In this vide at 4:30, you said "We automatically get a method with parameters for the stored properties in our class" when you tried to create coordinatePoint2 and xcode provided an autocomplete. As you were trying to create a constant with type Point, are you implying that the Struct is a method because the underlying Struct form is a function?

22,160 PointsSo that autocomplete stuff that shows when you are creating an object from a class (or struct or any other kind of type like this) is actually from one (or more) initializer methods.
Initializer methods are methods that are named init of which you can have more than one inside your type so that you can support different parameters coming in.
In the case in this video, your type did not have a method named init created. But the compiler, using that magic he mentions, has a "automatic" initializer in this case that it creates from the properties in your method.
This allows you to pass parameters in when you are creating a new object from your type and it will assign the values of these parameters to your properties (of the same name) inside the object as it is created.
Later you will learn to create your own init methods. That is lots of fun. :)
