Say you have an instance, and you want to call a class method, similar to objc where you could do something like self.class.insets.left. Use type(of: self).methodName()class Bargle { static func greeble() { print("Blargle greeble") } func oopack() { type(of: self).greeble() } } let bargle = Bargle() bargle.oopack()This will cause Blargle greeble
