I found the answer, and it's in Session 417 from 2014 WWDC "What's New in LLVM". If you find this code in a 3rd party library, such as Apsalar, updating to the latest version fixes it (probably because it's not distributed as a lib, ha). For an example of casting of these calls, see THObserversAndBinders library - I'm using it and noticed that the author updated the code, such as here:
