SOLVED: Calling functions

	@K-Aje108 Sep '20 Why is it so that some functions do not need to be called? For example, when we define the data of a tableview, we define the function cellforrowat, but we do not need to call it, why is this? 3
	@roosterboy HWS+ Sep '20 Those are functions that the system calls. We supply the behavior that we want to happen when the system calls those functions. 4
	@nemecek-filip Sep '20 For clarification I would add that in this case for `cellForRowAt` and other TableView methods it is a `TableView` that calls your functions. Since you told the `TableView` your class is its delegate and dataSource and conformed to the protocols. This means that your class needs to have these required methods implemented and `TableView` can call them. You can google something like: "swift delegate pattern" to learn more. 4
