Overview

A user of my app sent me a crash report. I have never seen one like this before. All of my app's symbols are replaced with three question marks (???) Thread 0 Crashed:: Dispatch queue: com.apple.main-thread 0 ??? 0x10844eb40 ??? 1 CoreFoundation 0x7ff80f155518 __CFNOTIFICATIONCENTER_IS_CALLING_OUT_TO_AN_OBSERVER__ + 137 and the binary image as 0x0 - 0xffffffffffffffff ??? (*) <00000000-0000-0000-0000-000000000000> ??? so I cannot find out where exactly the crash happened. What can cause this kind of crash report and can I do anything with it? crash.ips

I want to fade objects in and out, and while setting an entity's OpacityComponent works, animating it doesn't seem to do anything. In the following code the second sphere should fade out, but it keeps its initial opacity. On the other hand, the animation that changes its transform works. What am I doing wrong? class ViewController: NSViewController { override func loadView() { let arView = ARView(frame: NSScreen.main!.frame) let anchor = AnchorEntity(.world(transform: matrix_identity_float4x4)) arView.scene.addAnchor(anchor) let sphere = ModelEntity(mesh: .generateSphere(radius: 0.5)) anchor.addChild(sphere) sphere.components.set(OpacityComponent(opacity: 0.1)) let sphere2 = ModelEntity(mesh: .generateSphere(radius: 0.5)) sphere2.position = .init(x: 0.2, y: 0, z: 0) anchor.addChild(sphere2) sphere2.components.set(OpacityComponent(opacity: 0.1)) sphere.playAnimation(try! AnimationResource.makeActionAnimation(for: FromToByAction(to: 0, timing: .linear), duration: 1, bindTarget: .opacity)) sphere.playAnimation(try! AnimationResource.makeActionAnimation(for: FromToByAction(to: Transform(translation: SIMD3(x: 0.1, y: 0, z: 0)), timing: .linear), duration: 1, bindTarget: .transform)) view = arView } }

Hello We have a pkg installer whose signing certificate is expiring next month. It has a trusted timestamp on it. As per https://developer.apple.com/support/certificates/ it states Developer ID Installer Certificate (Mac applications) If your certificate expires, users can still install packages that were signed with this certificate as long as the package includes a trusted timestamp. Previously installed apps will continue to run. However, new installations won’t be possible until you have re-signed your installer package with a valid Developer ID Installer certificate. If your certificate is revoked, users will no longer be able to install applications that have been signed with this certificate. Wanted to check on behavior for new installations post expiration date. Since the installer has a trusted timestamp we would not need to release a new installer with new cert ?? Any guidance here would be much appreciated.

I am using Network framework for connecting two iPad devices that are connected through LAN and has Wifi enabled. I have enabled peerToPeerIncluded. I would like to understand how the framework chooses the interface types for browsing and discovering devices. When I start a browser with browser.run or listener.run, does the browser and advertiser browse and listen on all available interface types? My concern is that if it does in only one interface, Is there a chance that the browser is browsing in one interface(Lets say WiredEthernet) and the listener is listening on another interface(Lets say AWDL) and they dont discover?

Hi, I’m looking for clarification on what concurrency and consistency guarantees Apple provides when multiple targets (main app + Widget extensions) access shared storage. Specifically: 1. UserDefaults (App Group / suiteName:) • If multiple processes (app + multiple widget instances) read and write the same shared UserDefaults, what guarantees are provided? • Is access serialized internally to prevent corruption? • Are read–modify–write operations safe across processes, or can lost updates occur? 2. Core Data (shared SQLite store in App Group container) • Is it officially supported for multiple processes to open and write to the same Core Data SQLite store? • Are there recommended configurations (e.g. WAL mode) for safe multi-process access? • Is Apple’s recommendation to have a single writer process? 3. FileManager (shared container files) • If two processes write to the same file in an App Group container, what guarantees are provided by the system? • Is atomic replaceItemAt the recommended pattern for safe cross-process updates? Additionally: • Do multiple widget instances count as separate processes with respect to these guarantees? • Is there official guidance on best practices for shared persistence between app and widget extensions? I want to ensure I’m following the correct architecture and not relying on undefined behavior. Thanks.

