In swift program 

creating a class using class keyword

{

    var a:String = "Apple"

    var b:String = "Orange"

}

//Now we are creating instance to the Fruits class in another class

class ViewController: UIViewController {

        super.viewDidLoad()

            let fruit = Fruits()

            print("fruit.a")//prints Apple

}
