[swift-users] Swift 3 likes to tease me

This line (Swift 3):
	if a.responds(to: Selector(“viewControllers") )
creates this warning: Use '#selector' instead of explicitly constructing a 'Selector'

Ok. Following this advice I change it to:
	if a.responds(to: #selector(“viewControllers"))
and now get an error instead: Argument of ‘#selector' does not refer to an '@objc' method, property, or initializer

Why do I get punished for following Xcode’s advice?
