Hello everyone! I'm having a problem with background tasks running in the foreground. When a user enters the app, a background task is triggered. I've written some code to check if the app is in the foreground and to prevent the task from running, but it doesn't always work. Sometimes the task runs in the background as expected, but other times it runs in the foreground, as I mentioned earlier. Could it be that I'm doing something wrong? Any suggestions would be appreciated. here is code: class BackgroundTaskService { @Environment(\.scenePhase) var scenePhase static let shared = BackgroundTaskService() private init() {} // MARK: - create task func createCheckTask() { let identifier = TaskIdentifier.check BGTaskScheduler.shared.getPendingTaskRequests { requests in if requests.contains(where: { $0.identifier == identifier.rawValue }) { return } self.createByInterval(identifier: identifier.rawValue, interval: identifier.interval) } } private func createByInterval(identifier: String, interval: TimeInterval) { let request = BGProcessingTaskRequest(identifier: identifier) request.earliestBeginDate = Date(timeIntervalSinceNow: interval) scheduleTask(request: request) } // MARK: submit task private func scheduleTask(request: BGProcessingTaskRequest) { do { try BGTaskScheduler.shared.submit(request) } catch { // some actions with error } } // MARK: background actions func checkTask(task: BGProcessingTask) { let today = Calendar.current.startOfDay(for: Date()) let lastExecutionDate = UserDefaults.standard.object(forKey: "lastCheckExecutionDate") as? Date ?? Date.distantPast let notRunnedToday = !Calendar.current.isDate(today, inSameDayAs: lastExecutionDate) guard notRunnedToday else { task.setTaskCompleted(success: true) createCheckTask() return } if scenePhase == .background { TaskActionStore.shared.getAction(for: task.identifier)?() } task.setTaskCompleted(success: true) UserDefaults.standard.set(today, forKey: "lastCheckExecutionDate") createCheckTask() } } And in AppDelegate: BGTaskScheduler.shared.register(forTaskWithIdentifier: "check", using: nil) { task in guard let task = task as? BGProcessingTask else { return } BackgroundTaskService.shared.checkNodeTask(task: task) } BackgroundTaskService.shared.createCheckTask()

This is my first post here. Please guide me, if I need to provide more information to answer this post. I write a simple application, that monitors GPS position (location). I followed Apple documentation for LiveUpdates: https://developer.apple.com/documentation/corelocation/supporting-live-updates-in-swiftui-and-mac-catalyst-apps My app can monitor location in foreground, background or it can completely stop monitoring location. Background location, if needed, is switched on when application changes scenePhase to .background. But it is in the foreground, that memory leaks occur (according to Instruments/Leaks. Namely Leaks points to the instruction: let updates = CLLocationUpdate.liveUpdates() every time I start location and then stop it, by setting updatesStarted to false. Leaks claims there are 5x leaks there: Malloc 32 Bytes 1 0x6000002c1d00 32 Bytes libswiftDispatch.dylib OS_dispatch_queue.init(label:qos:attributes:autoreleaseFrequency:target:) CLDispatchSilo 1 0x60000269e700 96 Bytes CoreLocation 0x184525c64 Malloc 48 Bytes 1 0x600000c8f2d0 48 Bytes Foundation +[NSString stringWithUTF8String:] NSMutableSet 1 0x6000002c4240 32 Bytes LocationSupport 0x18baa65d4 dispatch_queue_t (serial) 1 0x600002c69c80 128 Bytes libswiftDispatch.dylib OS_dispatch_queue.init(label:qos:attributes:autoreleaseFrequency:target:) I tried [weak self] in Task, but it doesn't solve the leaks problem and causes other issues, so I dropped it. Anyway, Apple doesn't use it either. Just in case this is my function, which has been slightly changed comparing to Apple example, to suit my needs: func startLocationUpdates() { Task() { do { self.updatesStarted = true let updates = CLLocationUpdate.liveUpdates() for try await update in updates { // End location updates by breaking out of the loop. if !self.updatesStarted { self.location = nil self.mapLocation = nil self.track.removeAll() break } if let loc = update.location { let locationCoordinate = loc.coordinate let location2D = CLLocationCoordinate2D(latitude: locationCoordinate.latitude, longitude: locationCoordinate.longitude) self.location = location2D if self.isAnchor { if #available(iOS 18.0, *) { if !update.stationary { self.track.append(location2D) } } else { // Fallback on earlier versions if !update.isStationary { self.track.append(location2D) } } } } } } catch { // } return } } Can anyone help me locating these leaks?

