Overview

In my app I want to integrate a personilized Lock Screen. Does anybody know how that works?

I want develop an app for real-time streaming spatial video transmission from an Apple Vision Pro to another Apple Vision Pro and play, like MV-HEVC, does it's possible? If it's possible how to make it?

I am profiling a simple SwiftUI test app on my new iPhone through my new MacBook Pro and everything is version 26.2 (iOS, macOS, Xcode). I run Instruments with the SwiftUI template using all of the default settings and get absolutely zero data after interacting with the app for about 20 seconds. Using the Time Profiler template yields trace data. Trying the SwiftUI template again with the sample Landmarks app has the same issue as my app.

Hi, How to enable multitouch on ARView? Touch functions (touchesBegan, touchesMoved, ...) seem to only handle one touch at a time. In order to handle multiple touches at a time with ARView, I have to either: Use SwiftUI .simultaneousGesture on top of an ARView representable Position a UIView on top of ARView to capture touches and do hit testing by passing a reference to ARView Expected behavior: ARView should capture all touches via touchesBegan/Moved/Ended/Cancelled. Here is what I tried, on iOS 26.1 and macOS 26.1: ARView Multitouch The setup below is a minimal ARView presented by SwiftUI, with touch events handled inside ARView. Multitouch doesn't work with this setup. Note that multitouch wouldn't work either if the ARView is presented with a UIViewController instead of SwiftUI. import RealityKit import SwiftUI struct ARViewMultiTouchView: View { var body: some View { ZStack { ARViewMultiTouchRepresentable() .ignoresSafeArea() } } } #Preview { ARViewMultiTouchView() } // MARK: Representable ARView struct ARViewMultiTouchRepresentable: UIViewRepresentable { func makeUIView(context: Context) -> ARView { let arView = ARViewMultiTouch(frame: .zero) let anchor = AnchorEntity() arView.scene.addAnchor(anchor) let boxWidth: Float = 0.4 let boxMaterial = SimpleMaterial(color: .red, isMetallic: false) let box = ModelEntity(mesh: .generateBox(size: boxWidth), materials: [boxMaterial]) box.name = "Box" box.components.set(CollisionComponent(shapes: [.generateBox(width: boxWidth, height: boxWidth, depth: boxWidth)])) anchor.addChild(box) return arView } func updateUIView(_ uiView: ARView, context: Context) { } } // MARK: ARView class ARViewMultiTouch: ARView { required init(frame: CGRect) { super.init(frame: frame) /// Enable multi-touch isMultipleTouchEnabled = true cameraMode = .nonAR automaticallyConfigureSession = false environment.background = .color(.gray) /// Disable gesture recognizers to not conflict with touch events /// But it doesn't fix the issue gestureRecognizers?.forEach { $0.isEnabled = false } } required dynamic init?(coder decoder: NSCoder) { fatalError("init(coder:) has not been implemented") } override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) { for touch in touches { /// # Problem /// This should print for every new touch, up to 5 simultaneously on an iPhone (multi-touch) /// But it only fires for one touch at a time (single-touch) print("Touch began at: \(touch.location(in: self))") } } } Multitouch with an Overlay This setup works, but it doesn't seem right. There must be a solution to make ARView handle multi touch directly, right? import SwiftUI import RealityKit struct MultiTouchOverlayView: View { var body: some View { ZStack { MultiTouchOverlayRepresentable() .ignoresSafeArea() Text("Multi touch with overlay view") .font(.system(size: 24, weight: .medium)) .foregroundStyle(.white) .offset(CGSize(width: 0, height: -150)) } } } #Preview { MultiTouchOverlayView() } // MARK: Representable Container struct MultiTouchOverlayRepresentable: UIViewRepresentable { func makeUIView(context: Context) -> UIView { /// The view that SwiftUI will present let container = UIView() /// ARView let arView = ARView(frame: container.bounds) arView.autoresizingMask = [.flexibleWidth, .flexibleHeight] arView.cameraMode = .nonAR arView.automaticallyConfigureSession = false arView.environment.background = .color(.gray) let anchor = AnchorEntity() arView.scene.addAnchor(anchor) let boxWidth: Float = 0.4 let boxMaterial = SimpleMaterial(color: .red, isMetallic: false) let box = ModelEntity(mesh: .generateBox(size: boxWidth), materials: [boxMaterial]) box.name = "Box" box.components.set(CollisionComponent(shapes: [.generateBox(width: boxWidth, height: boxWidth, depth: boxWidth)])) anchor.addChild(box) /// The view that will capture touches let touchOverlay = TouchOverlayView(frame: container.bounds) touchOverlay.autoresizingMask = [.flexibleWidth, .flexibleHeight] touchOverlay.backgroundColor = .clear /// Pass an arView reference to the overlay for hit testing touchOverlay.arView = arView /// Add views to the container. /// ARView goes in first, at the bottom. container.addSubview(arView) /// TouchOverlay goes in last, on top. container.addSubview(touchOverlay) return container } func updateUIView(_ uiView: UIView, context: Context) { } } // MARK: Touch Overlay View /// A UIView to handle multi-touch on top of ARView class TouchOverlayView: UIView { weak var arView: ARView? override init(frame: CGRect) { super.init(frame: frame) isMultipleTouchEnabled = true isUserInteractionEnabled = true } required init?(coder: NSCoder) { fatalError("init(coder:) has not been implemented") } override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) { let totalTouches = event?.allTouches?.count ?? touches.count print("--- Touches Began --- (New: \(touches.count), Total: \(totalTouches))") for touch in touches { let location = touch.location(in: self) /// Hit testing. /// ARView and Touch View must be of the same size if let arView = arView { let entity = arView.entity(at: location) if let entity = entity { print("Touched entity: \(entity.name)") } else { print("Touched: none") } } } } override func touchesCancelled(_ touches: Set<UITouch>, with event: UIEvent?) { let totalTouches = event?.allTouches?.count ?? touches.count print("--- Touches Cancelled --- (Cancelled: \(touches.count), Total: \(totalTouches))") } }

