iOS 10.
I'm seeing some odd behavior where occasionally collection view cells are drawn on top of their section header view instead of behind it. When I use the view inspector in Xcode then I do, in fact, see the cells in front of the section header.
These are pretty generic cells that contain an image. The only thing special is that the image is loaded asynchronously and then set on the cells UIImageView in a completion block on the main thread.
Has anybody else run across this behavior before?
