Unstable behavior of xcodebuild -showdestinations

Hi, I am having an issue with xcodebuild -showdestinations command.

Steps to reproduce:

1. Create a new iOS application project in Xcode or use an existing one.
2. Navigate to this project in a terminal.
3. Run xcodebuild -project 'your-project-name.xcodeproj' -scheme 'your-scheme' -showdestinations

What I expect: All destinations available in the Xcode UI should be listed.

What I get: It depends. For new projects, I consistently get only generic platform destinations and my connected physical device.

When I run the same command on an older project, I sometimes see all the expected destinations. It seems to be a roughly 50/50 chance between the two outcomes.

Is there a way to get consistent results from xcodebuild -showdestinations? What can I do to ensure all destinations are listed reliably?

Here is a more detailed log and a screenshot:
