Team-scoped keys introduce the ability to restrict your token authentication keys to either development or production environments. Topic-specific keys in addition to environment isolation allow you to associate each key with a specific Bundle ID streamlining key management. For detailed instructions on accessing these features, read our updated documentation on establishing a token-based connection to APNs.

Hi, I need to write an application (possibly using C) to communicate with a USB High Speed Device CDC class I am developing, but unfortunately I have no development experience under Mac OS, so I am here to ask for a few help/advice. I hope I am in the right place. Since I have a working code using libusb on Linux, I have first tried to use such lib on a Mac OS without success. The device is listed correctly using ioreg -w0 -l -p but it seems to be always busy: MYUSBDEVICE@fa410000 <class IOUSBHostDevice, id 0x100001769, registered, matched, active, busy 0 (262 ms), retain 24> in fact, attempting to use libusb always results in error: LIBUSB_ERROR_NOT_FOUND libusb_bulk_transfer: Entity not found After searching a bit, I have read that it is impossible (?) to use libusb on MacOS. Then I came across these following pages: https://developer.apple.com/library/archive/documentation/DeviceDrivers/Conceptual/USBBook/USBDeviceInterfaces/USBDevInterfaces.html https://developer.apple.com/documentation/usbdriverkit I would possible avoid to write a CDC kernel driver for my application, so link #2 seems more appropriate to what I need. But isn't it available any API to develop USB CDC communications C application on MacOS ? Any suggestion is appreciated. Thanks in advance. Regards, Simon

Hello, We have a Push-to-Talk (PTT) application that is already well established and widely used. Our app has the proper VoIP entitlement, which we are using to wake up the app and establish a WebSocket connection for real-time communication. We are also using CallKit as a supporting mechanism, but not as the primary interaction upon receiving the VoIP Push, since our use case differs from traditional full-duplex VoIP calls. While our implementation works correctly in many cases, we have noticed a consistent issue where, after multiple VoIP Push notifications, the system still delivers the push, but prevents the WebSocket from reconnecting. At this point, all connection attempts return errors such as: • "Software caused connection abort" This issue persists until the app is manually relaunched, after which the behavior resets and repeats. We are aware that VoIP Push was originally designed for full-duplex calls, but since Apple allows its use for other purposes through the entitlement, we would like to understand why this limitation is occurring and how to handle it properly. Questions: 1. Is iOS enforcing stricter background execution rules after multiple VoIP Push events within a short period? 2. Are there any recommended best practices to ensure reliable WebSocket reconnection in this scenario?

I have an accessory which uses both Bluetooth and WiFi to communicate with the app. I am trying to migrate to Accessory Setup Kit. However, the API expects both the bluetooth identifiers and WIFI SSID or SSID prefix in the ASDiscoveryDescriptor. The problem is we only have the WIFI SSID after BLE pairing. Our current flow looks like this: Pair via BLE Connect via BLE Send a BLE command to request WIFI settings (SSID and password) (Each device has a different SSID and password) Connect to WI-FI hotspot by calling NEHotspotConfigurationManager applyConfiguration with the retrieved credentials. Is there a way to set the Wi-Fi SSID of an ASAccessory object after the initial setup? To use Accessory Setup Kit we would need something like this: Call Accessory Setup Kit with bluetooth identifiers in the descriptor, finish the setup and get ASAccessory object. Connect via BLE Send a BLE command to request WIFI settings (SSID and password) Set the SSID of the ASAccessory to the retrieved value. Connect to WI-FI hotspot by calling `NEHotspotConfigurationManager joinAccessoryHotspot. Thanks!

We are experiencing problems with the USB port on iPad Pro 11 inch (M4) model number MVW13NF/A. Our custom peripheral device (based on Raspberry Pi Pico + tinyUSB stack, is configured as a network adapter class and has communication with our App over UDP protocol. Our device also acts as a DHCP server, providing the IP address for iPad. The problem can be described as a “bus stall” or "bus hold" after sleep mode. To reproduce it we just send the iPad into sleep mode using a power button, the USB bus on M4 goes to the suspended state and won’t resume anymore when we wake the iPad up. The problem has occurred since the upgrade to iOS 18.2.1 and has not been observed before on the previously installed iOS 17 on the same iPad Pro M4. Also, the problem does not happen on the iPad Pro 11 inch (3rd gen with M1) model number MHW73FD/A, with the same iOS 18.2.1 installed. The problem also does not arise, if we connect our device via USB hub to the same iPad Pro M4. We have tested different versions of tinyUSB stack (either included in RPi Pico SDK or native unpatched). The problem is independent of the library version. It occurs always if our device is connected directly to the USB port of iPad Pro (M4) with iOS 18. It also stays after upgrading to the latest iOS 18.3 (beta) In the attached logs is (reduced for clarity) debug output from tinyUSB library about events on the USB bus. These logs were captured via RTT debugging output, using Segger J-Link debugger, so logging process does not affect the timings on the USB bus. There are three logs attached, for cases 1: "iPad Pro M4 + iOS18" (i.e. problematic case), 2: "iPad Pro M1 + iOS18", and 3: "iPad Pro M4 + iOS18 + external USB hub" (they are non-problematic cases). case1_usbd_log.txt case2_usbd_log.txt case3_usbd_log.txt This was already posted as feedback with id FB16366509

I need to read data from the user. For convenience, the data will be in a property list, so it's easy to get a dictionary containing the property list data. But, since it's coming from outside, I need to validate that the data is in the required format, i.e. it has the right keys and the right sort of data for each key, e.g. <name> has a string, <keys> has an array of appropriate values. Since this is part of a long-established product, and targets 10.13, I want to do this in Objective-C if possible. I've been working mostly with Swift in recent years, so I've forgotten a lot of what I used to know about Objective-C, I'm sure. My first thought was to obtain the value for each key and check the class type with isa, but I see that's deprecated in macOS 13 with no replacement. I don't see another way to check the class. I'm sure other people have solved the same problem, but my searches have not turned up any answers.

