I previous developed apps in xcode 9 beta versions but downloaded the GM seed yesterday. I have "cleaned" the projects, re-built and uploaded them for processing.
I am still receiving the following automated message from apple.
Invalid Toolchain - New apps and app updates must be built with the public (GM) versions of Xcode 6 or later, macOS, and iOS SDK. Don't submit apps built with beta software including beta macOS builds.
Will I need to re-build and upload when the final xcode version is released.
