ios9 - AirPrint (UIPrintInteractionController) print warnings with iOS 9, swift 2, XCode 7 -


since updating newest xcode/swift 2/ios 9 keep getting warnings when trying use uiprintinteractioncontroller.

these warnings happen when have "print simulator" open. thought app made new single view app single uibutton simple code , still generates warnings. happens on both phone , ipad simulators

please help. it's driving me crazy, thank all

@ibaction func clicked(sender: anyobject) {      let printcontroller = uiprintinteractioncontroller.sharedprintcontroller()      let printinfo = uiprintinfo(dictionary:nil)     printinfo.outputtype = uiprintinfooutputtype.general     printinfo.jobname = "print job"     printcontroller.printinfo = printinfo      let formatter = uimarkuptextprintformatter(markuptext: "<b>hello world</b>")     formatter.contentinsets = uiedgeinsets(top: 72, left: 72, bottom: 72, right: 72)     printcontroller.printformatter = formatter      if uidevice.currentdevice().userinterfaceidiom == .phone {         printcontroller.presentanimated(false, completionhandler: nil)     }else{         printcontroller.presentfromrect(view.frame, inview: view, animated: false, completionhandler: nil)     } }

here warnings:

probably issue 

printcontroller.presentfromrect(view.frame, inview: view, animated: false, completionhandler: nil)

verify view rect presentfromrect

or else try with

[printcontroller presentanimated:yes completionhandler:nil];

this solution removed warnings code, try luck.

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
