Code Final Assignment : Object Oriented Swift

Hello, here is my code for the final assignment for Object Oriented Swift. It says in my setter for the Square subclass that I cannot assign SideLength to itself. Isn't that what I'm supposed to do when initializing? Thank you

class Shape {
    let sides: Int
    let name: String

    init(sides: Int, name: String) {
        self.sides=sides
        self.name=name
    }
}
class Square: Shape {
    let sideLength : Double //Let
    var area: Double { //Computed thus VAR
        get {
           return sideLength * sideLength
        }
        set {
            sideLength = sqrt(newValue)
        }
    }
    init(name: String,
        sides: Int,
        sideLength: Double) {
        self.sideLength = sideLength
        super.init(sides: sides, name: name)
    }
    convenience init(sideLength: Double) {
        self.init(name: "Square", sides: 4, sideLength: sideLength)
    }
}

The only thing you'd have to change is let sideLength: Double to var sideLength: Double and your code should work.

Cheers thanks for taking the time! It worked!
