is there any change in application background to foreground transition,as we are facing issue of broken connection for latest iOS 18.3?

when opening Main.storyboard, all screens turn black, XCode freezes, and then closes. I am adding the font according to this guide. I'm trying to add Inter-VariableFont_opsz,wght.ttf of the https://fonts.google.com/specimen/Inter

Hello, I am encountering an issue with .refreshable(action:) in ScrollView. The refresh action works as expected when performing a pull-to-refresh. However, if I put the app in the background while the refresh operation is in progress, the refresh indicator remains visible on the screen when I return to the foreground and does not disappear. Once I interact with the ScrollView after returning to the foreground, the refresh indicator disappears, and the functionality itself is not affected. I initially attempted to resolve this issue by triggering a view redraw when scenePhase changes. However, since my app presents the SwiftUI view using UIHostingController, the scenePhase from the environment does not seem to function correctly. This issue occurs on iOS 17.1 but does not appear on iOS 16.1.1. Is there a known way to resolve this unexpected behavior? Below is a simplified sample code (some parts are omitted): struct MyView: View { @StateObject private var model: MyModel var body: some View { ScrollView { // My ContentViews... } .refreshable { do { try await self.model.refresh() } catch { // Handle error } } } } @MainActor final class MyModel: ObservableObject { // === Some Code === func refresh() async throws { let data = try await self.fetchData() self.data = Array(OrderedSet(data)) } } I apologize for any mistakes in my English, as I am using a translation tool. Thank you in advance for your help! Best regards,

I have an iPhone app which relies heavily on TCP/IP communication in the local network. Therefore, the application starts a server socket and accepts incoming connections. This worked flawlessly for a long time and we had no problems with this. Problem In the last days however, we observed that for some iPhones with the server role other devices cannot connect to the server of our app. The server does not accept incoming connections on the devices IP address and the client times out. Environment Both iPhones (the server and the client) are in the same network with 192.168.1.0 address range and 255.255.255.0 subnet mask. The server has the IP 192.168.1.11 and the client has 192.168.1.22. This is a normal home WiFi network with no special firewall rules. Both devices have mobile data disabled and the "access local network" permission is granted. The server socket is bound to all interfaces (0.0.0.0). More technical symptoms When the server iPhone is in this faulty state, it seems like it somehow has two ip addresses: 192.168.2.123 and 192.168.1.11 The WiFi preferences show the (correct) .1.11 ip address. The Apps however see the (wrong) .2.123 ip address. I cannot explain where the other ip address comes from and why the device thinks it has this ip address. I've collected interface diagnosis information on a faulty iPhone and it listed the following interfaces and IPs: en0 -> 192.168.2.123 lo0 -> 127.0.0.1 pdp_ip0 (cellular) -> 192.0.0.2 pdp_ip1 to pdp_ip6 (cellular) -> -/- ipsec0 to ipsec6 (vpn) -> -/- llw0 (vpn) -> -/- awdl0 -> -/- anpi0 -> -/- ap1 -> -/- XHC0 -> -/- en1 and en2 (wired) -> -/- utun0 to utun2 (vpn) -> -/- The correct ip of the device is not listed anywhere in this list. A reboot helped to temporarily fix this problem. One user reported the same issue again a few hours later after a reboot. Switching off WiFi and reconnecting does not solve the problem. This issue occurred on several iPhones with the following specs: iOS Version 18.1.1, 18.3.1 iPhone 13 Pro, iPhone 13 Pro Max, iPhone 15 Pro The problem must be on the server side as the client can successfully connect to any other device in the same network. Question(s) Where does this second IP come from and why does the server not accept connections to either ip even though it is bound to 0.0.0.0? Are there any iOS system settings which could lead to this problem? (privacy setting, vpn, ...) What could be done to permanently fix this issue?

Hi everyone, I am experiencing an issue where I am unable to sign in to my Apple ID within Xcode. Even after updating my password and ensuring that all my credentials are correct, I continue to receive an "Incorrect username or password" error. However, I can successfully log in to Apple Developer Portal, iCloud, and Apple ID settings using the same credentials. Steps I've Taken to Resolve the Issue: Updated Software I have updated macOS Sequoia and Xcode to the latest versions. I have also verified that my Apple Developer certificates are up to date. Tried Resetting Authentication in macOS I removed all related entries for Xcode, Apple ID, and Developer from Keychain Access. Logged out of my Apple ID from System Settings and restarted my Mac. Logged back in and retried signing in to Xcode. Checked Authentication & Security Settings I verified that two-factor authentication (2FA) is enabled. Tried appending the verification code directly to the password when logging into Xcode. Checked Xcode Developer Directory Ran sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer Verified using xcode-select -p, which correctly pointed to the Xcode Developer directory. Tried Resetting Developer Tools Removed and reinstalled Command Line Tools (xcode-select --install). Accepted the Xcode license agreement (sudo xcodebuild -license). Reinstalled Xcode Completely uninstalled Xcode using sudo rm -rf /Applications/Xcode.app and reinstalled it from the Mac App Store. Problem Summary: Xcode does not recognize my Apple ID credentials, despite them being correct. I can successfully log in to Apple’s web services, but not to Xcode. I have already attempted multiple fixes, including resetting keychain entries, reinstalling Xcode, and verifying system configurations. I would appreciate your guidance on resolving this issue, as I need access to my Apple Developer account within Xcode to continue working on my app. Thank you for your support.

