But I got warnings about "Unimplemented selector", which has nothing to do with "Multiple Definition Types" and is also just plainly not true, because these selectors were implemented, and were known to the compiler (via #import) as well.
The warning you were expecting comes from "strict selector matching" (Wstrict-selector-match), which is the 3rd of 3 selector-related build settings. The other two, in addition to what they say they're doing, also warn you if the return type or parameters are different bit widths, so 'int' vs. 'id' doesn't produce a complaint.
