as the title suggests, i cant run my (objective c) project in xcode after upgrading to Xcode 12. It is a Cocoapods project. It works fine when i deploy to my phone, but in the simulator I get three different errors for some reason. It complains about "missing module map" for a separate project i include: module map file '...(path)/Build/Products/Debug-iphonesimulator/MyLibraryProject/MyLibraryProject.imagemap' not found 2. It complains about a precompiled header: <unknown>:0: error: failed to emit precompiled header '(path)/Build/Intermediates.noindex/PrecompiledHeaders/myProject-Bridging-Header-swift2UGSYUUFRK85M-clang18QKMU0TXX4JD.pch' for bridging header '(path)/iphone/myProject/myProject-Bridging-Header.h' 3. Finally it complains about Not finding a bundle for a library that i use: error: Resource "(path)/Products/Debug-iphonesimulator/FCAlertView/FCAlertView.bundle" not found. Run 'pod install' to update the copy resources script. Again, i can build and deploy to my phone, and submit to TestFlight/Appstore, but if i pick an emulator it's crash and burn. I am not very knowledgeable about xcode inner workings, so if anyone has any pointers, i'd be *most* grateful.

Hello. I have an 12 year old app that still has some objective-c code in it. I have a place where i have a flip animation between 2 view controllers that looks like this: [UIView transitionFromView:origView toView:newViewController.view duration:0.5 options:UIViewAnimationOptionTransitionFlipFromRight completion:nil]; It has looked like this since 2012 at least. In our production release, it works prior to 26.1, but in 26.1 and 26.2, the flip is off-center and looks weird. it's like both edges flip the same way. It's a little bit hard to explain. If seen at least 2 other app store apps that i have installed behave this way too, from 26.1 and onwards. Anyone else seen this? Is there anything that can be done about it? Thankful for thoughts.

Hello, I created a lock screen widget for my app last year, as a widget app extension. It has worked fine, but I am working on a new release and it has stopped updating: It is not called anymore when I call WidgetCenter.shared.reloadTimelines(ofKind: "MyWidget"), and the preview screen is now blank when I add it on the lockscreen. I haven't touched anything related to the widget from what I know. The only things I can think of is that Xcode has updated my project files automagically, and I have updated cocoapods. I looked at the device logs, and found this: [...MyWidget] Failed to launch extension with error: Error Domain=com.apple.extensionKit.errorDomain Code=2 UserInfo={NSUnderlyingError=0x84b4d4410 {Error Domain=RBSRequestErrorDomain Code=5 UserInfo={NSLocalizedFailureReason=, NSUnderlyingError=0x84b45ea30 {Error Domain=NSPOSIXErrorDomain Code=111 UserInfo={NSLocalizedDescription=}}}}}. I have no idea what this is, hoping someone can come up with suggestions on where to look. I have looked at my git history but I can't find anything changed.

Please find below a complete app example. It has a button, when you press it, a local notification is created. However, the UnNotificationCenter.delegate is called twice, and I can't understand why. I am trying to move my project from Objective-C to Swift, and my similar code there doesn't get called twice, so I'm confused. Can anybody shine a light on this? Pointers appreciated. App: @main struct NotifTestApp: App { init() { UNUserNotificationCenter.current().delegate = NotificationReceiveHandler.shared configureUserNotifications() } var body: some Scene { WindowGroup { ContentView() } } private func configureUserNotifications() { UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .badge, .sound]) { granted, error in if granted { print("Notification permission granted.") } else if let error = error { print("Error requesting notification permissions: \(error)") } } } } class NotificationReceiveHandler: NSObject, UNUserNotificationCenterDelegate { static let shared = NotificationReceiveHandler() //>> THIS IS CALLED TWICE WHEN I PRESS THE BUTTON func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) { NSLog(">>> Will present notification!") completionHandler([.sound]) } } ///THE UI struct ContentView: View { var body: some View { VStack { Text("👾") .imageScale(.large) .foregroundStyle(.tint) Text("Notification test!") Text("When i press the button, will present is called twice!!").font(.footnote) .padding(10) Button("Create Notification") { createNotification( message: "This is a test notification", header: "Test Notification", category: "TEST_CATEGORY", playSound: true, dictionary: nil, imageName: nil) } .padding() .background(Color.blue) .foregroundColor(.white) .cornerRadius(8) } .padding() } } #Preview { ContentView() } private func createNotification(message: String, header: String, category: String, playSound: Bool = true, dictionary: NSDictionary? = nil, imageName: String? = nil) { let content = UNMutableNotificationContent() content.title = header content.body = message content.categoryIdentifier = category content.badge = NSNumber(value: 0) if let imageName = imageName, let imageURL = Bundle.main.url(forResource: imageName, withExtension: "png") { do { let attachment = try UNNotificationAttachment(identifier: "image", url: imageURL, options: nil) content.attachments = [attachment] } catch { print("Error creating notification attachment: \(error)") } } content.sound = playSound ? UNNotificationSound(named: UNNotificationSoundName("event.aiff")) : nil if let infoDict = dictionary { content.userInfo = infoDict as! [AnyHashable: Any] } let request = UNNotificationRequest(identifier: UUID().uuidString, content: content, trigger: nil) UNUserNotificationCenter.current().add(request, withCompletionHandler: nil) }