I have a view with some buttons, and add 2 gestures using simultaneously. My app works well when built with XCode less than 16, or run on iOS less than 18.0. Example code is below: VStack(spacing: 0) { Button { print("button tapped") } label: { Rectangle() .foregroundColor(.red) } .frame(height: 100) } .gesture( DragGesture(minimumDistance: 0) .onEnded { value in print("single tap") } .simultaneously(with: TapGesture(count: 2).onEnded { print("double tap") } ) ) .frame(width: 200, height: 200) .border(Color.purple) I expect the action on Button should be recognized and print out button tapped, but only single tap and double tap are recognized

Hello, We are experiencing slow launch time indicators in our performance monitoring tools(Crashlytics/DataDog/Xcode), and trying to understand what is the best approach to reduce it. Currently, cold launch takes ~900ms on iPhone 16 Pro , but ~2s on iPhone 11. Profiling app launch detected that most of the time is spend on loading the libraries. Our app is massive, we use a total of ~40 3rd parties libraries + 10 internal libraries. We enabled the "mergeable libraries" XCode new feature however the app launch is as written above. We also postponed some of the work in didFinishLaunch, which help a bit... But maybe we are trying to achieve the impossible? Could it be that large apps just can't reach the golden 500ms goal? Currently we are trying to create an "umbrella" library for all the third parties in order to force them to become part of the mergeable libraries. We would like to know if, are we on the right track?

The example database/server provided by Apple for Live Caller ID contains a hardcoded database with a tiny number of pre-defined numbers. However, its not expected to be representational of an live real world usage server. But the question is how can that be accomplished if its a requirement that the data be KPIR encrypted? In real world scenarios, the factors that effect whether a number should be blocked or not are continually changing and evolving on a minute-by-minute basis and new information becomes available or existing information changes. If the database supports tens of millions or hundreds of millions of constantly changing phone numbers, in order to meet the requirements of the Live Caller ID being KPIR encrypted, that would imply the database has to re-encrypt its database of millions endlessly for all time. That seems unfeasable and impractical to implement. Therefore how do the Apple designers of this feature envisage/suggest a real-world server supporting millions of changing data should meet the requirement to be KPIR encrypted?

I ran into a problem. When using Storekit1 to purchase an SKU, the user payment was successful, but StoreKit1 did return paymentCancelled to my App. I would like to know under what circumstances this problem may occur? How do I fix it? Thank you

My iPhone 11 has iOS 18.4 Beta and my new iPhone 16e isn’t supported for iOS 18.4 Beta (for now) and is on iOS 18.3.1 Beta. If anyone knows when it’ll be supported please let me know.

