Overview

We recently adopted our app to Liquid Glass and received a complaint from a visually impaired user that VoiceOver does not read out the number of unread items in the tab bar anymore. We checked and it seems that before iOS 26/Liquid Glass, setting a tab bar item's badgeValue property also set an appropriate text to its accessibilityValue property (something like "3 items"). But with Liquid Glass tab bars, this does not seem to be the case anymore. We fixed this by providing our own accessibility value, but we're wondering whether this change was a deliberate choice or simply a bug? If this new behavior is considered a bug, I would post a bug report.

I have this code in my Virutalization application let process = Process() process.executableURL = URL(fileURLWithPath: "/usr/sbin/diskutil") process.arguments = ["image", "create", "blank", "--fs", "none", "--format", "ASIF", "--size", "2GiB", url.path ] try process.run() process.waitUntilExit() if process.terminationStatus == 0 { print("✅ Disk image creation succeeded.") } else { print("❌ Disk image creation failed with exit code \(process.terminationStatus)") } } catch { print("Process failed to launch: \(error.localizedDescription)") return } this code was working fine until Tahoe 26.2. with the update of 26.3 the system freezes at process.waitUntilExit() The code never exits and i get beech balls. This is working fine with intel macs. i am getting the problem in apple silicon m4 mac mini. Any help would be appreciated.

Dear Apple Developer Support Team, I am writing to inquire about the process for obtaining approval for the following entitlement in my iOS/macOS app: <key>com.apple.developer.networking.networkextension</key> <array> <string>content-filter-provider</string> </array> Specifically, I would like guidance on: The steps required to submit a request for this entitlement. Any necessary documentation or justification that needs to be provided to Apple. Typical review timelines and approval criteria. Any restrictions or compliance requirements associated with this entitlement. Our app intends to implement a content filtering functionality to enhance network security and user safety. We want to ensure full compliance with Apple’s policies and guidelines. Could you please provide detailed instructions or point us to the relevant resources to initiate this approval process? Thank you for your assistance.

I'm building an app that uses the Family Controls / Screen Time APIs (FamilyControls, ManagedSettings). My app has three targets, each with a distinct Bundle ID: Main App Shield Configuration Extension ShieldAction Extension All three have com.apple.developer.family-controls in their entitlements files, and they share an App Group. My question is about the distribution entitlement request form at developer.apple.com/contact/request/family-controls-distribution: does the form need to be submitted once per Bundle ID, or is a single submission for the main app sufficient to then enable Family Controls (Distribution) for the extension Bundle IDs in the developer portal as well? I've seen conflicting reports in other forum threads — some developers say one submission covers all targets, others say separate submissions are needed per Bundle ID. I've already submitted the main app, but now I am wondering whether I should submit one for each Shield extension. Thanks!