I created a build and in the info.plist "Bundle version string (short)" is set to "$(MARKETING_VERSION)". In the project settings the marketing version is set 5.0 and this shows in Testfight. When I submitted the app for review I set the app store version number to 3.3. I know the app will appear in the appstore as v3.3. Before I release this app I need to know: What number will be returned by "infoDictionary?["CFBundleShortVersionString"]"? 5.0 or 3.3?

I’m working with Swift and encountered an issue when using the contains method on an array. The following code works fine: let result = ["hello", "world"].contains(Optional("hello")) // ✅ Works fine However, when I try to use the same contains method with the array declared in a separate constant(or variable), I get a compile-time error: let stringArray = ["hello", "world"] let result = stringArray.contains(Optional("hello")) // ❌ Compile-time error The compiler produces the following error message: Cannot convert value of type 'Optional<String>' to expected argument type 'String' Both examples seem conceptually similar, but the second one causes a compile-time error, while the first one works fine. This confuses me because I know that Swift automatically promotes a non-optional value to an optional when comparing it with an optional value. This means "hello" should be implicitly converted to Optional("hello") for the comparison. What I understand so far: The contains(_:) method is defined as: func contains(_ element: Element) -> Bool Internally, it calls contains(where:), as seen in the Swift source code: 🔗 Reference contains(where:) takes a closure that applies the == operator for comparison. Since Swift allows comparing String and String? directly (String is implicitly promoted to String? when compared with an optional), I expected contains(where:) to work the same way. My Questions: Why does the first example work, but the second one fails with a compile-time error? What exactly causes this error in the second case, even though both cases involve comparing an optional value with a non-optional value? Does contains(_:) behave differently when used with an explicit array variable rather than a direct array literal? If so, why? I know that there are different ways to resolve this, like using nil coalescing or optional binding, but what I’m really looking for is a detailed explanation of why this issue occurs at the compile-time level. Can anyone explain the underlying reason for this behavior?

I'm trying to determine if it’s possible to detect when a user interacts with a Slide Over window while my app is running in the background on iPadOS. I've explored lifecycle methods such as scenePhase and various UIApplication notifications (e.g., willResignActiveNotification) to detect focus loss, but these approaches don't seem to capture the event reliably. Has anyone found an alternative solution or workaround for detecting this specific state change? Any insights or recommended practices would be greatly appreciated.

The flags like #if DEBUG ... endif are dependent on the Active Compilation Conditions. So if they say DEBUG the enclosed code block will be executed, otherwise not. Now I have the phenomenon that a #DEBUG block in a Package does not evaluate these conditions. It rather depends on the name of the configuration used to build. So if I build my app with Active Compilation Condition set to DEBUG, but the configuration name is something like App-Release, the DEBUG block in my Package is not added/executed. The ones which are directly in the project are added. Vice versa if the Compilation Condition say RELEASE but the configuration is called App-Debug the blocks in the Package are added to the compilation, but the ones in the project itself are not It suffices that the config name contains the word Debug for this to happen. E.g. the configuration App-Release-Debug (I know that this would be stupid, but it is for demonstrating purposes) will cause the Packages to include the DEBUG blocks. This happens no matter what you set in the Build Settings of the project and/or target. The Packages are added via GitHub/GitLab Source Control with SPM. Any ideas why this behaves like it does? It doesn't seem like it should...

I am working on a project for macOS where I am taking an AVCaptureSession's CVPixelBuffer and I need to convert it into a MTLTexture for rendering. On macOS the pixel format is 2vuy, there does not seem to be a clear format conversion while converting to a metal texture. I have been able to convert it to a texture but the color space seems to be off as it is rendering distorted colors with a double image. I believe 2vuy is a single pane color space and I have tried to account for that, but I am unaware of what is off. I have attached The CVPixelBuffer and The distorted MTLTexture along with a laundry list of errors. On iOS my conversions are fine, it is only the macOS 2vuy pixel format that seems to have issues. My code for the conversion is also attached. If there are any suggestions or guidance on how to properly convert a 2vuy CVPixelBuffer to a MTLTexture I would greatly appreciate it. Many Thanks Conversion_Logs.txt ConversionCode.swift

When an external keyboard is connected to the iPad, the software keyboard often becomes hidden and cannot be made to show again programmatically. Help! Is there a way to programmatically get the software keyboard to re-appear when an external keyboard is connected without clicking 'Show Keyboard' from the Keyboard Shortcuts menu-item button? Its corner-casey for sure, (with our own keyboard extension) we have a sub-view that is added to the software keyboard view under a certain use case. When the user has an external keyboard connected, everything is fine until the app is backgrounded. When the app is re-foregrounded the software keyboard often becomes hidden (what the user now sees is a keyboard shortcut menu-item group w/a keyboard button and a mic button.) This makes it impossible for the user to interact with the subview we added (because it is hidden), unless the user manually shows the software keyboard again by clicking "Show Keyboard" from the keyboard shortcut. The software keyboard view is still the 'firstResponder' (accepting key strokes, etc), we just cannot find a way to programmatically make it visible again. Sigh.