Hi I'm developing an app that autofills Passkeys. The app allows the user to authenticate to their IdP to obtain an access token. Using the token the app fetches from <server>/attestation/options. The app will generate a Passkey credential using a home-grown module - the extension has no involvement, neither does ASAuthorizationSecurityKeyPublicKeyCredentialProvider. I can confirm the passkey does get created. Next the credential is posted to <server>/attestation/results with the response JSON being parsed and used to create a ASPasskeyCredentialIdentity - a sample of the response JSON is attached. Here is my save function: static func save(authenticator: AuthenticatorInfo) async throws { guard let credentialID = Data(base64URLEncoded: authenticator.attributes.credentialId) else { throw AuthenticatorError.invalidEncoding("Credential ID is not a valid Base64URL string.") } guard let userHandle = authenticator.userId.data(using: .utf8) else { throw AuthenticatorError.invalidEncoding("User handle is not a valid UTF-8 string.") } let identity = ASPasskeyCredentialIdentity( relyingPartyIdentifier: authenticator.attributes.rpId, userName: authenticator.userId, // This is what the user sees in the UI credentialID: credentialID, userHandle: userHandle, recordIdentifier: authenticator.id ) try await ASCredentialIdentityStore.shared.saveCredentialIdentities([identity]) } Although no error occurs, I don't get any identities returned when I call this method: let identities = await ASCredentialIdentityStore.shared.credentialIdentities( forService: nil, credentialIdentityTypes: [.passkey] ) Here is the Info.plist in the Extension: <plist version="1.0"> <dict> <key>NSExtension</key> <dict> <key>NSExtensionAttributes</key> <dict> <key>ASCredentialProviderExtensionCapabilities</key> <dict> <key>ProvidesPasskeys</key> <true/> </dict> <key>ASCredentialProviderExtensionShowsConfigurationUI</key> <true/> </dict> <key>NSExtensionPointIdentifier</key> <string>com.apple.authentication-services-credential-provider-ui</string> <key>NSExtensionPrincipalClass</key> <string>$(PRODUCT_MODULE_NAME).CredentialProviderViewController</string> </dict> </dict> </plist> The entitlements are valid and the app and extension both support the same group. I'm stumped as to why the identity is not getting saved. Any ideas and not getting retrieved. attestationResult.json

