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It can also happen if your certificate has expired or has been revoked.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. Apple Security Updates For information on the security content of Xcode updates, visit the.

You will need to update Xcode to the newest version (Xcode 8 or newer).
Go to the App Store application and check “Updates.” After updating Xcode, be sure to launch the Xcode application and accept the Apple license terms.

Alternatives The is an open source project to provide the GCC compiler and related tools. In a recent blog post, the project maintainer recommends installing the Xcode Command Line Tools because the open source project is unable to duplicate the complete Apple package (notably, the Node software project isn’t supported). Start Coding! With the GCC compiler installed, you can install any Unix system tools you need for software development. To install Rails, see the article. Want to learn Ruby on Rails?
