Research direction

Start with the minimal reproduction using SwiftUI, ModelsDSTU2, and ModelsR4, and confirm the ambiguous Observation error when declaring an @Observable class. Trace the conflicting package declarations and verify that the reproduction compiles without the workaround of moving associated code into a separate extension file.

Description

bug

I think I'm going crazy here but after importing

import ModelsDSTU2
import ModelsR4

in a project it stops compiling with some obscure errors. From what I can make out, it seems the classes defined in the package clash with the SwiftUI @Observable macro:

/var/folders/rt/5jrx9dk91r17__4r2tm3m01w0000gn/T/swift-generated-sources/@__swiftmacro_6cardya13HKDataManager10ObservablefMe_.swift:1:26 'Observation' is ambiguous for type lookup in this context

A minimal reproduction of this error:

import SwiftUI
import ModelsDSTU2
import ModelsR4

@Observable class TestClass {}

The quickest work around has been to move all associated code to a separate file in an extension.
