Swift Sprawdź, czy klasa jest typu
class Animal {}
class Dog : Animal {}
class Cat : Animal {}
let c = Cat()
c is Dog // false
c is Cat // true
c is Animal // true
// In Swift => 3:
type(of: c) == Cat.self // true
type(of: c) == Animal.self // false
// In Swift 2:
c.dynamicType == Cat.self // true
c.dynamicType == Animal.self // false
