Minimal repro

I've found that strict selector matching (-Wselector) behaves differently with
@required and @optional protocol methods.

The minimal repro file shows this difference.

I would prefer -Wselector to not warn in either case. This affects my project
because I want the benefit of selector matching without triggering false
positive warnings when using required protocols.

edit: This is about -Wselector, not 'strict selector matching' as mentioned above.