We have a VPN app that uses NEPacketTunnelProvider with includeAllNetworks = true. We've encountered an issue where push notifications are not delivered over Wi-Fi while the tunnel is active in a pre-MFA quarantine state (tunnel is up but traffic is blocked on server side), regardless of whether excludeAPNS is set to true or false. Observed behavior Wi-Fi excludeAPNS = true - Notifications not delivered Wi-Fi excludeAPNS = false - Notifications not delivered Cellular excludeAPNS = true - Notifications delivered Cellular excludeAPNS = false - Notifications not delivered On cellular, the behavior matches our expectations: setting excludeAPNS = true allows APNS traffic to bypass the tunnel and notifications arrive; setting it to false routes APNS through the tunnel and notifications are blocked (as expected for a non-forwarding tunnel). On Wi-Fi, notifications fail to deliver in both cases. Our question Is this expected behavior when includeAllNetworks is enabled on Wi-Fi, or is this a known issue / bug with APNS delivery? Is there something else in the Wi-Fi networking path that includeAllNetworks affects beyond routing, which could prevent APNS from functioning even when the traffic is excluded from the tunnel? Sample Project Below is the minimal code that reproduces this issue. The project has two targets: a main app and a Network Extension. The tunnel provider captures all IPv4 and IPv6 traffic via default routes but does not forward packets — simulating a pre-MFA quarantine state. The main app configures the tunnel with includeAllNetworks = true and provides a UI toggle for excludeAPNS. PacketTunnelProvider.swift (Network Extension target): import NetworkExtension class PacketTunnelProvider: NEPacketTunnelProvider { override func startTunnel(options: [String : NSObject]?, completionHandler: @escaping (Error?) -> Void) { let settings = NEPacketTunnelNetworkSettings(tunnelRemoteAddress: "127.0.0.1") let ipv4 = NEIPv4Settings(addresses: ["198.51.100.1"], subnetMasks: ["255.255.255.0"]) ipv4.includedRoutes = [NEIPv4Route.default()] settings.ipv4Settings = ipv4 let ipv6 = NEIPv6Settings(addresses: ["fd00::1"], networkPrefixLengths: [64]) ipv6.includedRoutes = [NEIPv6Route.default()] settings.ipv6Settings = ipv6 let dns = NEDNSSettings(servers: ["198.51.100.1"]) settings.dnsSettings = dns settings.mtu = 1400 setTunnelNetworkSettings(settings) { error in if let error = error { completionHandler(error) return } self.readPackets() completionHandler(nil) } } private func readPackets() { packetFlow.readPackets { [weak self] packets, protocols in self?.readPackets() } } override func stopTunnel(with reason: NEProviderStopReason, completionHandler: @escaping () -> Void) { completionHandler() } override func handleAppMessage(_ messageData: Data, completionHandler: ((Data?) -> Void)?) { if let handler = completionHandler { handler(messageData) } } override func sleep(completionHandler: @escaping () -> Void) { completionHandler() } override func wake() { } } ContentView.swift (Main app target) — trimmed to essentials: import SwiftUI import NetworkExtension struct ContentView: View { @State private var excludeAPNs = false @State private var manager: NETunnelProviderManager? var body: some View { VStack { Toggle("Exclude APNs", isOn: $excludeAPNs) .onChange(of: excludeAPNs) { Task { await saveAndReload() } } Button("Connect") { Task { await toggleVPN() } } } .padding() .task { await loadManager() } } private func loadManager() async { let managers = try? await NETunnelProviderManager.loadAllFromPreferences() if let existing = managers?.first { manager = existing } else { let m = NETunnelProviderManager() let proto = NETunnelProviderProtocol() proto.providerBundleIdentifier = "<your-extension-bundle-id>" proto.serverAddress = "127.0.0.1" proto.includeAllNetworks = true proto.excludeAPNs = excludeAPNs m.protocolConfiguration = proto m.localizedDescription = "TestVPN" m.isEnabled = true try? await m.saveToPreferences() try? await m.loadFromPreferences() manager = m } if let proto = manager?.protocolConfiguration as? NETunnelProviderProtocol { excludeAPNs = proto.excludeAPNs } } private func saveAndReload() async { guard let manager else { return } if let proto = manager.protocolConfiguration as? NETunnelProviderProtocol { proto.includeAllNetworks = true proto.excludeAPNs = excludeAPNs } manager.isEnabled = true try? await manager.saveToPreferences() try? await manager.loadFromPreferences() } private func toggleVPN() async { guard let manager else { return } if manager.connection.status == .connected { manager.connection.stopVPNTunnel() } else { await saveAndReload() try? manager.connection.startVPNTunnel() } } } Steps to reproduce Build and run the sample project with above code on a physical iOS device. Connect to a Wi-Fi network. Set excludeAPNS = true using the toggle and tap Connect. Send a push notification to the device to a test app with remote notification capability (e.g., via a test push service or the push notification console). Observe that the notification is not delivered. Disconnect. Switch to cellular. Reconnect with the same settings. Send the same push notification — observe that it is delivered.

