uikit - UICollectionView reloadSections (possibly?) creates memory leak

Question

I am using reloadSections(...) on my UICollectionView in order to update supplementaryViews (section header views). This works, but when I look at the memory graph I see that I now have twice as many cells in memory. Everything seems to be duplicated.

I noticed this because I saw a new cell being initialized, but deinit was never called. So I inspected with the Debug Memory Graph function.

Is this a bug in my code or is this simply some optimisation UIKit has?

I should perhaps add I have each cell type just once or twice, so there are many cell types in my collection view.
