I recently updated to the release version of Xcode 13 on my Mac. Now when I upload a build to Apple using the upload endpoint (via fastlane) I get an error saying "Invalid Toolchain. Your app was built with an unsupported SDK or version of Xcode. If you plan to submit this build to the App Store, make sure you are using the versions listed in https://help.apple.com/xcode/mac/current/#/devf16aefe3b or later."
% xcodebuild -version
Xcode 13.0
Build version 13A233
I also deleted the old beta Xcode and restarted my mac to be sure. Anyone else having this issue? Any recommendations?
Thanks!