Hi, just got upgraded this morning and now I can't use my local Tomcat install as server for my apps. I can access it in safari using localhost, but not using my computers IP. I start it from terminal. I looked everywhere in settings, and searched online of course, but have been unable to find an answer. Anyone knows how I can fit it? Input appreciated.

(Also have a case ID, 9879068) We have an app that user use to check in/out from work for example. We have a button in-app do do this. Now I'm trying to add buttons to our widgets and our new live activity so that users don't have to open the app. It's crucial that the live activity and widgets always show the exact same state. Otherwise it'll look pretty bad if a user has both a live activity and a widget showin at the same time. However, we have noticed that sometimes, pressing the button in the live activity, running the app intent, will not always make the widget update (we call reloadAllTimelines()). The other way around, i.e. press the button on widget to update live activity always works. (they both call the same app intent) When running it in debug mode on a phone from Xcode, it always works, but when running it just on the phone it's unreliable. My first thought was, of course, that's related to the widget "budget", but according to the docs HERE, it should not be applied when interacting with a widget, calling an app intent. My question: HOW can I make my widget reliably refresh using an app intent invoked from a live activity?? I have a ready small project with simple buttons and trace labels that display this issue that I'm happy to supply to someone.

Hi, i have a separate question for the same widget here, so please look there for the source code. In the widget, you can see i have various print()-calls in the methods. On the simulator i can see the calls, however when i run on my phone, they are not visible anywhere. In xcode the log window closes (and opens up again if i run the app itself, not the extension), and i cannot find them in the console app either. Is this expected behavior or am i missing something? Thankful for pointers.

Basically, in my widget/live activity, I want to extract reusable views into a separate file with an isolated view and preview. Dummy example below. I cannot do it because it says "missing previewcontext". The only way I've found is to add the view to my main app target, but I don't want to clutter my main app wiews that only exist in my widgets if I can avoid it. Can this be done somehow? Thoughts appreciated. Dummy example (tried with and without "previewLayout": struct StatusActivityView: View { let status: UserStatusData var body: some View { VStack(alignment: .center) { Text("Dummy example") }.background(.blue).padding(5) } } @available(iOS 16.2, *) struct StatusActivityView_Previews: PreviewProvider { static var previews: some View { let status = WidgetConstants.defaultEntry() return StatusActivityView(status: status).previewLayout(.sizeThatFits) } }

Please consider simple example below. I am trying to put a timer in the upper right corner of a live activity. I am done, it works, but I'm trying to get the timer to look better. If I take a regular text, I can get it to align properly by adjusting the .frame(), , but for a text with a timer inside it, alignment is ignored from what I can see. Text("Hello").frame(width: 90, alignment: .trailing).border(.red) /*Text(timerInterval: timeRange, countsDown: false) .monospacedDigit().font(.subheadline).frame(width: 90, alignment: .trailing).border(.red)*/ } Is there any way to fix this? Right now, I have a fixed width so that HH:mm:ss will fit, but that doesn't look super great if it's just minutes and seconds for example, there's an empty block to the right

