve this issue? Any help is appreciated.

You need to have the private key of the signing certificate in the keychain along with the public key. Have you created the certificate using the same Mac (keychain) ?

Solution #1:

• Revoke the signing certificate (reset) from apple developer portal
• Create the signing certificate again on the same mac (keychain). Then you will have the private key for the signing certificate!

Solution #2:

• Export the signing identities from the origin xCode
• Import the signing on your xCode