Hi everyone, I'm currently working on a project where I need to send multicast packets across all available network interfaces using Apple Network Framework's NWConnectionGroup. Specifically, the MacBook (device I am using for sending multicast requests, MacOS: 15.1) is connected to two networks: Wi-Fi (Network 1) and Ethernet (Network 2), and I need to send multicast requests over both interfaces. I tried using the .requiredInterface property as suggested by Eskimo in this post, but I’m running into issues. It seems like I can't create an NWInterface object because it doesn't have any initializers. Here is the code which I wrote: var multicast_group_descriptor : NWMulticastGroup var multicast_endpoint : NWEndpoint multicast_endpoint = NWEndpoint.hostPort(host: NWEndpoint.Host("234.0.0.1"), port: NWEndpoint.Port(rawValue: 49154)!) var connection_group : NWConnectionGroup var multicast_params : NWParameters multicast_params = NWParameters.udp var interface = NWInterface(NWInterface.InterfaceType.wiredEthernet) I get following error: 'NWInterface' cannot be constructed because it has no accessible initializers I also experimented with the .requiredInterfaceType property. Even when I set it to .wiredEthernet and then change it to .wifi, I am still unable to send requests over the Wi-Fi network. Here is the code I wrote: var multicast_params : NWParameters multicast_params = NWParameters.udp multicast_params.allowLocalEndpointReuse = true multicast_params.requiredInterfaceType = .wiredEthernet var ip = multicast_params.defaultProtocolStack.internetProtocol! as! NWProtocolIP.Options ip.disableMulticastLoopback = true connection_group = NWConnectionGroup(with: multicast_group_descriptor, using: multicast_params) connection_group.stateUpdateHandler = { state in print(state) if state == .ready { connection_group.send(content: "Hello from machine on 15".data(using: .utf8)) { error in print("Send to mg1 completed on wired Ethernet with error \(error?.errorCode)") var params = connection_group.parameters params.requiredInterfaceType = .wifi connection_group.send(content: "Hello from machine on 15 P2 on Wi-Fi".data(using: .utf8)) { error in print("Send to mg1 completed on Wi-Fi with error \(error?.errorCode)") } } } } Is this expected behavior when using NWConnectionGroup? Or is there a different approach I should take to ensure multicast requests are sent over both interfaces simultaneously? Any insights or suggestions would be greatly appreciated! Thanks in advance, Harshal

I'm trying to accomplish the features in this video where the child device requests permission from parent to control scren time. Then the parent can choose apps on the childs phone from their phone. Everything on the childs device is working exactly like in the video. However, on the parents phone, when the FamilyActivityPicker appears, it's only the apps on the parents phone and when an app is selected, nothing changes in the FamilyActivitySelection. I found this forum post describe the same issue I am having. I have a physical device logged in the child and a simulator running as the parent. Why can't I see the child's apps on the parents phone? Is it cause I'm running one of them on a simulator?

I would like to understand how to programmatically set the position of a cursor in a SwiftUI TextField. In UIKit this can be done using the selectedTextRange property, but I couldn't find a similar way to achieve this with pure SwiftUI. I want to figure out something like setCursorPosition (index:) - maybe by tracking the position in a @State or any other way. I understand that I can do this using UIViewRepresentable but I am looking for a pure SwiftUI solution and wanted to know if there is any.

I am working on a lung cancer scanning app in for iOS with a CoreML model and when I test my app on a physical device, the model results in the same prediction 100% of the time. I even changed the names around and still resulted in the same case. I have listed my labels in cases and when its just stuck on the same case (case 1) My code is below: https://github.com/ShivenKhurana1/Detect-to-Protect-App/blob/main/DetectToProtect/SecondView.swift I couldn't add the code as it was too long so I hope github link is fine!

Good day We developed a simple swift code to make the device ringing when a certain type of notifications arrives from our backend. This is the code: let phoneNumber = CXHandle(type: .generic, value: (self.userInfoForPluginCall!["data"] as! [String:Any]) ["caller"] as! String) callUpdate.remoteHandle = phoneNumber let configuration = CXProviderConfiguration(localizedName: "Trec Conf") configuration.maximumCallGroups = 1 configuration.maximumCallsPerCallGroup = 1 configuration.supportsVideo = false configuration.supportedHandleTypes = [.generic] configuration.iconTemplateImageData = UIImage(named: "callkit-icon")?.pngData() let callProvider = CXProvider(configuration: configuration) callProvider.setDelegate(self, queue: nil) callProvider.reportNewIncomingCall(with: callUUID!, update: callUpdate, completion: {error in}) We are noticing some problems on the call screen: on certain devices (iOS 18.4RC) the normal call screen appears and the user can answer or decline the call, on other devices (iOS 18.3, especially with dynamic island) only a phone icon appears in the upper right corner and no possibility to answer or deny call. Any idea on why we are encountering that behavior? Thanks

