iOS Object-Oriented Swift 2.0 Classes Instances of Classes

1,158 Points


Hey guys! Would be very glad if someone could explain me step by step how I should solve this task: "Let's get in some practice creating a class. Declare a class named Shape with a variable property named numberOfSides of type Int.

Remember that with classes you are required to write an initializer method.

Once you have a class definition, create an instance and assign it to a constant named someShape."

Thank you!

I would sincerely prefer to know what you've tried thus far that's failed so we can say what's going wrong. But here is my solution along with comments as explanations.

// Enter your code below
class Shape {       //declare the class Shape
  var numberOfSides: Int    //declare a variable to hold the number of sides of type int
  init (numberOfSides: Int) {   // initialize the number of sides of the shape
    self.numberOfSides = numberOfSides  // this sets the number of sides to the number of sides passed in by the creation of a new shape

let someShape = Shape(numberOfSides: 5)  //  this creates a new object of type Shape with 5 sides... aka a pentagon

Hope this helps, but if you have questions let me know! :smiley:
