I am experiencing an issue with a Mac Catalyst app for those on Catalina Mac OS X 10.15.7 (19H2026) with the Class UIMarkupTextPrintFormatter. The error experienced is that it is missing in the OS. I have used UIMarkupTextPrintFormatter in all previous versions of the app without issue and the developer documentation on this Class [https://developer.apple.com/documentation/uikit/uimarkuptextprintformatter] declares it is compatible with Mac Catalyst 13.1+ and I am building for a minimum target of 13.4. Does anyone have an idea of what is going on?

An update I have now even put a check on the code below to try to get around the issue Xcode 14.1(14B7) and I am still getting a crash on Catalina MacCatalyst 13 with the error

Termination Reason: DYLD, [0x4] Symbol missing

Application Specific Information:

dyld: launch, loading dependent libraries

Dyld Error Message:

Symbol not found: OBJC_CLASS$_UIMarkupTextPrintFormatter

   @available(iOS 14, macCatalyst 14, *)
        func printNote()  {
            let printInfo = UIPrintInfo(dictionary: nil)
            printInfo.jobName = noteTitle
            printInfo.outputType = .general
            printInfo.orientation = .portrait
            let formatter = UIMarkupTextPrintFormatter(markupText: htmlForSharing) ....

Has anyone else seen this behaviour
