The app review team must be bored today.

It's not the first time Apple has done this. Same issue was occurring for a while at least three years ago. Hopefully they'll fix it quickly this time.

(Humble apologies... I seem to have double-posted this question.)

Ignore my previous post. Mine was caused by a work around to a crash bug that appears to have since been fixed, such that now the work around causes a similar crash. I wonder if perhaps your issue may have been caused by the same bug, and has since disappeared in more recent versions of the OS? The work around was this: ` override func drawPrintFormatter(_ printFormatter: UIPrintFormatter, forPageAt pageIndex: Int) { //  WORK AROUND A CRASH BUG WHEN THERE ARE MULTIPLE UIPrintFormatters and pages //  See:  https://forums.developer.apple.com/thread/30009 var index = pageIndex if let printFormatter = printFormatter as? UIViewPrintFormatter { index = pageIndex - printFormatter.startPage; } return super.drawPrintFormatter(printFormatter, forPageAt:index); } `

Did you ever resolve this? I'm having exactly the same problem, except that the index is different in my error: index 18446744073709551615 beyond bounds [0 .. 0] (Which I believe is -1 equivalent in an unsigned integer form.) My stack trace is identical to yours as far as I can tell. It actually displays the preview in the print panel, and then crashes. If I only attempt to print a single item it succeeds, but crashes when I try to print more than one item. However, if I print multiple items all on the one page (startingAtPage: 0 for all of them), it prints successfully and does NOT crash (but then of course all the items are printed overlapping on top of each other on a single page and looks terrible).
