macOS 15 (Sequoia): Endpoint Security client runs by hand, but LaunchDaemon fails with TCC “Full Disk Access” denial on unmanaged Macs
Platforms: macOS 15.x (Sequoia), Intel-Based App type: Endpoint Security (ES) client, notarized Developer ID app + LaunchDaemon Goal: Boot-time ES client that runs on any Mac (managed or unmanaged) Summary Our ES client launches and functions when started manually (terminal), but when loaded as a LaunchDaemon it fails to initialize the ES connection with: (libEndpointSecurity.dylib) Failed to open service: 0xe00002d8: Caller lacks TCC authorization for Full Disk Access We can’t find a supported way to grant Full Disk Access (SystemPolicyAllFiles) to a system daemon on unmanaged Macs (no MDM). Local installation of a PPPC (TCC) profile is rejected as “must originate from a user-approved MDM server.” We’re seeking confirmation: Is MDM now the only supported path for a boot-time ES daemon that requires FDA? If so, what’s Apple’s recommended approach for unmanaged Macs? Environment & Artifacts Binary (path placeholder): /Library/Application Support///App/.app/Contents/MacOS/ Universal (x86_64 + arm64

DriverKit DEXT Logs Only Once, Subsequent Logs Are Lost Despite Normal Functionality
Hello everyone, I've encountered a very strange and persistent logging issue with my DriverKit DEXT and would appreciate any insights from the community. [Problem Summary] My DriverKit DEXT, along with its companion Swift app, is functionally working perfectly. I can repeatedly call methods in the DEXT from the app (e.g., a Ping-Pong test and a StaticProcessInbandTask call) and receive the correct response every time. However, the os_log messages within my IOUserClient subclass are only successfully recorded for the very first set of interactions. After that, all subsequent logs are completely missing. What's even stranger is that all successfully recorded logs are attributed to the kernel: process, even for purely user-space methods like ExternalMethod. [Development Environment] macOS: 15.7.1 Xcode: 16.4 Hardware: MacBook Pro M1 DEXT Logging Macro (Log.h): #include #define Log(fmt, ...) do { os_log(OS_LOG_DEFAULT, [%{public}s] fmt, __FUNCTION__, ##__VA_ARGS__); } while (0) [Steps to Reproduce &

macOS App Groups / transition to profile based groups
Hi, I have a macOS app distributed through the App Store that uses an app group to share data with app extensions. The group identifier has the form: .group. In Xcode 26 I am now asked to convert the project to profile based app groups (like on iOS). My question is: Can I convert the project to profile based app groups and will the existing app group (which is prefixed with the Team ID) continue to work (and will exiting users still be able to access their data). If yes, should I add the app group with or without the Team ID prefix to the profile.

UIMenuElementAttributesKeepsMenuPresented not working when Glass Grouping changes
I'm working on a UIBarButtonItem that is supposed to be a filter button - it shows a menu in which the user can (un)check menu items. Using the UIMenuElementAttributesKeepsMenuPresented attribute on the UIActions prevents the menu to hide after the user clicks an item. The button is put alongside another button as the leftBarButtonItems of my navigation item. In iOS 26 they are grouped into a single glass container automatically. Now when the user starts filtering, I want to highlight the UIBarButton item to signal to the user that the filter is active (similar to what Apple does in the Mail app). I do that by setting the UIBarButtonItemStyle to prominent. Now that works too, but it causes the automatic glass grouping to break up and the menu to hide. I'm fine with the grouping to break up, but the menu shouldn't hide. Is this a bug or can this be prevented somehow?

Debugger Issue After Installing macOS Tahoe 26.0.1
After upgrading to macOS Tahoe 26.0.1, I encountered an issue where the debugger could no longer display standard C++ library types such as std::map, std::string, and other std:: containers. Instead, the debugger simply showed: Summary Unavailable 🧪 What I Tried • Switched from the default LLVM compiler to GDB to check if it was a debugger-related problem — no improvement. • Cleaned and rebuilt the project — the issue persisted. ✅ Solution Downgrading Xcode to version 16.4 immediately resolved the issue. According to Apple’s official Xcode support documentation, Xcode 16.4 is compatible with macOS Sequoia 15.6 and later, which includes macOS Tahoe 26.0.1. This suggests that the problem may be caused by a compatibility issue in the latest Command Line Tools bundled with newer versions of Xcode. 💡 Takeaway If you encounter the same problem: 1. Try downgrading to Xcode 16.4 or reinstalling the corresponding Command Line Tools. 2. Make sure your debugger (LLDB or GDB) is correctly linked to the appropr

In-App Purchases section missing in App Store Connect for new version submission (subscriptions)
Hi everyone, I am experiencing an issue with App Store Connect and subscriptions. My app (Couple Organizer, App ID: 6748842796) already has an approved subscription group (Premium Plans) with Monthly and Yearly Premium options. Version 1.0.0 is live in the App Store, subscriptions are working. But - When preparing version 1.1.0 for submission the “In-App Purchases and Subscriptions” section is not visible on the submission page so I am unable to attach them to the new version of the app. I tried removing the build from review and re-adding another one but the section still does not appear. Subscriptions show status approved and ready for sale . My questions: Are subscriptions automatically carried forward to new app versions once approved in the first release? Or is there a step I’m missing to explicitly attach them again in every new version? Is this the expected behavior, or is it a bug in App Store Connect UI? Screenshots available if needed. Any advice would be appreciated!

