I keep getting this error when trying to submit an update using the Xcode 9 GM:
iTunes Store Operation Failed
ERROR ITMS-90534: "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."
Apple's developer site states that iOS 11 submissions are now open. Has anyone been able to successfully submit an app using the GM?