Hello, I am facing a validation error when uploading a macOS app with a Network Extension. The Error: Invalid system extension. The system extension at “[T] TEXT.app/Contents/Library/SystemExtensions/company_name.network-extension.systemextension” resides in an unexpected location. The Problem: Validation fails only when the app's Product Name contains square brackets: [T] TEXT. If I remove the brackets from the Product Name, validation passes. What I've tried: Setting Product Name to TEXT (without brackets) and CFBundleDisplayName to [T] TEXT. Cleaning Derived Data and rebuilding the archive. Verified that the extension is physically located at Contents/Library/SystemExtensions/. It seems the Apple validation tool fails to parse the bundle path correctly when it contains characters like [ or ]. Question: How can I keep the app name with brackets for the user (in System Settings and Menu Bar) while ensuring the Network Extension passes validation? Is there a way to escape these characters or a specific Info.plist configuration to satisfy the validator?"

I have gotten all necessary entitlements for all my extensions,

Hi there, Starting with iOS 26.2 RC, all my DeviceActivityMonitor.eventDidReachThreshold get activated immediately as I pick up my iPhone for the first time, two nights in a row. Feedback: FB21267341 There's always a chance something odd is happening to my device in particular (although I can't recall making any changes here and the debug logs point to the issue), but just getting this out there ASAP in case others are seeing this (or haven't tried!), and it's critical as this is the RC. DeviceActivityMonitor.eventDidReachThreshold issues also mentioned here: https://developer.apple.com/forums/thread/793747; but I believe they are different and were potentially fixed in iOS 26.1, but it points to this part of the technology having issues and maybe someone from Apple has been tweaking it.

If I see it correctly, it is currently not possible to validate a drop operation on a DynamicViewContent when using dropDestination? Just a simple example: Let's say I build a folder view on macOS where I can arrange folders freely. In this case I need to use DynamicViewContent.dropDestination to get an insertion index on drop. However, it seems that methods like dropConfiguration do not have any effect. Als dropDestionation(…, isTargeted:) seems not to be available. Here is my sample code: struct FolderRow: View { let folder: Folder var body: some View { DisclosureGroup(isExpanded: .constant(true)) { ForEach(folder.children) { child in FolderRow(folder: child) } .dropDestination(for: Folder.self) { item, idx in print("Dropped at \(idx)") } } label: { Label(folder.name, systemImage: "folder") .draggable(folder) .dropDestination(for: Folder.self) { items, _ in print("Dropped on Item") } } .dropConfiguration { session in DropConfiguration(operation: .move) } } } struct ContentView: View { @State private var folder: Folder = Folder.sampleData @State private var selection: Set<UUID> = [] var body: some View { NavigationSplitView { List(selection: $selection) { FolderRow(folder: folder) } } detail: { EmptyView() } } } The dropConfiguration is applied on the Label (in this case the "Move" cursor is used instead of the "Copy" cursor). Is there any way to do that or is it just an omission in Swift UI?

