Providing feedback and reporting bugs

Your feedback goes a long way towards making Xcode even better. With Feedback Assistant, you can report issues or request enhancements to APIs and tools. Include detailed information about issues, including the system and developer tools version information, and any relevant crash logs or console messages. To ask questions and find answers by Apple engineers and other developers, visit the Apple Developer Forums.

Invalid private key and certificate pairing

If you received an error message saying, 'Xcode could not find a valid private-key/certificate pair for this profile in your keychain.' This error message indicates that the Keychain Access application on your Mac is missing either the public or private key for the certificate you are using to sign your app.

This often happens when you are trying to sign and build your app from a different Mac than the one you originally used to request your code signing certificate. It can also happen if your certificate has expired or has been revoked. Ensure that your app’s provisioning profile contains a valid code signing certificate, and that the Keychain Access application on your Mac contains that certificate, the private key originally used to generate that certificate, and the WWDR Intermediate Certificate.

For instructions on how to resolve this and other code signing errors, review the Code Signing Support page.
