If a swift module is built from sources and then integrated as a prebuilt .framework, previously generated .swiftmodule is still visible to swiftc (e.g via some other target that is still built from sources in a module) -> the historical version is always used, even the new one is correctly exposed via apple_static_framework_import.

- To emulate new version, MyModule.framework has new API - align it in Sources/Parent.swift (comment out Step 1)
