let handler = #selector(FaceView.changeScale(byReactingTo:))

Argument of '#selector' refers to instance method 'changeScale(byReactingTo:)' that is not exposed to Objective-C

This is not the same issue. The method, changeScale(byReactingTo:) has been crossed out in the intellisense. – Oct 23 '17 at 11:02
From which pod/framework this `FaceView` class is coming from? – Paulo Mattos Oct 23 '17 at 11:13

@DroidGuy You need to show us more context then; what defines the method `changeScale(byReactingTo:)`, and can you edit it? If not, you probably just want to use an `@objc` thunk that then forwards onto `changeScale(byReactingTo:)`. – Hamish Oct 23 '17 at 11:25
Sorry about not being more detailed. FaceView is simply a UIView Cocoa Touch Class. – Oct 24 '17 at 08:51
