Unlike value types, if we assign the reference type to another object they will point to the same object. Changing any of them will affect the contents of the other one too. If you want to follow along with me, you can find the project in the Exercise Files folder Chapter three, theta three, begin. I add the new playground page called Cloning Reference Types. And let's rename the current one to Cloning Value Types. Let's remove the boilerplate code. This time, I'll declare a class instead of a structure. class. NameClass. And add the same properties, firstName and lastName of type String. Actually, we can go and copy them from here.
