Anonymous class in swift

Question

Is there an equivalent syntax or technique for Anonymous class in Swift? Just for clarification Anonymous class in Java example here - http://docs.oracle.com/javase/tutorial

Answer 1

No anonymous class syntax in Swift. But, you can create a class inside a class and class methods:

class ViewController: UIViewController {

    class anonymousSwiftClass {
        func add(number1:Int, number2:Int) -> Int {
            return number1+number2;
        }
    }

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.

        class innerSwiftClass {
            func sub(number1:Int, number2:Int) -> Int {
                return number1-number2;
            }
        }

        var inner = innerSwiftClass();
        println(inner.sub(2, number2: 3));

        var anonymous = anonymousSwiftClass();
        println(anonymous.add(2, number2: 3));
    }
}
