You can assign a grade for the first attempt on the Grade Assignment page. If the override identifier is used with a member function, the compiler makes sure that the member function exists in the base class, and also the compiler restricts the program to compile otherwise.

The reason this became an error is that in Swift 4, a lot of properties that translated from Obj-C (in the SDK) to Swift as parameterless functions were fixed to translate as properties. Do we update the coding style every time some random new tools prefer a different style? Overhead of creating a new class. That will show you what's different about the correct one. Many of these which had been overlooked before were fixed in Swift 4. The programmer's intentions can be made clear to the compiler by override.
