I keep getting "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. (ID: db8516fc-1577-4462-a983-bf8c57483cec)"
when I am attempting to upload a update that adding support for iOS 17 and iPadOS 17 of my app to App Store Connect!
I am on Xcode 15 RC which was released on September 12, 2023.
Anyone can fix this error?
