Xcode cloud builds fail with missing ObservableUserDefaultMacros target

[jnewland]

Adding this project as a dependency to my project causes it to fail its Xcode cloud build:

Target 'ObservableUserDefaultMacros' must be enabled before it can be used.

I'm not yet sure if there's a build setting I can use to workaround this; if I find one I'll share it here and close the issue.