So I will summary an issue one of our clients has asked us on GitHub: https://github.com/pendo-io/pendo-mobile-sdk/issues/233 Project that is a custom framework that uses different SPM packages (one of them is Binary package), we have our main logic inside that framework and we have different targets that use this framework, everything works on the simulator, but running the app on the actual device provokes a crash saying "Binary framework was not found". We have like 20 other SPM packages that work fine, this is the first one we have an issue with. Please note I understand that SPM will not copy paste the Binary for the magic framework as it does for the apps so I suggested to embed it manually. So my question is what the best(easy) way to do it. Please refer to the following issue for more details: https://github.com/pendo-io/pendo-mobile-sdk/issues/233

I have created a custom class: class TarifsHeaderFooterView: UITableViewHeaderFooterView { …} With its init: override init(reuseIdentifier: String?) { super.init(reuseIdentifier: reuseIdentifier) configureContents() } I register the custom header view in viewDidLoad of the class using the tableView. Table delegate and data source are defined in storyboard. tarifsTableView.register(TarifsHeaderFooterView.self, forHeaderFooterViewReuseIdentifier: headerTarifsIdentifier) And call it: func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? { let view = tableView.dequeueReusableHeaderFooterView(withIdentifier: headerTarifsIdentifier) as! TarifsHeaderFooterView That works on iPhone (simulators and devices). But it crashes on any iPad simulator, as tableView.dequeueReusableHeaderFooterView(withIdentifier: headerTarifsIdentifier) is found nil. What difference between iPhone and iPad do I miss that explains this crash ? PS: sorry for the messy message. It looks like the new "feature" of the forum to put a Copy code button on the code parts, causes the code sections to be put at the very end of the post, not at the place they should be.

import SwiftUI struct ContentView: View { var body: some View { VStack { Button ("Button 1") { print ("Button 1"); } .keyboardShortcut("k", modifiers: .command) Button ("Button 2") { print ("Button 2"); } .keyboardShortcut("k", modifiers: .command) } } } I the above snippet, I have assigned the same keyboard shortcut (cmd +k) to 2 different buttons. According to the docs, if multiple controls are associated with the same shortcut, the first one found is used. How do I figure out if Button 1 would be found first during the traversal or Button 2 ? Is it based on the order of declaration? Is it always the case that Button 1 would be found first since it was declared before Button 2 ?

It takes a few seconds, sometimes a few minutes for records to be downloaded back from CloudKit when the user reinstalls the app, which leads users to thinking their data was lost. I would like to know if there’s any way to provide a visual feedback about the current CloudKit sync status so I can let users know their data is being in fact downloaded back to their devices.

My app sent a network request to the backend. The backend returns a 200, but the front end received a -1001 or -1005 NSURLError. Any clue why this could be happening?

How do I filter data using @Query with a Set of DateComponents? I successfully saved multiple dates using a MultiDatePicker in AddView.swift. In ListView.swift, I want to retrieve all records for the current or today’s date. There are hundreds of examples using @Query with strings and dates, but I haven’t found an example of @Query using a Set of DateComponents Nothing will compile and after hundreds and hundreds of attempts, my hair is turning gray. Please, please, please help me. For example, if the current date is Tuesday, March 4 205, then I want to retrieve both records. Since both records contain Tuesday, March 4, then retrieve both records. Sorting works fine because the order by clause uses period which is a Double. Unfortunately, my syntax is incorrect and I don’t know the correct predicate syntax for @Query and a Set of DateComponents. Class Planner.swift file import SwiftUI import SwiftData 
 @Model class Planner { //var id: UUID = UUID() var grade: Double = 4.0 var kumi: Double = 4.0 var period: Double = 1.0 var dates: Set<DateComponents> = [] init( grade: Double = 4.0, kumi: Double = 4.0, period: Double = 1.0, dates: Set<DateComponents> = [] ) { self.grade = grade self.kumi = kumi self.period = period self.dates = dates 
 } } @Query Model snippet of code does not work The compile error is to use a Set of DateComponents, not just DateComponents. @Query(filter: #Predicate<Planner> { $0.dates = DateComponents(calendar: Calendar.current, year: 2025, month: 3, day: 4)}, sort: [SortDescriptor(\Planner.period)]) var planner: [Planner] ListView.swift image EditView.swift for record #1 DB Browser for SQLlite: record #1 (March 6, 2025 and March 4, 2025)
