it would be nice if xcode project generated by qmake is debug/release

When you run qmake with Qt 6.2.4 on iOS, there is a generated Xcode project in the build directory. Unfortunately generated xcode project is always have debug build configuration even if qmake is run for release.
Steps to reproduce:
1. Create a generic Qt Quick iOS example app with Qt 6.x
2. Change to release build configuration.
3. Run qmake.
4. Open the generated Xcode project in Xcode 12.x.
5. Open and edit the only scheme
6. In the build section (see screenshot), notice the build configuration is debug. Expectation is since build configuration was for release, xcode project should also be release.