In mainland China, CallKit is not available. Recently, I discovered LiveCommunicationKit. Can it replace CallKit? There is no relevant introduction in the documentation. Can someone help me understand how to use it? https://developer.apple.com/documentation/livecommunicationkit

Swift recently added support for Int128. However, they do need NOT seem to be supported in SwiftData. Now totally possible I'm doing something wrong too. I have the project set to macOS 15 to use a UInt128 in @Model class as attribute. I tried using a clean Xcode project with Swift Data choosen in the macOS app wizard. Everything compiles, but it fails at runtime in both my app and "Xcode default" SwiftData: SwiftData/SchemaProperty.swift:380: Fatal error: Unexpected property within Persisted Struct/Enum: Builtin.Int128 with the only modification to from stock is: @Model final class Item { var timestamp: Date var ipv6: UInt128 init(timestamp: Date) { self.timestamp = timestamp self.ipv6 = 0 } } I have tried both Int128 and UInt128. Both fails exactly the same. In fact, so exactly, when using UInt128 it still show a "Int128" in error message, despite class member being UInt128 . My underlying need is to store an IPv6 addresses with an app, so the newer UInt128 would work to persist it. Since Network Framework IPv6Address is also not compatible, it seems, with SwiftData. So not a lot of good options, other an a String. But for an IPv6 address that suffers from that same address can take a few String forms (i.e. "0000:0000:0000:0000:0000:0000:0000:0000" =="0:0:0:0:0:0:0:0" == "::") which is more annoying than having a few expand Int128 as String separator ":". Ideas welcomed. But potentially a bug in SwiftData since Int128 is both a Builtin and conforms to Codable, so from my reading it should work.

Hello. Recently, there have been many app crash issues of unknown causes. It has been reported that the app crashes as soon as it is launched, but it is difficult to resolve the issue because it cannot be reproduced. I have attached the crash log, so please review it and provide appropriate guidance. Thank you. 2025-02-28_06-02-16.3498_+0900-65dfc1f2a58da46e9ec11a5f0f93f5a56c6858de.crash

I'm trying to implement live caller id PIR server in python and I have an issue related to evaluation key config. I don't receive the POST /key request even if I try to install the extension on new device and I had this error in device system logs: error 11:21:30.663022+0200 ciphermld requestData(byKeywords:shardIds:clientConfig:) threw an error: CipherML.CipherMLError.missingSecre t Ke y I think the reason why the evaluation key is not generated is related to this error but I'm not sure. It might be also related to HE params - I tried with the same params as in swift server example with plaintext_modulus=17 and it works, but for plaintext_modulus=65537 on the same device the system doesn't send me the evaluation key. Is there a limitation that restricts the evaluation key generation for some HE params? There is how the entire config object that I retrieve looks like: { "configs": { "Live-C aller-ID-Lookup.

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.

Hello, When attempting to assign the UNNotificationResponse to a Published property on the main thread inside UNUserNotificationCenterDelegate's method func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse) async both Task { @MainActor in } and await MainActor.run are throwing a NSInternalInconsistencyException: 'Call must be made on main thread'. I thought both of them were essentially doing the same thing, i.e. call their closure on the main thread. So why is this exception thrown? Is my understanding of the MainActor still incorrect, or is this a bug? Thank you Note: Task { await MainActor.run { ... } } and DispatchQueue.main.async don't throw any exception.

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) } } }

Here's a simple program that spoofs an ARP reply for a given IP address. If I spin up two terminal sessions on the same machine. Run this code in one window % ./spoof en0 192.168.1.7 Listening on en0 for ARP requests to 192.168.1.7 Spoofing MAC: 00:0c:87:47:50:27 And in the second window cause the OS to issue an ARP_REQ % ping 192.168.1.7 You will see the program respond to the ARP request. (Wireshark will see the ARP_REQ and ARP_REPLY packets) however my arp table isn't updated with the MAC for the IP address. There is no firewall active. % arp -a|grep 192.168.1.7 (192.168.1.7) at (incomplete) on en0 ifscope [ethernet] This is running on a MacBook pro M3 (OSX 15.4).

Hi, I want to develop an enterprise VPN app with a custom protocol. I'm following the documentation but I have no clue how to start, is there any guide I can follow?

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"

Is there any way i can show popover tip on tabItem inside of TabView TabView(selection: selected) { Group{ HomeView() .tabItem { Label { Text("Home") } icon: { Image(selected==1 ? "home-icon" : "home-unselect") } // show tip over the Home icon } .tag(1) } }

We have an application that integrates with the sharingd driver to monitor data transfers via AirDrop. Additionally, we utilize the Endpoint Security API to track file access and application activities. Prior to the Sequoia update, our solution was effectively detecting and blocking sensitive files sent via AirDrop. However, following the update, our drivers are no longer detecting these file transfers. Could you confirm if there have been any changes to the Endpoint Security API, sharingd, or any other relevant system components that might be affecting this behavior? Any insights or documentation on recent modifications would be greatly appreciated. Thanks.