Code signing uses various different identifier types, and I’ve seen a lot of folks confused as to which is which. This post is my attempt to clear up that confusion. If you have questions or comments, put them in a new thread, using the same topic area and tags as this post. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = "eskimo" + "1" + "@" + "apple.com" Code Signing Identifiers Explained An identifier is a short string that uniquely identifies a resource. Apple’s code-signing infrastructure uses identifiers for various different resource types. These identifiers typically use one of a small selection of formats, so it’s not always clear what type of identifier you’re looking at. This post lists the common identifiers used by code signing, shows the expected format, and gives references to further reading. Unless otherwise noted, any information about iOS applies to iOS, iPadOS, tvOS, visionOS, and watchOS. Formats The code-signing identifiers discussed here a number of different formats: 10-character This is composed of 10 ASCII characters. For example, Team IDs use this format, as illustrated by the Team ID of one of Apple’s test teams: Z7P62XVNWC. Reverse-DNS This is composed of labels separated by a dot. For example, bundle IDs use this format, as illustrated by the bundle ID of the test app associated with this post: com.example.tn3NNNapp. UUID This is a standard universally unique identifier. For example, the App Store Connect API key associated with this post has a issuer UUID of c055ca8c-e5a8-4836-b61d-aa5794eeb3f4. Email or phone See the Apple Account section below for more on this. Decimal number This is a simple decimal number. For example, the Apple ID for Apple Configurator is 1037126344. The Domain Name System has strict rules about domain names, in terms of overall length, label length, text encoding, and case sensitivity. The reverse-DNS identifiers used by code signing may or may not have similar limits. When in doubt, consult the documentation for the specific identifier type. Reverse-DNS names are just a convenient way to format a string. You don’t have to control the corresponding DNS name. You can, for example, use com.<SomeCompany>.my-app as your bundle ID regardless of whether you control the <SomeCompany>.com domain name. To securely associate your app with a domain, use associated domains. For more on that, see Supporting associated domains. IMPORTANT Don’t use com.apple. in your reverse-DNS identifiers. That can yield unexpected results. Identifiers The following table summarises the identifiers covered below: Name | Format | Example | Notes ---- | ------ | ------- | ----- Team ID | 10-character | `Z7P62XVNWC` | Identifies a developer team User ID | 10-character | `UT376R4K29` | Identifies a developer Team Member ID | 10-character | `EW7W773AA7` | Identifies a developer in a team Bundle ID | reverse-DNS | `com.example.tn3NNNapp` | Identifies an app App ID prefix | 10-character | `Z7P62XVNWC` | Part of an App ID | | `VYRRC68ZE6` | App ID | mixed | `Z7P62XVNWC.com.example.tn3NNNNapp` | Connects an app and its provisioning profile | | `VYRRC68ZE6.com.example.tn3NNNNappB` | Code-signing identifier | reverse-DNS | `com.example.tn3NNNapp` | Identifies code to macOS | | `tn3NNNtool` | App group ID | reverse DNS | `group.tn3NNNapp.shared` | Identifies an app group | reverse DNS | `Z7P62XVNWC.tn3NNNapp.shared` | Identifies an macOS-style app group Managed capability request ID | 10-character | `M79GVA97FK` | Identifies a request for a managed capability App Store Connect API key ID | 10-character | `T9GPZ92M7K` | Identifies a key used for App Store Connect API authentication App Store Connect API issuer | UUID | `c055ca8c-e5a8-4836-b61d-aa5794eeb3f4` | Identifies a key issuer in the App Store Connect API Apple Account | email or phone | `user@example.com` | Identifies a user to the Developer website and App Store Connect Apple ID | decimal number | 1037126344 | Identifies an app in App Store Connect As you can see, there’s no clear way to distinguish a Team ID, User ID, Team Member ID, and an App ID prefix. You have to determine that based on the context. In contrast, you choose your own bundle ID and app group ID values, so choose values that make it easier to keep things straight. Team ID When you set up a team on the Developer website, it generates a unique Team ID for that team. This uses the 10-character format. For example, Z7P62XVNWC is the Team ID for an Apple test team. When the Developer website issues a certificate to a team, or a user within a team, it sets the Subject Name > Organisational Unit field to the Team ID. When the Developer website issues a certificate to a team, as opposed to a user in that team, it embeds the Team ID in the Subject > Common Name field. For example, a Developer ID Application certificate for the Team ID Z7P62XVNWC has the name Developer ID Application: <TeamName> (Z7P62XVNWC). User ID When you first sign in to the Developer website, it generates a unique User ID for your Apple Account. This User ID uses the 10-character format. For example, UT376R4K29 is the User ID for an Apple test user. When the Developer website issues a certificate to a user, it sets the Subject Name > User ID field to that user’s User ID. It uses the same value for that user in all teams. Team Member ID When you join a team on the Developer website, it generates a unique Team Member ID to track your association with that team. This uses the 10-character format. For example, EW7W773AA7 is the Team Member ID for User ID UT376R4K29 in Team ID Z7P62XVNWC. When the Developer website issues a certificate to a user on a team, it embeds the Team Member ID in the Subject > Common Name field. For example, an Apple Development certificate for User ID UT376R4K29 on Team ID Z7P62XVNWC has the name Apple Development: <UserName> (EW7W773AA7). IMPORTANT This naming system is a common source of confusion. Developers see this ID and wonder why it doesn’t match their Team ID. The advantage of this naming scheme is that each certificate gets a unique name even if the team has multiple members with the same name. The John Smiths of this world appreciate this very much. Bundle ID A bundle ID is a reverse-DNS identifier that identifies a single app throughout Apple’s ecosystem. For example, the test app associated with this post has a bundle ID of com.example.tn3NNNapp. If two apps have the same bundle ID, they are considered to be the same app. Bundle IDs have strict limits on their format. For the details, see CFBundleIdentifier. If your macOS code consumes bundle IDs — for example, you’re creating a security product that checks the identity of code — be warned that not all bundle IDs conform to the documented format. And non-bundled code, like a command-line tool or dynamic library, typically doesn’t have a bundle ID. Moreover, malicious code might use arbitrary bytes as the bundle ID, bytes that don’t parse as either ASCII or UTF-8. WARNING On macOS, don’t assume that a bundle ID follows the documented format, is UTF-8, or is even text at all. Do not assume that a bundle ID that starts with com.apple. represents Apple code. A better way to identify code on macOS is with its designated requirement, as explained in TN3127 Inside Code Signing: Requirements. On iOS this isn’t a problem because the Developer website checks the bundle ID format when you register your App ID. App ID prefix An App ID prefix forms part of an App ID (see below). It’s a 10-character identifier that’s either: The Team ID of the app’s team A unique App ID prefix Note Historically a unique App ID prefix was called a Bundle Seed ID. A unique App ID prefix is a 10-character identifier generated by Apple and allocated to your team, different from your Team ID. For example, Team ID Z7P62XVNWC has been allocated the unique App ID prefix of VYRRC68ZE6. Unique App ID prefixes are effectively deprecated: You can’t create a new App ID prefix. So, unless your team is very old, you don’t have to worry about unique App ID prefixes at all. If a unique App ID prefix is available to your team, it’s possible to create a new App ID with that prefix. But doing so prevents that app from sharing state with other apps from your team. Unique app ID prefixes are not supported on macOS. If your app uses a unique App ID prefix, you can request that it be migrated to use your Team ID by contacting Apple > Developer > Contact Us. If you app has embedded app extensions that also use your unique App ID prefix, include all those App IDs in your migration request. WARNING Before migrating from a unique App ID prefix, read App ID Prefix Change and Keychain Access. App ID An App ID ties your app to its provisioning profile. Specifically: You allocate an App ID on the Developer website. You sign your app with an entitlement that claims your App ID. When you launch the app, the system looks for a profile that authorises that claim. App IDs are critical on iOS. On macOS, App IDs are only necessary when your app claims a restricted entitlement. See TN3125 Inside Code Signing: Provisioning Profiles for more about this. App IDs have the format <Prefix>.