“show when run”

Hello,I have a background daemon which is launched by launchd at system startup. I need to show a notification window to reports some event occationally. My snippet is as follows.CFStringRef message = CFStringCreateWithCString(NULL, filePath, kCFStringEncodingUTF8); CFUserNotificationDisplayNotice( 3.0f, kCFUserNotificationStopAlertLevel | kCFUserNotificationNoDefaultButtonFlag, NULL, NULL, NULL, CFSTR(alert), message, NULL); CFRelease(message);The CFUserNotificationDisplayNotice returns 0, but no window shows up.I cannot find much information about how to use this API.Could anybody show me the correct way to show some UI from a daemon? Thanks!

I have an iOS 8 app. When I run it on iOS 9, the QLPreviewController I use to display files (PDFs, Office docs, etc) no longer works. Instead, it only shows a gray screen with the filename. I am running iOS 9 beta 5.Is anyone else seeing this behavior? Any known issues or workarounds?Thanks!

Is there a way to programmatically show a UIMenu on iOS on a double-tap event? I have an app that's been around for over a decade, so there are some UX patterns that I'm reluctant to mess around with. There is a view in my app with the following properties: Tapping the view once focuses it and brings it to the front Double-tapping it shows a view controller as a sheet, with several operations you can perform on that object Instead of the sheet, I'd like to move to context menus - they look better, and they're more familiar for users. Obviously, adding a context menu for long-press is straightforward (just use UIContextMenuInteraction). But there does not seem to be a way to show the context menu on double-tap. I've discovered that you can use UIButton with showsMenuAsPrimaryAction to show the menu on single-tap, but that doesn't quite work for me. My users expect a single tap to do something else (focus the view) and will be annoyed if single taps start showing men

Hi all, I am new to Xcode and I'm struggling with the output. I remember back in time there was a way to show the output on terminal rather than in the small box at the bottom right, but I can't find it anymore. Does anybody know how? Version 12.5.1 Mac OS Big Sur Programming in C

I converted a fbx file to USDZ using Reality Converted. This seemed to work and I can double click in the USDZ file and a Xcode view pops up and shows the file/object with out a problem. But when I go to Reality Composer and try to import this USDZ I can see it added to the import list under + (add) and I can see it drag to the scene, but when I release everything disappears and I see nothing in the scene. How can I figure out what happen. Is there a console view I can bring up. Is there a way to list all the objects in the scene?

Wondered if others are seeing this too and not sure where to post (will cross post in tvOS beta as well). Specifically I'm seeing that neither of my 2 ATV test units now show up in the Apple Remote app regardless of being on the same network as the iPhone. Anyone else seeing this ? Both ATV's and iPhone are running latest beta. Thanks
