Presenter to coordinator communication

- [Instructor] Before we dive into our view controllers,…it looks like we have to correct this…so that it's not using the instance,…but it's using the class navigation coordinator.…Let's go ahead and jump into…our spy list view controller.…So all we're going to do is replace…some of those maker methods with…this navigation coordinator.…We'll come in here, we'll say,…weak var n: NavigationCoordinator.…We're making it weak, so that we don't have…any retention cycle of this coordinator…owning this view controller,…owning this coordinator.…

We'll just keep it weak and optional.…Again, we don't need…this detailViewControllerMaker method anymore.…The spyCellMaker method I'm going to keep in here…because I feel like it really is part of…the list, the cell is.…And it's really up to you and your team…where you draw those lines or those barriers.…Let's go ahead and remove this argument.…And, we'll actually just copy this piece here.…And then, instead of this signing now,…I'll say self.navigationCoordinator is equal to…the one passed in.…
