As soon as I updated xcode to 9.2 , I cannot validate my archived builds. I get this error message every time:
Invalid Toolchain. New apps and app updates must be built with the public (GM) versions of Xcode 6 or later, macOS, and iOS SDK or later. Don't submit apps built with beta software including beta macOS builds.
Is this something wrong with Apple's new relase of xcode? Otherwise, I didn't change anything that would make this project using "Beta software".