Hi everyone, I am building an SMS filtering app using the IdentityLookup framework. My main application handles the user login and receives a JWT. I need my ILMessageFilterExtension to use this JWT to authenticate its backend requests via context.deferQueryRequestToNetwork. Since the extension is sandboxed and doesn't share a URLSession or standard Keychain with the main app, I am trying to use the Shared Web Credentials mechanism as suggested in the documentation. My Questions: Is SecAddSharedWebCredential still the recommended way to "bridge" a token from the main app to the messagefilter service in 2026? If the backend returns a 401 Unauthorized with a WWW-Authenticate: Basic realm="api.mydomain.com" header, will iOS automatically retry the request with the stored token? Are there any specific AASA (Apple App Site Association) requirements for the messagefilter key? Does it need to be a separate top-level object or nested? Current Setup: Entitlements: Both Main App and Extension have messagefilter:api.mydomain.com and webcredentials:api.mydomain.com. Main App Code: Swift SecAddSharedWebCredential("api.mydomain.com" as CFString, "UserAccount" as CFString, "my_jwt_token" as CFString) { error in // Returns nil (success) } AASA File: JSON { "messagefilter": { "apps": ["TEAMID.bundle.id"] } } Despite this, I see the first 401 in my server logs, but the automatic retry with the Authorization header never happens. Has anyone successfully implemented this "silent" handshake recently?

I have an MAUI based application build and ready for the distribution. The application is working perfectly in the debug environment on the simulator. So the app logic is working correctly as expected without any errors. But when a release build is created the application crashes on the simulator and physical device. I'm developing the application using .Net 10 framework with target device iOS 26. The Supported OS Platform is set to 15.0 in csproj file. Also have the entitlements. plist file set in the csproj. The IDe used is Visual Studio Code for Mac (MAC OS). The application uses MSAL for the login / authentication purpose (Microsoft.Identity.Client) and SQLite Database (Sqlite-net-pcl) Message: Kindly guide me to build the application correctly in release version and get the ipa file ready for the in house distribution that could be deployed correctly on the physical device with iOS 18 / 26.

I previously had an account that changed devices when purchasing the Apple Developer Program, which prevented me from continuing the purchase. Customer service stated that they did not have the authority to handle it. So I registered a new ID, but I still couldn't register. Now, both accounts are unable to purchase the Apple Developer Program because the button is grayed out. I consulted customer service, and one of the representatives informed me that my identity is no longer eligible for purchasing the Apple Developer Program. I don't want to purchase using someone else's identity. Is there a way to resolve this? I feel like the purchasing process is locked.

I work on an app that saves data to the Documents folder in the users iCloud Drive. This uses the iCloud -> iCloud Documents capability with a standard container. We've noticed an issue where a user will delete the apps data by doing to Settings > {Name} > iCloud > Storage > App Name > select "delete data from iCloud", and then our app can no longer write to or create the Documents folder. Once that happens, we get this error: Error Domain=NSCocoaErrorDomain Code=513 "You don't have permission to save the file "Documents" in the folder "iCloud~your~bundle~identifier"." UserInfo={NSFilePath=/private/var/mobile/Library/Mobile Documents/iCloud~your~bundle~identifier/Documents, NSURL=file:///private/var/mobile/Library/Mobile%20Documents/iCloud~your~bundle~identifier/Documents, NSUnderlyingError=0x1102c7ea0 {Error Domain=NSPOSIXErrorDomain Code=13 "Permission denied"}} This is reproducible using the sample project here https://developer.apple.com/documentation/uikit/synchronizing-documents-in-the-icloud-environment. Steps to reproduce in that project: Tap the plus sign in the top right corner to create a new document Add a document name and tap "Save to Documents" Go to Settings > {Name} > iCloud > Storage > SimpleiCloudDocument App Name > select "delete data from iCloud" Reopen the app and repeat steps 1-2 Observe error on MainViewController+Document.swift:59 Deleting and reinstalling the app doesn't seem to help.

I’m a developer working on a Safari Web Extension that’s distributed via the App Store and also tested locally through Xcode. I’m running into an issue that’s affecting my ability to debug errors reported to my Sentry error logging instance from production. The Problem When an error is thrown in one of my extension scripts (e.g., background.js, popup.js, or content.js), the error is sent to Sentry but the captured JavaScript error stack trace replaces the file paths with the webkit-masked-url://hidden placeholder like this: ReferenceError: Cannot access uninitialized variable. at ? (webkit-masked-url://hidden/:14677:28) at ? (webkit-masked-url://hidden/:16307:3) This happens consistently across both App Store builds and local Xcode runs. It prevents me from seeing which script the error came from or resolving the actual source code lines using uploaded source maps in Sentry. My Setup Safari Version: 18.5 (Stable on macOS) Distribution: App Store and local Xcode development Extension Type: Safari Web Extension Error Reporting: Sentry (@sentry/browser SDK) Bundler: Webpack with inline-source-map What I’ve Confirmed I can see the actual source files in Safari’s Web Inspector under the Sources tab when the extension is running. My source maps are uploaded to Sentry correctly and are associated with the matching release. Errors from Safari are being captured by Sentry, but the file URLs are masked, so stack traces cannot be resolved against my original source. My Question Is this behavior (masking file URLs in stack traces with webkit-masked-url://hidden/) intentional for Safari Web Extensions? If so, is there any supported method or workaround to allow exception stack traces to reveal the original script path (e.g., popup.js, background.js) so tools like Sentry or even console logs can point to real locations? I fully understand the privacy/security rationale behind the masking, but as the extension developer, this is making it extremely difficult to debug runtime issues in production. I’d really appreciate any insight into: Whether this masking is expected and permanent behavior If there are any entitlements, debug settings, or Info.plist keys that can alter this behavior for development or for trusted/own extensions If Apple recommends a different way to log extension errors that includes script name or source references Thanks in advance for your help! I’m happy to share more technical details or try out suggestions.

I am adding NSFileProviderPartialContentFetching support to an existing NSFileProviderReplicatedExtension. My backend has a high "Time To First Byte" latency (approx. 3 seconds) but reasonable throughput once the connection is established. I am observing a critical behavior difference between Partial Content Fetching and standard Materialization that causes sequential reads (e.g., dd, Finder copies, Adobe apps) to fail with timeouts. The Scenario: I have a 2.8 GB file. I attempt to read it sequentially using dd. **Baseline (Working): Partial Fetching Disabled ** I do not conform to NSFileProviderPartialContentFetching. The system triggers fetchContents(for:version:request:completionHandler:). My extension takes 3 seconds to connect, then streams the entire 2.8 GB file. Result: Success. The OS waits patiently for the entire download (minutes) without timing out, then dd reads the file instantly from the local disk. **The Issue: Partial Fetching Enabled ** I add conformance to NSFileProviderPartialContentFetching. The system requests small, aligned chunks (e.g., 16KB or 128KB). My extension fetches the requested range. This takes ~3 seconds due to network latency. The first few chunks succeed, but shortly after, the operation fails with Operation timed out. It appears the VFS kernel watchdog treats these repeated 3-second delays during read() syscalls as a stalled drive and kills the operation. **My Questions: ** Is there a documented timeout limit for fetchPartialContents completion handlers? It seems strictly enforced (similar to a local disk I/O timeout) compared to the lenient timeout for full materialization. Is NSFileProviderPartialContentFetching inherently unsuitable for high-latency backends (e.g., cold storage, slow handshakes), or is there a mechanism to signal "progress" to the kernel to reset the I/O watchdog during a slow partial fetch? Does the system treat partial fetching as "Online/Direct I/O" (blocking the user application) whereas full fetch is treated as "Offline/Syncing" (pausing the application), explaining the difference in tolerance? Any insights into the VFS lifecycle differences between these two modes would be appreciated.

On iOS Devices with ProMotion (120HZ) if you animate Elements on your Page with animation-timeline you get Ghosting Effects. You can not see the Ghosting with a Simulator or on Screenshots, only on real Devices. To Reproduce I made a Minimal Example: https://codesandbox.io/p/sandbox/120hztest-xrwgtc When you scroll quickly on the Page with an iOS 120HZ Device (https://en.wikipedia.org/wiki/List_of_smartphones_with_a_high_refresh_rate_display) you will see ghosting on the Top of the right Element (animation-timeline) and no ghosting on the other animated Element. (I edited the Screenshot, to Illustrate how the Effect looks like, since it is only visible on the real Display)

I am in no longer contact with the software contract company that has developed and deployed my mobile app to App store via their account. how do I gain ownership of the app? will the store allow me to develop and deploy the app under same name?