Issue with Fastlane match – "Couldn't decrypt the repo, Invalid password passed via 'MATCH_PASSWORD'"
Hi everyone, I’m running into an issue using Fastlane to upload my iOS app to TestFlight. When I run my ios beta lane, I get the following error: [18:12:27]: Couldn't decrypt the repo, please make sure you enter the right password! [18:12:27]: Invalid password passed via 'MATCH_PASSWORD' [18:12:27]: Called from Fastfile at line 7 [18:12:27]: 5: desc Build and upload to TestFlight [18:12:27]: 6: lane :beta do [18:12:27]: => 7: match( [18:12:27]: 8: type: appstore, [18:12:27]: 9: readonly: true, [18:12:27]: ``` Fastlane summary: Step Action Time (s) 1 default_platform 0 💥 match 4 The error indicates that the password provided via MATCH_PASSWORD is invalid. I’ve double-checked that the password I’m using is correct. Has anyone else run into this issue, or can anyone suggest how to properly configure MATCH_PASSWORD so Fastlane can decrypt the repo successfully? Thanks in advance!

[iOS26]UITableView drag bug
I encountered a bug with drag-and-drop sorting in ios 26. I created a UITableView for dragging and dropping to adjust the order of the list. However, when I set the height of the cells to a custom height, some cells were not displayed during the dragging process. The tools I use are the official version of Xcode16.1 and the ios 26 emulator And I can also reproduce the same problem on the real device. class ViewController: UIViewController { private let tableView: UITableView = { let tableView = UITableView.init(frame: .zero, style: .grouped) tableView.backgroundColor = .clear tableView.estimatedSectionHeaderHeight = 50 tableView.isEditing = true tableView.showsVerticalScrollIndicator = false tableView.allowsSelectionDuringEditing = true return tableView }() var content: [Int] = [] override func viewDidLoad() { super.viewDidLoad() tableView.register(FTWatchGroupPageCell.self, forCellReuseIdentifier: FTWatchGroupPageCell) tableView.delegate = self tableView.dataSource = self view.addSubview(tableView)

The bundle uses a bundle name or display name that is already taken. (90129)
The new Apple Developer account is encountering the following error: “The bundle uses a bundle name or display name that is already taken. (90129)” We used Expo to build the apps and tested several bundle identifiers and app names for the new group, following the same procedure that has worked for our other groups. However, this specific group continues to trigger the same error — “The bundle uses a bundle name or display name that is already taken. (90129)” — every time we submit a successful build through Transporter. Even after experimenting with different bundle identifiers and creating a completely new Expo project, the issue remains unresolved.

Transfer App ID from one dev account to another for existing Enterprise app
We have an enterprise app that was developed when the IT group in the U.S. had their own enterprise developer account and HQ in Europe had their own. App's were kept separate for whatever reason. Over the past few years all new app ids etc have been created in HQ account but the local US account still contains this one legacy app ID. The app it's associated with is distributed globally and on tens of thousands of devices. Is there a way to transfer the app id etc to from the local US dev account to the HQ owned global account. I know this is possible with App Store distributed app's but this is an enterprise app that is distributed to our corp owned devices through AirWatch.

[Bug] iPadOS 26: 4-Finger Fast Tap/Swipe Gesture Not Detected (Multitouch Issue)
Hi everyone I'm experiencing an issue with iPadOS 26 regarding multi-touch gesture detection. When performing a quick four-finger gesture (tap and swipe), the system often fails to recognize the input. This especially affects multi-touch gestures, such as rhythm games with difficult levels. Steps to Reproduce: Place four fingers on the screen. Perform a quick tap or a quick horizontal swipe (like the one used to switch apps). Observe whether the gesture is ignored or detected inconsistently. Expected Behavior: 4-finger multitouch gestures should be recognized regardless of gesture speed, just like previous iPadOS versions. Actual Behavior: Gestures fail to be detected when executed quickly—same gestures still work, and miss notes in rhythm games.

Reply to How to display SegmentControl in tabViewBottomAccessory inline mode like iOS 26 Photos app?
Hi @377632523@qq.com, I'm unable to reproduce the issue, as reported, in my own Xcode project. Because the provided example above will not build successfully due to missing types, I replaced your implementation with the following: import SwiftUI struct PhotosMainView: View { @State private var searchText: String = var body: some View { TabView { Tab(Library, systemImage: photo.on.rectangle) { NavigationStack { scrollView(colors: [.red, .orange, .yellow]) .navigationTitle(Library) } } Tab(Albums, systemImage: square.grid.2x2) { NavigationStack { scrollView(colors: [.yellow, .green, .teal]) .navigationTitle(Albums) } } Tab(Search, systemImage: magnifyingglass, role: .search) { NavigationStack { scrollView(colors: [.blue, .purple, .pink]) .navigationTitle(Search) .searchable(text: $searchText) } } } .tabBarMinimizeBehavior(.onScrollUp) .tabViewStyle(.sidebarAdaptable) .tabViewBottomAccessory { TimelineAccessoryView() } } // Trivial helper view to visualize scrolling. @ViewBuilder func scrollView(colors: [Color]
