Reply to iPAD: achieve UserClient's privileges in background to have robust IOServiceAddMatchingNotification(...) as if ~[Background modes][Enable external communications].
So, first off, there are two critical details I need to clarify: Note in MAC OS everything (same DExt and UserClient-code) works fine in the background and in the foreground. macOS doesn't implement any of the app suspension semantics iPadOS does, which means you can't really compare the behavior of the two systems. That leads to here: 1 variation A) UserClientApp has attribute [Background modes][Enable external communications]. The external-accessory background mode is totally unrelated to DriverKit and isn't actually doing anything in your app. It allows apps using the ExternalAccessory framework to communicate with their accessory in the background, but that framework (iOS 3.0) and the background mode (iOS 4.0) are MUCH older than DriverKit. Making this as explicit as possible: B) A way to pursue Apple-store to accept (without MFI) an UserClientApp with [Enable external communication]. ...adding external-accessory is not changing ANYTHING about how your app wakes/sleep in the background.

Reply to Cluster not displaying in CarPlay POI template on iPhone 14 with iOS 26.0.1
Thank you for your post. I have a few questions. Is that your application, Zeon Charging? You also mentioned that the bug appears on the iPhone 14 with iOS 16.0.1 but does not occur on the iPhone 16 with the same version of iOS. Have you tested the latest beta version of iOS? The crucial aspect is that the same version of iOS is experiencing the issue, but the iPhone model is different. Is that correct? Do you get the same results with just the relevant code in a small test project? If so, please share a link to your test project. That'll help us better understand what's going on. If you're not familiar with preparing a test project, take a look at Creating a test project. Albert Pascual

Beta] iOS + Apple Watch Fitness App That Tracks Chores, Looking for Testers
I’m looking for iOS and Apple Watch users to help beta test ChoreFit, a fitness app that transforms everyday chores into measurable workouts using NEAT (Non-Exercise Activity Thermogenesis) science. What it does: • Tracks chores like vacuuming, mopping, and laundry as real workouts • Syncs with Apple Health for steps, heart rate, and calories • Lets you start or pause chores right from your Apple Watch • Adjusts effort based on body weight and optional weighted vests What I need from testers: • Install via TestFlight (link provided once approved) • Use the app during normal household tasks • Share feedback on usability, Apple Watch sync, and calorie accuracy If you’re interested in movement tracking, fitness analytics, or wearable integration, I’d love your help validating and refining this app before public release.

Could not located developer disk image for this device
I just downloaded xCode 26.0.1 and installed it overtop of my previous version of xCode (I don't know the version, but it was less than a year old). Everything was working fine with the previous version of xCode, but with v 26.0.1, I am getting the following popup error message when trying to install my app to some of my tethered devices: Could not located developer disk image for this device This occurs with an iPhone 7 with iOS 14.8 and an iPad Pro (1st gen) with iOS 13.5.1. Again, these devices had no problem launching an app from xCode while tethered prior to the v 26.0.1 install. I do have the following folders in the UsersMyNameLibraryDeveloperxCodeiOS DeviceSupport folder: 12.4.1 (16G102) 12.4.1 (16...2) arm64e 13.5.1 (17F80) 14.4.2 (18D70) 14.6 (18F72) 14.7.1 (18G82) 14.8 (18H17) 15.0.2 (19A404) 15.1 (19B74) arm64e 15.3.1 (19D52) 15.3.1 (19...2) arm64e 16.1 (20B82) arm64e 16.3.1 (20...7) arm64e

Reply to Ghost Padding on NavigationBarPlatterContainer
Here's an sample code that can produce the problem. It happens on rotate in simulator, only in iOS 26.* Expectation: should have the same lead spacing regardless of the rotation of the device. struct ContentView: View { @State private var showingSharePopover = false var body: some View { NavigationStack { VStack { Button { showingSharePopover = true } label: { Label(Show Share Options, systemImage: square.and.arrow.up) .font(.title2) .padding(.vertical, 10) .padding(.horizontal, 20) } .buttonStyle(.borderedProminent) .tint(.indigo) .controlSize(.large) .shadow(radius: 5) .sheet(isPresented: $showingSharePopover, content: { }) } .navigationBarBackButtonHidden(false) .toolbar { ToolbarItem(placement: .topBarLeading) { Button { } label: { HStack { Image(systemName: square.and.arrow.left) Text(Done) } } } } .padding() } } }

Reply to Unable to receive HealthKit updates when app is force-quit — need clarification on background delivery limits
As explained in iOS Background Execution Limits ==> When the user ‘force quits’ an app by swiping up in the multitasking UI, iOS interprets that to mean that the user doesn’t want the app running at all. So: If the app is running, iOS terminates it. iOS also sets a flag that prevents the app from being launched in the background. That flag gets cleared when the user next launches the app manually. This gesture is a clear statement of user intent; there’s no documented way for your app to override the user’s choice. So, the best approach to this is first train your users so they understand that force quit will stop data collection. And if they still do it, then it is their choice for you to respect. So, how you solve this depends on your use case and the user experience you are trying to achieve. You can send push notifications if your server suspects that this has happened (no data updated for a while, for example) to encourage the users to tap on it, which will relaunch

iOS 17.x Simulator (Xcode 15.4): OpenGL/EAGL app shows black screen or exits; clean SDL2 rebuild + flags fix it on 17.2 (17.5 still affected)
Context Host: macOS 14.7.6 on Apple Silicon (Mac mini M2) Xcode 15.4 Simulator runtimes installed: iOS 17.2, 17.4, 17.5 Tech stack: Kivy/kivy-ios, SDL2 (OpenGL ES/EAGL), Python 3.11 App type: minimal Kivy “Hello World” (no special entitlements, no camera/mic) Observed On iOS 17.5 Simulator the app often shows a black screen or exits immediately (no crash dialog). On iOS 17.2 Simulator the same build runs fine (after a clean rebuild of SDL2 and proper xcodebuild flags). What fixed it for 17.2 Clean rebuild of SDL2 (no cached artifacts), then build python/kivy/app. xcodebuild WITHOUT OTHER_CFLAGS=-Umain -DSDL_MAIN_HANDLED. Typical flags: ONLY_ACTIVE_ARCH=YES, EXCLUDED_ARCHS=i386 x86_64, IPHONEOS_DEPLOYMENT_TARGET=16.0. Optionally enforcing EAGL RGBA8 + retained backing + opaque helped when testing, but the clean SDL2 rebuild already resolved black screen on 17.2. Still problematic 17.5 Simulator still exhibits black screen/early exit for this OpenGL ES path (no clear console/

Missing Top Separator in .plain UITableView Sections on iOS 26
Hi Apple Team and community, We've noticed a change in how UITableView separators are rendered in iOS 26 (tested using Xcode 26.0), and we'd like to confirm if this is an intentional behaviour change or a potential bug. Issue Description In a .plain-style UITableView, the top separator line above the first cell in each section is no longer rendered in iOS 26. We've confirmed that this separator is also absent from the view hierarchy. This issue did not occur in previous iOS versions (e.g., iOS 18), where the top separator above the first cell of a section was rendered as expected. The issue doesn't occur for UITableView with no sections. Expected Behavior When using a .plain style UITableView, the standard top separator should appear above the first cell of each section, as part of the default system rendering. Actual Behavior In iOS 26, this top separator is missing, even though the rest of the separators render normally. Environment iOS version: iOS
