CrossPlatform Hello World

Ch8Ex1CircleWeb

Swift: demo

Here is the workaround using repl.it
Circle on Repl.it
This is for use on iOS using XCode

---

// Declare our new Circle class
class Circle {
    var radius = 0.0
    
    init(radius: Double) { // Constructor
        self.radius = radius
        
    }
    var Area: Double{
        return 3.14*(radius*radius)
    }
    
    func getArea() -> Double {
        return 3.14*(radius*radius)
    }
    
    var Circumference: Double {
        return 2*3.14*radius
    }
    func getCircumference() -> Double{
        return 2*3.14*radius
    }
}



@IBAction func btnCalc(_ sender: UIButton) {

        let rad=Double(tbRad.text!);

        let circ1=Circle(radius:rad!);

        let a=String(format: "%.2f",circ1.getArea());

        let c=circ1.getCircumference();

        lblArea.text="Area: \(a)";

        lblCirc.text="Circumfrence: \(c)";

    }
