title: Get child class from parent
body: <p>I have a big issue in Swift programming. I am trying to get the name of child class from the parent. This is a sample example, what i want to do:</p>
  
  <pre><code>class Parent {
    class func sayHello() {
        let nameChildClass = //
        println("hi \(nameChildClass)")
    }
  }
  
  class Mother: Parent {
  
  }
  
  class Father: Parent {
  
  }
  
  Mother.sayHello()
  Father.sayHello()
  </code></pre>
  
  <p>I know there is some other way do to that, but i really need to it like that.</p>
