I haven't worked with collection views a whole lot.
A client wants a horizontal collection view set up with paging enabled.
They want a single cell centered in the collection view, with the edges of neighboring cells peeking into the view to provide a visual cue that they can swipe to see other cells.
If I set up the collection view using paging and a default flow layout, as I page over each cell ends up shifted to the left a bit more.
I implement the UICollectionViewDelegateFlowLayout protocol's collectionView(_:layout:insetForSectionAtIndex:) method, I can set up section insets such that each cell is kept centered, but when I do that the neighboring cells don't appear, and ONLY the current cell is ever visible until you start scrolling.
I assume I need to do something with a custom flow layout, but I'm not sure what, exactly. Can somebody offer some guidance?
(I'm working in Swift 2.3, although I'm "bilingual", so answers in either Swift or Objective-C are fine.)
