How to call Type Methods within an instance method

Question

Apple has a nice explanation of Type (Class) Methods, however, their example looks like this:

class SomeClass {     class func someTypeMethod() {         // type method implementation goes here     } } SomeClass.typeMethod() 

I see this exact same example parroted everywhere. My problem is, I need to call my Type Method from within an instance of my class, and that doesn't seem to compute.

I MUST be doing something wrong, but I noticed that Apple does not yet support Class Properties. I'm wondering if I'm wasting my time.

I tried this in a playground:

class ClassA {     class func staticMethod() -> String { return "STATIC" }      func dynamicMethod() -> String { return "DYNAMIC" }      func callBoth() -> ( dynamicRet:String, staticRet:String )     {         var dynamicRet:String = self.dynamicMethod()         var staticRet:String = ""  //        staticRet = self.class.staticMethod() // Nope //        staticRet = class.staticMethod() // No way, Jose //        staticRet = ClassA.staticMethod(self) // Uh-uh //        staticRet = ClassA.staticMethod(ClassA()) // Nah //        staticRet = self.staticMethod() // You is lame //        staticRet = .staticMethod() // You're kidding, right? //        staticRet = this.staticMethod() // What, are you making this crap up? //        staticRet = staticMethod()  // FAIL          return ( dynamicRet:dynamicRet, staticRet:staticRet )     } }  let instance:ClassA = ClassA() let test:( dynamicRet:String, staticRet:String ) = instance.callBoth() 

Does anyone have a clue for me?

Answer 1

var staticRet:String = ClassA.staticMethod() 

This works. It doesn't take any parameters so you don't need to pass in any. You can also get ClassA dynamically like this:

Swift 2

var staticRet:String = self.dynamicType.staticMethod() 

Swift 3

var staticRet:String = type(of:self).staticMethod()
