I have an app I am toying with and I am seeing the following error in github's Xcode automation from Apple. My other apps work fine fine in xcode cloud with the same project setup.
Run scheme_list=$(xcodebuild -list -json | tr -d "\n")

Reason: The project ‘Legacy Letters’ cannot be opened because it is in a future Xcode project file format (70). Adjust the project format using a compatible version of Xcode to allow it to be opened by this version of Xcode.
