It crashes on the last line of
let previewSize = BaseChatTableViewCell.getPreviewSize(from: imageSize, isMediaFile)
self.filePreviewImageViewHeightConstraint?.constant = previewSize.height
self.filePreviewImageViewWidthConstraint?.constant = previewSize.width
where previewSize is a CGSize. I am unable to reproduce the crash, nor am I able to understand why it crashes there. Anyone got an idea what could cause a crash on setting a constant?
