My app has a PDFViewer utilizing QLPreviewController library. This has been working with none downside till the final month. Since then I have been getting a number of crashes with iOS 18. That is the stacktrace:

Checking this crash with XCode > organizer I haven’t got extra info, it is the identical stacktrace.
I am unable to reproduce the error domestically.
The one reference I’ve discovered a couple of comparable problem is with giant PDFs however in my case some crashes occurs with PDF not so giant, and then again the crash says setCanChangeCurrentPage and that is about altering the web page…
Anny clue of what’s occurring?