We are trying to extend our app with Push To Talk functionality by integrating the Push To Talk framework. We are extensively testing what happens if the app is running in the foreground, in the background or not running at all. When the app is in the foreground, and the user has joined a channel we maintain an open connection to our server. When a remote participant starts streaming audio, we immediately call setActiveRemoteParticipant on our PTChannelManager instance. The PTT system will than call our delegate's channelManager:didActivate audioSession method and we can successfully play the incoming audio. When the app is not running at all, there is of course no active connection initially. When another participant starts talking we send a push notification. The PTT system will start our app in the background, call the incomingPushResult method on our delegate, after returning the remote participant the PTT framework will then call the channelmanager:didJoin delegate method which we will use to re-establish the server connection, the PTT framework then calls our channelManager:didActivate audioSession delegate method and we can then successfully play audio. Now the problem. When the application was initially in the foreground and has an established server connection, we initially keep the server connection active when the app enters the background state, until a certain timeout or the system decides our app needs to be killed / removed from memory. This allows us to finish an incoming audio stream, quickly react on incoming responses etc. When we then receive an incoming audio stream after a certain delay (for example 5 seconds) we call the channelManager.setRemoteParticipant method (using try await syntax). This finishes successfully, without any error, however the channelManager:didActivate audioSession delegate method is never called. Manually setting up an audio session is not allowed either and returns an error. Our current workaround for this issue is to disconnect the server connection as soon as the app goes into the background. This will make sure our server sends a push notification, which is successful in activating the audio session after which we can play audio. However, this means we need to re-establish the connection which will introduce an unnecessary delay before we can start playback (and currently means we loose some audio). This also means we need to do extra checks when going to the background to make sure there is no active incoming stream. After each incoming stream we have to check again if we are in the background and disconnect immediately to make sure we get a push notification next time. This can of course also lead to race conditions in an active conversation where we might need to disconnect between incoming streams and if we don't do this in time we might never get an activated audio session. Now this might be by design, as Apple might not want us to keep the server connection active when the application enters the background state. But if that's the case I would expect the channelManager.setRemoteParticipant method to throw an error, but it doesn't. It returns successfully after which we would expect the audio session to get activated as well. So maybe we are not setting the capabilities of our project correctly (we might need other background permissions as well, although we already experimented with that), or we need to do something else to make this work?

Hello, I would like to discuss the behavior of the expiration of NFCPresentmentIntentAssertion (test in iOS 18.5). In the documentation we have : The intent assertion expires if any of the following occur: The intent assertion object deinitializes Your app goes into the background 15 seconds elapse BUT; in fact ; only the 1st rule is applied. The expiration seems to be random after the usage of CardSession and that's difficult to give to the user a good experience. Has someone faced the same kind of issue; or can give an explanation? Regards, François

I submitted a software update for one iOS app several days ago. It was approved two days ago. I received a message about distribution that said The status of your app has changed to Ready for Distribution I happened at the iTunes Connect website at that very moment in order to submit a totally new iOS app to the App Store. Its status said 'Removed from App Store.' I thought it was a rare mistake. Unfortunately, it's not. The one that I was submitting was approved some 15 minutes ago. I received the 'Ready for Distribution' message by email. Yet, it's been removed from the store as you see in the screenshot below. As you see in the 2nd screenshot below, it says that it's Ready for Distribution. But it's not? So is this a new norm? And we have to go back the iTunes Connect website to change the app status every time we submit a software title and then get it approved?

I am trying to migrate an app to use Network framework for p2p connection. I came across this great article for migrating to Network framework however this doesnt use the new structured concurrency. This being introduced with iOS 26, there doesnt seem to be any sample code available on how to use the new classes. I am particularly interested in code samples showing how to add TLS with PSK encryption support and handling of switching between Wifi and peer to peer interface with the new structured concurrency supported classes. Are there any good resources I can refer on this other than the WWDC video?

