When building an iOS app, the Xcode Archive & Export for iOS Step returns the following error message:
No “iOS Development” signing certificate matching team ID “*****” with a private key was found
This error indicates that the Step couldn't find an iOS Development certificate that corresponds to a valid Apple team ID for the app.
Make sure you have uploaded at least one valid "Development" type signing certificate. A "Development" type signing certificate is required even if you build an app for distribution!
