@Alua-Kinzhebayeva any update on this?

[jwelton]

Can you give anymore details on this?

[ashwingattani]

@jwelton every time we open a PDF, the CPU usage goes straight up to 100%, sometimes even more. Similarly, the memory is not released once the PDF is closed, some internal variables keep references in memory and result in application crash for lower memory devices.

i add "self.collectionView?.register(PDFThumbnailCell.self, forCellWithReuseIdentifier: "Cell")" in ViewdidLoad method(PDFThumbnailCollectionViewController) . Then solve this problem but i don't kown why?

I confirm that by reusing the cel with the reuse identifier as @xiaomingstudent says the issue is fixed
