Creating a class or structure

We use the same syntax to define classes and structures. The only difference is we define a class using the class keyword, and a structure by using the struct keyword. Let's look at the syntax used to create both classes and structures:

class MyClass {
  // MyClass definition
}

struct MyStruct {
  // MyStruct definition
}

When we name a new type, we want to use the standard naming convention set by Swift where the name is in camel case, with the first letter being uppercase. Any method or property defined within the class or structure should also be named ...