Hi, we've been developing an XR application for Apple Vision Pro which has worked fine so far. Now that the SDKs have updated to 26.2 (for Xcode and AVP versions) we've run into an error that prevents the app from launching. I get the following error when running the application in the AVP Simulator (building for destination Apple Vision Pro (26.2), and my colleague gets the same error when building for the device itself and launching there. BUG IN CLIENT: For mixed reality experiences please use cp_drawable_compute_projection API Type: Error | Timestamp: 2026-01-13 09:21:57.242191+02:00 | Process: My XR App | Library: CompositorNonUI | TID: 0x75e2c (copied with "all metadata") How can we debug this further? The error in the console doesn't seem to give any stack trace or clear pointer to the code which relates to it. I've tried searching for CompositorNonUI, but that doesn't yield any results in our project (nor Google nor the Apple developer forums). There is one post in the forum that has a similar error (https://developer.apple.com/forums/thread/788500?answerId=845039022#845039022) but searching in our project and it's dependencies, we don't seem to use ".tangent" anywhere either. Any help in either debugging to find more details on where the issue happens or pointers to fixing it much appreciated, thanks!

I am developing a utility application for macOS. In the next version, I would like to access data files from multiple third-party web browsers. However, requiring users to manually select and grant access to each browser’s folder individually would be inconvenient from a usability perspective. Therefore, I am considering requesting Full Disk Access for my app. Is it realistic to expect App Store review approval when requesting Full Disk Access? Under what conditions or use cases is such permission typically accepted by Apple? I would greatly appreciate any advice or experiences you can share.

Hi all, I have setup my app to use SwiftData with CloudKit sync. I have a production environment and development environment. I can reset the development environment for myself and all users in CloudKit console, but I can't reset the production one as it's tried to users' iCloud accounts, so I've added a button in-app for that feature. In the onboarding of my app, I pre-seed the DB with some default objects, which should be persisted between app install. The issue I'm running into is that I'm unable to force-pull these models from iCloud during the onboarding of a clean re-install, which leads to the models later appearing as duplicates once the user has been on the app for a few minutes and it has pulled from their iCloud account. If anyone has any suggestions on how to handle this issue, I would greatly appreciate it.

I am trying to correctly manage about 20 Mac, iPhones and PC inside a Wi-Fi network built through System Settings > Sharing > Internet Sharing To achieve this task I defined a complete configuration file: /etc/bootpd.plist which is used by /usr/libexec/InternetSharing. But every time /usr/libexec/InternetSharing is starting the file /etc/bootpd.plist is overwritten by another file and my configuration is thus fully lost. How to set a correct /etc/bootps.plist file and avoid its total overwrite by /usr/libexec/InternetSharing? Is it necessary to write this bootpd.plist in some other directory for /usr/libexec/InternetSharing to load it without destroying it? I got the same configuration total erase on macOS Big Sur and Sequoia.

The Problem The Family Activity Picker shows only the child's app categories on the guardian's/parent's device. The application names from the child's device are not showing on the guardian's/parent's device. The authorization is done on the child's device via try await AuthorizationCenter.shared.requestAuthorization(for: .child) Usage of the family activity picker on the guardian's/parent's device struct ContentView: View { @State private var isPresented = true @StateObject private var familyControlsHelper = FamilyControlsHelper.shared var onClose: () -> Void var body: some View { ZStack { Color.black.opacity(0.1).ignoresSafeArea() } .familyActivityPicker( isPresented: $isPresented, selection: $familyControlsHelper.familyActivitySelection ) .onChange(of: isPresented) { _ in if !isPresented { onClose() } } } } IMPORTANT Both devices are real (not simulators), and the app has granted distribution Family Controls entitlement. Question Is this the expected behavior? Or the child's app should appear on the guardian's device? Thanks.

I created an application extension that uses IdentityLookup framework for SMS filtering. How can I deploy my product as a library? I tried wrapping it as a framework, but it was not successful.
