I have a problem with debuging crash log. I have tried debuging it in Xcode, but it is not pointing to any line of code. I don't know how to debug it. It crashed only on iPad (It crashed to some user in production). I think it is regarding PrintKit on thread 0. Can please someone help me? Thanks in advance
Code for displaying PrintController:
if UIPrintInteractionController.canPrint(pdfURL) {
let printInfo = UIPrintInfo(dictionary: nil)
printInfo.jobName = pdfURL.lastPathComponent
printInfo.outputType = .general
let printController = UIPrintInteractionController.shared
printController.printInfo = printInfo
printController.showsNumberOfCopies = false
printController.printingItem = pdfURL
printController.present(animated: true, completionHandler: nil)
}