<BundleOrWildcard>, where: <Prefix> is the App ID prefix, discussed above. <BundleOrWildcard> is either a bundle ID, for an explicit App ID, or a wildcard, for a wildcard App ID. The wildcard follows bundle ID conventions except that it must end with a star (*). For example: Z7P62XVNWC.com.example.tn3NNNNapp is an explicit App ID for Team ID Z7P62XVNWC. Z7P62XVNWC.com.example.* is a wildcard App ID for Team ID Z7P62XVNWC. VYRRC68ZE6.com.example.tn3NNNNappB is an explicit App ID with the unique App ID prefix of VYRRC68ZE6. Provisioning profiles created for an explicit App ID authorise the claim of just that App ID. Provisioning profiles created for a wildcard App ID authorise the claim of any App IDs whose bundle ID matches the wildcard, where the star (*) matches zero or more arbitrary characters. Wildcard App IDs are helpful for quick tests. Most production apps claim an explicit App ID, because various features rely on that. For example, in-app purchase requires an explicit App ID. Code-signing identifier A code-signing identifier is a string chosen by the code’s signer to uniquely identify their code. IMPORTANT Don’t confuse this with a code-signing identity, which is a digital identity used for code signing. For more about code-signing identities, see TN3161 Inside Code Signing: Certificates. Code-signing identifiers exist on iOS but they don’t do anything useful. On iOS, all third-party code must be bundled, and the system ensures that the code’s code-signing identifier matches its bundle ID. On macOS, code-signing identifiers play an important role in code-signing requirements. For more on that topic, see TN3127 Inside Code Signing: Requirements. When signing code, see Creating distribution-signed code for macOS for advice on how to select a code-signing identifier. If your macOS code consumes code-signing identifiers — for example, you’re creating a security product that checks the identity of code — be warned that these identifiers look like bundle IDs but they are not the same as bundle IDs. While bundled code typically uses the bundled ID as the code-signing identifier, macOS doesn’t enforce that convention. And non-bundled code, like a command-line tool or dynamic library, often uses the file name as the code-signing identifier. Moreover, malicious code might use arbitrary bytes as the code-signing identifier, bytes that don’t parse as either ASCII or UTF-8. WARNING On macOS, don’t assume that a code-signing identifier is a well-formed bundle ID, UTF-8, or even text at all. Don’t assume that a code-signing identifier that starts with com.apple. represents Apple code. A better way to identify code on macOS is with its designated requirement, as explained in TN3127 Inside Code Signing: Requirements. App Group ID An app group ID identifies an app group, that is, a mechanism to share state between multiple apps from the same team. For more about app groups, see App Groups Entitlement and App Groups: macOS vs iOS: Working Towards Harmony. App group IDs use two different forms of reverse-DNS identifiers: iOS-style This has the format group.<GroupName>, for example, group.tn3NNNapp.shared. macOS-style This has the format <TeamID>.<GroupName>, for example, Z7P62XVNWC.tn3NNNapp.shared. The first form originated on iOS but is now supported on macOS as well. The second form is only supported on macOS. iOS-style app group IDs must be registered with the Developer website. That ensures that the ID is unique and that the <GroupName> follows bundle ID rules. macOS-style app group IDs are less constrained. When choosing such a macOS-style app group ID, follow bundle ID rules for the group name. If your macOS code consumes app group IDs, be warned that not all macOS-style app group IDs follow bundle ID format. Indeed, malicious code might use arbitrary bytes as the app group ID, bytes that don’t parse as either ASCII or UTF-8. WARNING Don’t assume that a macOS-style app group ID follows bundle ID rules, is UTF-8, or is even text at all. Don’t assume that a macOS-style app group ID where the group name starts with com.apple. represents Apple in any way. Some developers use app group IDs of the form <TeamID>.group.<GroupName>. There’s nothing special about this format. It’s just a macOS-style app group ID where the first label in the group name just happens to be group Starting in Feb 2025, iOS-style app group IDs are fully supported on macOS. If you’re writing new code that uses app groups, use an iOS-style app group ID. This allows sharing between different product types, for example, between a native macOS app and an iOS app running on the Mac. Managed Capability Request ID Managed capabilities must be assigned to your account by Apple before you can use them. You apply for these using the Capability Requests tab on the Developer website. For more details, see New Capabilities Request Tab in Certificates, Identifiers & Profiles. When you make such a request, the Developer website assigns it a request ID, using the 10-character format. For example, M79GVA97FK is the request ID for an Apple test request. These request IDs are purely administrative; they have no build-time or run-time impact. App Store Connect API Keys The App Store Connect API authenticates requests using API keys. For the details, see Creating API Keys for App Store Connect API. Each API key has an associated issuer and key ID. The issuer is a UUID, for example, c055ca8c-e5a8-4836-b61d-aa5794eeb3f4. The key ID uses the 10-character format, for example, T9GPZ92M7K. These identifiers have no run-time impact, but they might be relevant when you’re building your app. For example: If your continuous integration (CI) uses the App Store Connect API, it will need an API key and its associated identifiers. If you notarise a Mac product, you might choose to authenticate using an App Store Connect API key and its associated identifiers. For an example of how to do that with notarytool, see TN3147 Migrating to the latest notarization tool. Apple Account An Apple Account is the personal account you use to access Apple services, including the Developer website and App Store Connect. Historically this was an email address, but nowadays you can also use a phone number. For more about Apple Accounts, see the Apple Account website. Your Apple Account was previously know as your Apple ID, which was confusingly similar to the next identifier. Apple ID In App Store Connect, an Apple ID refers to a decimal number that identifies your app. For example, the Apple ID for Apple Configurator is 1037126344. To see this in App Store Connect, navigate to the app record, select App Information on the left, and look for the Apple ID field. It’s a decimal number, usually around 10 digits long. You can also find this embedded in the App Store URL for the app. For example, the Apple Store URL for Apple Configurator is https://apps.apple.com/us/app/apple-configurator-2/id1037126344, which ends with its Apple ID. Note In some very obscure cases you might see this referred to as an Adam ID. Your app’s Apple ID is not used at runtime, but you may need to know it to accomplish administrative tasks. For example, most managed capability submission forms ask for your app’s Apple ID. Revision History 2026-03-05 Added the Apple Account and Apple ID sections. 2026-02-25 Added the Managed Capability Request ID and App Store Connect API Keys sections.

