recently has been plagued by this problem, sleepless. because before the collation of the keychain, accidentally deleted a lot of things, resulting in the re-import of the certificate for the real-time debugging when the above error occurs. From the beginning is constantly checking the data, thinking, and finally came to the conclusion that the lack of a debug certificate of the private key.
After adding a private key paired with the certificate, the successful debugging succeeds!
