flutter build ios-framework runtime crashes on simulators with debug builds #46125
Description
The stub debug App.framework has an x86_64 architecture but links macOS's /usr/lib/libSystem.B.dylib. Crashes when loading on simulator
dyld: Library not loaded: @rpath/App.framework/App
Referenced from: /Users/.../Library/Developer/CoreSimulator/Devices/CB8FE155-8F9C-48EE-A8E7-773318A51146/data/Containers/Bundle/Application/C25C0857-CB0D-4050-9674-5799C61199CF/MyApp.app/MyApp

Building for iOS Simulator, but linking in dylib file (/Users/.../Projects/MyApp/Flutter/Debug/App.framework/App) built for macOS
We need to build the stub dylib specifically for the simulator.
