isMemberOfClass in Swift

Question

The keyword is is equivalent to isKindOfClass.

But I am unable to find what is equivalent of isMemberOfClass in swift.

Note: My question is not about the difference between isKindOfClass or isMemberofclass rather the question is about what is the equivalent of isMemberofClass in Swift

somebody please clarify

Answer 1

You are looking for type(of:) (previously .dynamicType in Swift 2).

Example:

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
