Certificate Has Either Expired or Has Been Revoked

The certificate used to sign AppName has either expired or has been revoked. An updated certificate is required to sign and install the application

Managed to solve the issue by moving the apps source files to a new directory. Still no idea what exactly was causing the issue, but this fix works well enough.

Xcode 9.2 certificate used to sign is either expired or revoke

OK I figured it out. The error message was not helping at all.

This was a project actually exported from Unity3D. In Unity3D I have some post build scripts that modifies Xcode project. It was adding a framework as embedded framework in post build script. I just removed the framework from embedded frameworks and add it again (in the general tab) and it fixed the problem.

How can I fix a revoked certificate?

It sounds like your Apple ID password may have changed since you last used Xcode - that would explain your Code Signing Error: The user name or passphrase you entered is not correct error. Try navigating to Xcode > Preferences... and view the Accounts tab, and check for any errors there. Xcode may prompt you to sign in again with your Apple ID.

Your iOS Development certificate has been revoked

If you delete/ generate new certificate in Provisioning Portal(Certificates) then you get these types of messages "Your Development Certificate Has Been Revoked - you have revoked your Development certificate and it' s no longer valid".

To overcome this you need to generate provisioning profiles with the newly created distribution certificate, sign the build using the same, recreate the build and resubmit the app for review to AppStore.
