Such problems are due to current Provisioning Profile does not contain APNS information, as the Provisioning Profile is created BEFORE creating the APNS certificate.
Therefore, to solve the problem, create a new Provisioning Profile & select the Provisioning Profile in Xcode will clear the error.
Also, when you add push, I believe you have updated the certificates in keychain too.
