Issue Description:

I'm using SwiftUI and have a view that is an optional. Rather than getting a warning about using an optional or a compile error for it XCode failed to produce a diagnostic for it. I clicked the option to send bug report and now I'm here. Not even sure if this is the place for swiftui bugs but yeah. LMK how I can easily submit the project for further inspection.

If you can share a minimal example for the code the fails to produce the diagnostic or if the code is open source, you can attach it here. Or else you can file a bug report through feedbackassistant.apple.com and attach your code there.
