It seems that there are several problems: what happens to the first, and then why it happens under your navigation material.
I will start with the first problem.
His example uses Cocoapods, and it seems like he tried to attach the completed xcworkspace to simplify it, but that didn't help me either.
I would suggest installing Cocoapods and starting the pod installation yourself. All instructions on how to do this should be in this link.
After that, the thing will still not compile, because some block is trying to set the enumeration to something that is not a compile-time constant. Just go ahead and change the enumeration values ββto constants (should be 1000, 750, 250, 50 respectively for missing values) to run the example. If you use codes in production code, you will NEVER want to do this, but since this is an example of using obsolete modules, just find the path of least resistance here.
As for the content under the navigation bar, you probably have to guess with the setting of the CollectionView contentInsets . You can also just bind CollectionView to this header bit that you have, with autorun or frames.
