1,949 PointsWhy am I getting a compile error?
I am getting the message "Bummer! Your code could not be compiled. Please click on "Preview" to view the compiler errors." But whenever I check preview, it doesn't show anything. Also, whenever I copy and paste into Xcode, there are no errors showing up. I'm very lost as to where the error is coming from. Any help is appreciative.
// Enter your code below
class Shape
{
var numberOfSides: Int
init(numberOfSides: Int)
{
self.numberOfSides = numberOfSides
}
}
let someShape: Shape

23,970 PointsThe problem is when you are creating an instance, it must include numberOfSides
class Shape {
var numberOfSides: Int
init(numberOfSides: Int) {
self.numberOfSides = numberOfSides
}
}
let someShape = Shape(numberOfSides: 4)