Hi everyone, I’m facing an issue with touch handling on newer iOS versions. I have a custom view controller implemented in Objective-C that overrides touchesEnded:. The same code works correctly on iOS 18, but on newer iOS versions (tested on iOS 26), touchesEnded: is no longer being triggered. Important observations: touchesBegan: is triggered. touchesEnded: is NOT triggered. touchesCancelled: is also NOT triggered. No code changes were made between iOS 18 and iOS 26. Same code, same sample works fine in iOS18 device but not in iOS26 device Questions: Has gesture arbitration behavior changed in recent iOS 26 versions when views are inside UIScrollView? Any clarification on whether this is intended behavior or a regression would be greatly appreciated. Thank you.

My project uses about 10 local packages. When Xcode determins its dependencies graph it includes project Foo (a package) and project Foo_Foo (???). This is a no op for normal builds, but causes the Foo package to be linked twice for test builds which then fail due to duplicate symbols. Nowhere in my repository is Foo_Foo defined or reference. Nowhere in the .xcodeproj/ folder is there mention of Foo_Foo. What am I doing wrong?

Development environment: MacBook pro Apple M1 macOS Tahoe 26.2 (25C56) Xcode 26.x iPhone 6 Plus / iOS 12.4.4 Exception description: After I upgraded to Xcode 26, my iPhone 6 Plus had a system version of 12.4.4. I was unable to perform real-device debugging, whether for existing projects or new ones. The error message from Xcode was as follows: Could not launch “xxx” Domain: IDEDebugSessionErrorDomain Code: 3 Failure Reason: Cannot launch '/private/var/containers/Bundle/Application/A44062C1-32F5-4346-B13C-FC3F39EAF7A1/xxx.app': Unspecified Even though I have already added device support for the iOS 12.4 Has Xcode 26 stopped supporting the debugging of any devices running iOS 12 system?

Description I am observing a critical issue when saving burst photos using the Photos Framework. If a burst photo with the same burstIdentifier already exists in the "Recently Deleted" album, any new assets saved via PHAssetCreationRequest are automatically merged into that deleted entry instead of appearing in the main Library or "All Photos." Environment Framework: Photos Framework (iOS) API: [[PHPhotoLibrary sharedPhotoLibrary] performChanges:...] Code Snippet The following logic is used to save the burst assets: [[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{ // 'paths' is a custom object providing the creation request PHAssetCreationRequest *assetCreationRqst = [paths assetCreationRqst]; assetCreationRqst.favorite = [FavorManager.shared isSetDownloadedAssetFavorite:self.curItem]; PHObjectPlaceholder *placeHolder = assetCreationRqst.placeholderForCreatedAsset; localIdentifier = placeHolder.localIdentifier; } completionHandler:^(BOOL success, NSError * _Nullable error) { if (success) { // The handler returns success, but the asset is invisible to the user [weakSelf handleDownloadSuccess:localIdentifier]; } // ... cleanup and completion ... }]; Steps to Reproduce Save a burst photo to the iPhone's built-in Photos app. Manually delete that burst photo so it moves to the "Recently Deleted" album. Execute the code above to save the same burst photo (or a new set containing the same burstIdentifier in its metadata). Check the main Photo Library / "All Photos" view. Observed Result The completionHandler returns success = YES, and a localIdentifier is generated. The photo does not appear in the main Library or "All Photos." The newly saved photo is silently merged into the existing burst set located inside the "Recently Deleted" folder. The user cannot see the new photo unless they manually "Restore" the deleted items from the album. Expected Behavior PHAssetCreationRequest should always result in a visible asset in the user's Library. Even if a matching burstIdentifier exists in "Recently Deleted," the system should treat the new request as a new independent asset or provide an error, rather than hiding it within a deleted collection.

Hello. Despite making my membership payment (and accidentally twice!), my membership is still not activated even after 62 hours. I contacted their support system but received no response. Does anyone have any suggestions?
