Adlai Holler 4a5fd32ad8 Add Nullability to a Few Headers
Summary:
I saw some `!` in the Swift example that we can remove 🙂

Same as I mentioned in my last PR, the iOS examples project can't be opened on my machine, but I believe I updated the examples to be compatible.
Closes https://github.com/Instagram/IGListKit/pull/626
