It seems Webpack can't discover aliased modules that relative-import other
aliased modules e.g. "ui/transition", aliased to
"ui/transition/transition.android", not discovering "./slide-transition"
which is aliased to "ui/transition/slide-transition.android.js"
It appears that `-[NSObject performSelector:]` returns a dummy value when calling a void method on the iOS Simulator, whereas it correctly returns `nil` on a device. Since `-[NSObject performSelector:]` is declared as returning `id`, the iOS runtime tries to marshal the dummy value to a JavaScript object and fails because the dummy value is not a valid Objective-C object.
The fix is to use `-[NSObject valueForKey:]` for non-void zero-parameter methods and `NSInvocation` for everything else.
