Answer 1

It’s not available in Catalyst, despite what the docs say.

You could explore using an AppKit alternative (QLPreviewPanel), but you’ll have to do some hacking to get it to work from a Catalyst app: https://stackoverflow.com/a/32814132/1601849

If you want to leave compatibility with OSX 10.5, you can do this check:

if UIDevice.current.systemName == "Mac OS X" {
   let version = Int (UIDevice.current.systemVersion.prefix (2)) ?? 10
   if version > 10 {
      self.documentInteractionController = [UIDocumentInteractionController interactionControllerWithURL:targetURL];
   } else {
      //do something
   }
} else {
   self.documentInteractionController =[UIDocumentInteractionController interactionControllerWithURL:targetURL];