I am looking into a piece of old code where the mentioned method is called. + (bool)isLocationServicesEnabled { return [CLLocationManager locationServicesEnabled]; } I'm getting the classic "This method can cause UI unresponsiveness if invoked on the main thread. Instead, consider waiting for the -locationManagerDidChangeAuthorization: callback and checking authorizationStatus first." I have 2 questions: What is that error about, really? The locationServicesEnabled() has nothing to do with authorisation, it's just about the "location services" settings global on-off switch? (the authorisation check is .authorizationStatus) I don't understand why that call is such a big issue? It's just a setting? Why would that be so costly? Thankful for pointers! Have a good one

Hello, we have an app that has a case where the user can turn on a feature that starts a timer for a thing when they arrive at a specific location. Our app also has a live activity to show the timer. Naturally, we're trying to make our live activity to start counting when the geofence triggers, but we get ActivityAuthorizationError.visibility. If an activity is already running, it's possible to turn it off. So, our question is basically if there's any way to make the geofence trigger start our live activity? Thanks

Hello, I am updating my live activity for the new ios18 Smart Stack functionality. I got it working through the WWDC session (Bring your live activities to Apple watch). I'm doing supplementalActivityFamilies([.small]) and then a custom layout in the .small ActivityFamily However, any images I try to use in the Smart Stack just show up as grey squares. (it works on the phone live activity) I suspect it's because my app images are not moved over to the watch? Because I don't have a watch app and such no watch target? If anyone can help me understand if there's anything I can do in order to have a custom image show up on the smart stack, I'd be very grateful.

Hi, working on customising my live activity Smart Stack layout for ios18. A thing that is very frustrating is that I consistently looks different for me in the Xcode preview and on the actual watch. See attached screenshots below. The sizes are different, and italic doesn't work on the watch, for example. It makes it time-consuming and unpredictable, so I was wondering if this is a known issue or if I'm doing something wrong, and also can I do anything? thanks edit: this is the layout: var body: some View { VStack(alignment: .center, spacing:4) { HStack(alignment: .center) { IconView(resource: "n-compact-w", bgColor: Color.checkedIn, padding: 2, paddingRight: 6, paddingBottom: 6) .frame(maxWidth: 25, maxHeight: 25).aspectRatio(1, contentMode: .fit) Text("Checked Out") .font(.title3).bold() } Text(status.loc) .font(.headline) .multilineTextAlignment(.center) Text(FormatUtils.getFormattedDateTime(status.time)).font(.subheadline) .multilineTextAlignment(.center).italic() } }

I have been using the SCNetworkReachabilityGetFlags for 10+ years to inform users that their request won't work. In my experience this works pretty well although i am aware of the limitations. Now, i am looking into the NWPathMonitor, and i have one situation that i'm trying to. get my head around - it's asynchronous. Specifically, i am wondering what to do when my geofences trigger and i want to check network connectivity - i want to tell the user why the operation i'll perform because of the trigger couldn't be done. SO. say i start a NWPathMonitor in didFinishLaunchingWithOptions. When the app is booted up because of a geofence trigger, might i not end up in a case where my didEnterRegion / didExitRegion gets called before the NWPathMonitor has gotten its first status? The advantage here with SCNetworkReachabilityGetFlags, as i understand it, would be that it's synchronous? If i want to upgrade to nwpathmonitor, i guess i have to do a method that creates a nwpathmonitor, uses a semaphore to wait for the first callback, then contunues? Thoughts appreciated

I have a UIView that i create with a XIB. I then want to add it on top of a parent, take up the whole screen but use the safe area i have set up constraints for in the xib. I can add the view fine, but when i do, the safe area is ignored, and the view goes all the way to the top and bottom. The code i use (objective-c still sorry): (UIView *parent) MyViewController *newViewController = [[MyViewController alloc] initWithNibName:MY_VIEW_NIB_NAME bundle:nil]; [view setFrame:CGRectMake(0, 0, parent.bounds.size.width, parent.bounds.size.height)]; [parent addSubview:self.view]; In the Xib, i have the top and bottom constrained to SafeArea.top and bottom. It looks fine in the layout there. Any tips are appreciated.
