Try to compile MyFrameworkC. It will fail with

🛑 MyFrameworkB-Swift.h: Module 'MySwiftLibrary' not found

There are 3 XCode frameworks and one SPM library. The dependency graph is simply:

MyFrameworkC -> MyFrameworkB -> MyFrameworkA -> MySwiftLibrary

• MySwiftLibrary declares a single @objc public protocol and that's it.

• MyFrameworkA is empty.

• MyFrameworkB imports MySwiftModule and defines a public @objc class that conforms to the protocol declared in MySwiftLibrary.

• MyFrameworkC simply attempts to import MyFrameworkB.