I am using NSPersistentCloudKitContainer and I decided to add a property to an entity. I accidentally ran try! container.initializeCloudKitSchema(options: []) while using the production container in Xcode (com.apple.developer.icloud-container-environment) which throw a couple of errors and created some FAKE_ records in my production container. So I changed to my development container and ran the try! container.initializeCloudKitSchema(options: []) and now it succeeded. After that I cleaned up the FAKE_ records scattered in production container but in Xcode when I'm running I now get these logs in the console (and I can't seem to get rid of them): error: CoreData+CloudKit: -[NSCloudKitMirroringDelegate _importFinishedWithResult:importer:](1398): <PFCloudKitImporter: 0x300cc72c0>: Import failed with error: Error Domain=NSCocoaErrorDomain Code=4864 "*** -[NSKeyedUnarchiver _initForReadingFromData:error:throwLegacyExceptions:]: incomprehensible archive (0x53, 0x6f, 0x6d, 0x65, 0x20, 0x73, 0x61, 0x6d)" UserInfo={NSDebugDescription=*** -[NSKeyedUnarchiver _initForReadingFromData:error:throwLegacyExceptions:]: incomprehensible archive (0x53, 0x6f, 0x6d, 0x65, 0x20, 0x73, 0x61, 0x6d)} error: CoreData+CloudKit: -[NSCloudKitMirroringDelegate recoverFromError:](2310): <NSCloudKitMirroringDelegate: 0x302695770> - Attempting recovery from error: Error Domain=NSCocoaErrorDomain Code=4864 "*** -[NSKeyedUnarchiver _initForReadingFromData:error:throwLegacyExceptions:]: incomprehensible archive (0x53, 0x6f, 0x6d, 0x65, 0x20, 0x73, 0x61, 0x6d)" UserInfo={NSDebugDescription=*** -[NSKeyedUnarchiver _initForReadingFromData:error:throwLegacyExceptions:]: incomprehensible archive (0x53, 0x6f, 0x6d, 0x65, 0x20, 0x73, 0x61, 0x6d)} error: CoreData+CloudKit: -[NSCloudKitMirroringDelegate _recoverFromError:withZoneIDs:forStore:inMonitor:](2620): <NSCloudKitMirroringDelegate: 0x302695770> - Failed to recover from error: NSCocoaErrorDomain:4864 Recovery encountered the following error: (null):0 error: CoreData+CloudKit: -[NSCloudKitMirroringDelegate resetAfterError:andKeepContainer:](610): <NSCloudKitMirroringDelegate: 0x302695770> - resetting internal state after error: Error Domain=NSCocoaErrorDomain Code=4864 "*** -[NSKeyedUnarchiver _initForReadingFromData:error:throwLegacyExceptions:]: incomprehensible archive (0x53, 0x6f, 0x6d, 0x65, 0x20, 0x73, 0x61, 0x6d)" UserInfo={NSDebugDescription=*** -[NSKeyedUnarchiver _initForReadingFromData:error:throwLegacyExceptions:]: incomprehensible archive (0x53, 0x6f, 0x6d, 0x65, 0x20, 0x73, 0x61, 0x6d)} error: CoreData+CloudKit: -[NSCloudKitMirroringDelegate _requestAbortedNotInitialized:](2198): <NSCloudKitMirroringDelegate: 0x302695770> - Never successfully initialized and cannot execute request '<NSCloudKitMirroringExportRequest: 0x303a52d00> 548CB420-E378-42E5-9607-D23E7A2A364D' due to error: Error Domain=NSCocoaErrorDomain Code=4864 "*** -[NSKeyedUnarchiver _initForReadingFromData:error:throwLegacyExceptions:]: incomprehensible archive (0x53, 0x6f, 0x6d, 0x65, 0x20, 0x73, 0x61, 0x6d)" UserInfo={NSDebugDescription=*** -[NSKeyedUnarchiver _initForReadingFromData:error:throwLegacyExceptions:]: incomprehensible archive (0x53, 0x6f, 0x6d, 0x65, 0x20, 0x73, 0x61, 0x6d)}

Has anyone had any issues with outlook since 18.4 the mail app has consistently been asking for me to re-enter my email password, for some reason it’s not storing it and just asked again

A simple view has misaligned localized content after being converted to an image using ImageRenderer. This is still problematic on real phone and TestFlight I'm not sure what the problem is, I'm assuming it's an ImageRenderer bug. I tried to use UIGraphicsImageRenderer, but the UIGraphicsImageRenderer captures the image in an inaccurate position, and it will be offset resulting in a white border. And I don't know why in some cases it encounters circular references that result in blank images. "(1) days" is also not converted to "1 day" properly.

How many 32-bit variables can I use concurrently in a single thread of a Metal compute kernel without worrying about the variables getting spilled into the device memory? Alternatively: how many 32-bit registers does a single thread have available for itself? Let's say that each thread of my compute kernel needs to store and work with its own array of N float variables, where N can be 128, 256, 512 or more. To achieve maximum possible performance, I do not want to the local thread variables to get spilled into the slow device memory. I want all N variables to be stored "on-chip", in the thread memory space. To make my question more concrete, let's say there is an array thread float localArray[N]. Assuming an unrealistic hypothetical scenario where localArray is the only variable in the whole kernel, what is the maximum value of N for which no portion of localArray would get spilled into the device memory? I searched in the Metal feature set tables, but I could not find any details.

Hello, I would like to ask if there is any possibility to invoke the Apple Sysdiagnose via an API call. I cannot find any API reference for Sysdiagnose. I am aware only about the manually invocation. https://it-training.apple.com/tutorials/support/sup075/ However, this is pretty annoying since a reproduction of a hunted bug takes several hours, so I am looking for the way how to invoke Sysdiagnose from our code.

