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!

Hi I would like to show the PhotosPicker programatically the same way we can do with sheet(isPresented: Binding) and fullScreenCover(isPresented: Binding), i.e. I would like: photosPicker(isPresented: Binding, selectedItem: Binding). This would allow me to have multiple buttons that show the picker and would make all my code that shows sheets consistent, thanks for reading.

I just upgraded to Xcode 12.4, created a project using the app template, without SwiftUI, I chose Storyboard instead. I placed a small image on the LaunchScreen.storyboard, and an NSLog output in my ViewController. When I run the app on the simulator, the LaunchScreen does not, show, and I do get my NSLog output. So I know the app is running. When run this bare app on my physical iPhone X...I do get the launch screen. So I opened a game app I started under Xcode 11.x. It will show the LaunchScreen on both simulator and my device. I've checked that Launch screen interface file base name is set to LaunchScreen in Info.plist. It's also set under App Icons and Launch Images. Is this some bug?

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

Is there any way, in Instruments, to figure out what allocations were deallocated in an interval? I'd like to highlight a section of the allocations timeline, and then see only the blocks that were deallocated during that interval (for bonus points, show only blocks that were allocated before that interval, but deallocated during that interval).I don't see an obvious way to do this. Thanks!
