How to get class of instance and call class function in Swift 4?

Question

In Objective-C, it was simple to get the class of an instance and call class methods on it. How do you do this in Swift 4?

e.g.

MyObject * obj = [[MyObject alloc] init];
[[obj class] someClassMethod];

Answer 1

You can use the type(of) method to get the class of an object, and use this to call a class method on it.

class MyObject {
  static func someClassMethod() {

  }
}
let obj = MyObject()
type(of: obj).someClassMethod()