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

We’re having an iPad issue accessing the local network with iPadOS 26.3. We have an automation system that tests our app on an iPad using accessibility tags. the XCTest test code sends messages from the iPad via TCP/IP to setup external test equipment. The messages abruptly stopped transmitting across the iPad blood-brain barrier with iPadOS 26.3 (26.2.1 and earlier works fine). The technique that worked involved installing a helper app with the same bundleID as our app, allowing the helper app to access the network, and when our app runs it has network access through the helper. It’s clever and kludgey. Forums that we referenced in the past: https://developer.apple.com/forums/thread/663858 TN3179: Understanding local network privacy | Apple Developer Documentation I suspect that something was changed in 26.3 that closed our window. I need two things: ID what is different in 26.3 and fix the automation system. If there’s a new way for XCUITest code to access the local network I’m happy to try it out.

I'm in the process of converting my SceneKit game to RealityKit. In SceneKit I used to be able to mark nodes as selected by setting SCNMaterial.emission with a custom color. I can do the same with PhysicallyBasedMaterial.emissiveColor, but I'd like to keep my entitities unaffected by the scene lights by using UnlitMaterial. In SceneKit I can set a category mask to indicate what light should affect what node, but there doesn't seem to be such a thing in RealityKit. So at the moment it seems like I have to choose between being able to mark an entity as selected, or having entities unaffected by lighting, but not both. Is there some effect or component I can use to mark entities as selected by applying some coloring regardless of the material used?

I want to track down which part of an app contacts a given domain listed in its App Privacy Report. Following the instructions given here I am able to capture a packet trace, but traffic to the domain in question is encrypted using QUIC. Is there a way to insert e.g. mitmproxy into the capture process in order to get hold of the SSLKEYLOGFILE so that I can decrypt the traffic?

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?

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?
