NS_REFINED_FOR_SWIFT is a macro that helps you write “swifty” API for objective-c code.
In the header file, you tag the method declaration with this macro, and in a swift extension, you write a swift implementation that uses it. This method prepends two underscores (
__myMethod(_: whatever:)) to most methods, though in the case of initializers, it appends to the first argument label.
NS_SWIFT_NAME is a macro that lets you specify the swift name for an objective-c method.
In the header file, you tag the method declaration with this macro, giving it the swift method name as it’s argument, e.g.:
-setFoo:(Foo *)foo NS_SWIFT_NAME(set(foo:));