Hi Folks, starting with iOS18 and using Xcode16, accessing fetchedProperties results in an error. I identified the issue to occur as soon as the initialization of a fetched property with external binary data storage starts. Console output during debugging: *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'This expression has evaluation disabled' *** First throw call stack: [...] libc++abi: terminating due to uncaught exception of type NSException Console output when trying to "print" the item via the contact menu of the debugger: Printing description of variable: error: error: Execution was interrupted, reason: internal ObjC exception breakpoint(-6).. The process has been returned to the state before expression evaluation. Message from debugger: killed The identical code works with iOS before iOS 18 (same for iPadOS 18). Does anyone observed a similar issue and figured out a solution already? Cheers, folox

Hello fellow developers, My app has been in App Store review for more than three months, and I have received very limited communication from Apple. App Review responded once, stating that they need more time, but no further updates have been provided. Developer Support only gives the same generic response that the review is still in progress. Two weeks ago, I resubmitted the app, but it remains in review with no response from either App Review or Developer Support. I also requested an expedited review, but nothing has happened. At this point, I’m unsure what else I can do to move the process forward. Has anyone else experienced such long review times? Any advice on how to escalate this situation? Thanks in advance for any help!

I am integrating per-app VPN functionality into an iOS app using Wireguard. Chrome is designated as a per-app application for this purpose. However, upon opening Chrome, the VPN icon appears in the notification bar, but there is no internet connection within the Chrome browser. I have verified this behavior with OpenVPN, and it works correctly. While I am familiar with the MDM payload and how to implement per-app VPN, my primary concern is understanding why per-app VPN functionality is not functioning as expected with WireGuard. An observation we made in the server-side logs is the message: "wireguard: wg0: Packet has incorrect size from peer 1"

I have currently created an app which contains an upload button which when clicked upload health data using HealthKit to an AWS S3 bucket. Now I want to implement an automatic file upload mechanism which would mean that the app is installed and opened just once - and then the upload must happen on a schedule (once daily) from the background without ever having to open the app again. I've tried frameworks like NSURLSession and BackgroundTasks but nothing seems to work. Is this use case even possible to implement? Does iOS allow this? The file is just a few KBs in size. For reference, here is the Background Tasks code: import UIKit import BackgroundTasks import HealthKit class AppDelegate: NSObject, UIApplicationDelegate { let backgroundTaskIdentifier = "com.yourapp.healthdata.upload" func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -&gt; Bool { // Register the background task BGTaskScheduler.shared.register(forTaskWithIdentifier: backgroundTaskIdentifier, using: nil) { task in self.handleHealthDataUpload(task: task as! BGAppRefreshTask) } // Schedule the first upload task scheduleDailyUpload() return true } // Schedule the background task for daily execution func scheduleDailyUpload() { print("[AppDelegate] Scheduling daily background task.") let request = BGAppRefreshTaskRequest(identifier: backgroundTaskIdentifier) request.earliestBeginDate = Date(timeIntervalSinceNow: 24*60*60) do { try BGTaskScheduler.shared.submit(request) print("[AppDelegate] Daily background task scheduled.") } catch { print("[AppDelegate] Could not schedule daily background task: \(error.localizedDescription)") } } // Handle the background task when it's triggered by the system func handleHealthDataUpload(task: BGAppRefreshTask) { print("[AppDelegate] Background task triggered.") // Call your upload function with completion handler HealthStoreManager.shared.fetchAndUploadHealthData { success in if success { print("[AppDelegate] Upload completed successfully.") task.setTaskCompleted(success: true) // Schedule the next day's upload after a successful upload self.scheduleDailyUpload() } else { print("[AppDelegate] Upload failed.") task.setTaskCompleted(success: false) } } // Handle task expiration (e.g., if upload takes too long) task.expirationHandler = { print("[AppDelegate] Background task expired.") task.setTaskCompleted(success: false) } } }

HI, swiftdata is new to me and any help would be appreciated. In my swiftui app I have a functionality that reinstates the database from an archive. I first move the three database files (database.store datebase.store-wal and database.store-shm) to a new name (.tmp added for backup incase) and then copy the Archived three files to the same location. the move creates the following errors: " BUG IN CLIENT OF libsqlite3.dylib: database integrity compromised by API violation: vnode renamed while in use: /private/var/mobile/Containers/Data/Application/499A6802-02E5-4547-83C4-88389AEA50F5/Library/Application Support/database.store.tmp invalidated open fd: 4 (0x20)" I get the same message in console for all three files. then I reinitialise the model container and get no errors as my code below .... let schema = Schema([....my different models are here]) let config = ModelConfiguration("database", schema: schema) do { // Recreate the container with the same store URL let container = try ModelContainer(for: schema, configurations: config) print("ModelContainer reinitialized successfully!") } catch { print("Failed to reinitialize ModelContainer: (error)") } } I get the success message but when I leave the view (backup-restore view) to the main view I get: CoreData: error: (6922) I/O error for database at /var/mobile/Containers/Data/Application/499A6802-02E5-4547-83C4-88389AEA50F5/Library/Application Support/database.store.
