It is now April 2020 and I too have run into this problem. The examples in the Building Lists and Navigation tutorial do not match the BuildingListsAndNavigation project files downloaded from the tutorial.
In the example in Section 2, Step 1 of the tutorial, the LandmarkRows.swift file is shown as being saved into "Landmarks Views" folder. That folder does not exist in the downloaded resource files. So where do I save it?
Also at the beginning of Section 1, Step 1 it mentions nothing about loading the BuildingListsAndNavigation -> StartingPoint -> Landmarks -> BuildingListsAndNavigation.xcodeproj so I am assuming that is what was needed in order to start with Step 1.
And finally, to complicate matters even worse, there isn't even a folder named "Landmark Views" anywhere in BuildingListsAndNavigation -> Complete -> Landmarks -> Landmarks. It is named "Supporting Views" which isn't shown anywhere in this tutorial.
It's like independent developers wrote the tutorial, others wrote the code, and no one verified the tutorial matches the example code and folder structure.
