After upgrading to macOS 26, I noticed that showing a Quicklook preview in my app is very slow. Showing small text files is fine, but some other files I've tried, such as a Numbers document, take about 30 seconds (during which the indeterminate loading indicator appears) before the preview is shown. When showing the preview of an app, such as Xcode, the panel opens immediately with a placeholder image for the Xcode icon, and the actual Xcode icon is shown only after about 25 seconds. During this time many logs appear: FPItemsFromURLsWithTimeout timed out (5.000000s) for: file:///.file/id=6571367.2/ (/) FPItemsFromURLsWithTimeout timed out (5.000000s) for: file:///.file/id=6571367.23684/ (/Users) FPItemsFromURLsWithTimeout timed out (5.000000s) for: file:///.file/id=6571367.248032/ (/Users/n{9}k) FPItemsFromURLsWithTimeout timed out (5.000000s) for: file:///.file/id=6571367.248084/ (/Users/n{9}k/Downloads) Failed to add registration dmf.policy.monitor.app with error: Error Domain=NSC

Yes,I have same problem. Any one fix the problem? Here is my sample code: struct BroadcastLiveActivityGradientLayerView: View { @Environment(.colorScheme) var colorScheme private var localImageName: String { colorScheme == .light ? icon_LiveActivity_broadcast_grid_light : icon_LiveActivity_broadcast_grid_dark } private var baseBackgroundColor: Color { colorScheme == .dark ? .black : .white } var body: some View { ZStack(alignment: .topTrailing) { baseBackgroundColor let colors = LiveActivityColor.broadcastBackgroundColors(colorScheme) LinearGradient( stops: [ .init(color: colors.last ?? .clear, location: 0.0), .init(color: colors.first ?? .clear, location: 1.0) ], startPoint: UnitPoint(x: 0.81, y: 1.29), endPoint: UnitPoint(x: 1.29, y: 0.17) ) Image(localImageName) .resizable() .aspectRatio(contentMode: .fill) .frame(width: 179, height: 149) } } }

Hello there! I wanted to give a native scrolling mechanism for the Swift Charts Graph a try and experiment a bit if the scenario that we try to achieve might be possible, but it seems that the Swift Charts scrolling performance is very poor. The graph was created as follows: X-axis is created based on a date range, Y-axis is created based on an integer values between moreless 0-320 value. the graph is scrollable horizontally only (x-axis), The time range (x-axis) for the scrolling content was set to one year from now date (so the user can scroll one year into the past as a minimum visible date (.chartXScale). The X-axis shows 3 hours of data per screen width (.chartXVisibleDomain). The data points for the graph are generated once when screen is about to appear so that the Charts engine can use it (no lazy loading implemented yet). The line data points (LineMark views) consist of 2880 data points distributed every 5 minutes which simulates - two days of continuous data strea
I've been able to submit my app without issue so far until today, but it looks like app icon requirements either changed or being enforced differently? Validation failed Missing required icon file. The bundle does not contain an app icon for iPhone / iPod Touch of exactly '120x120' pixels, in .png format for iOS versions >= 10.0. To support older versions of iOS, the icon may be required in the bundle outside of an asset catalog. Make sure the Info.plist file includes appropriate entries referencing the file.

The Widget Image display on iOS26 transparency mode is blank Both of these writing methods show blank Spaces. Is there a problem with my code or a bug in the system? The current compilation environment is Xcode Version 16.3 (16E140) iOS26.0
Summary NetworkConnection in iOS 26 Network framework throws POSIXErrorCode(rawValue: 22): Invalid argument when receiving WebSocket ping (opcode 9) or pong (opcode 10) control frames. This prevents proper WebSocket keep-alive functionality. Environment iOS 26.0 (Simulator) macOS 26.1 Xcode 26.0 Note: This issue was initially discovered on iOS 26 Simulator. The same behavior was confirmed on macOS 26, suggesting a shared bug in the Network framework. The attached sample code is for macOS for easier reproduction. Description When using the new NetworkConnection API introduced in iOS 26 or macOS 26, the receive() method throws EINVAL error whenever a ping or pong control frame is received from the server. This is a critical issue because: WebSocket servers commonly send ping frames to keep connections alive Clients send ping frames to verify connection health The receive callback never receives the ping/pong frame - the error occurs before the frame reaches user code Steps to Reproduce Create a WebSock

The buttons in the navigation bar are not available in the element tree after iOS 26 upgrade of the test phones. The same IPA version, the same XCode version, but different trees on different phones. There is no way to automate UI testing for these missing buttons. # ios 18 NavigationBar, 0x108e0c3c0, {{0.0, 47.0}, {390.0, 44.0}}, identifier: 'Profile' Button, 0x108e0c500, {{8.0, 47.0}, {43.0, 44.0}}, identifier: 'UserProfileSceneViewController_profile_back_button', label: 'chevronLeftIcon' StaticText, 0x108e0c640, {{169.3, 58.0}, {51.3, 22.0}}, label: 'Profile' Button, 0x108e0c780, {{339.0, 47.0}, {43.0, 44.0}}, identifier: 'UserProfileSceneViewController_settings_bar_button', label: 'Settings' # ios 26 NavigationBar, 0x13d63c8c0, {{0.0, 47.0}, {428.0, 54.0}}, identifier: 'Profile' StaticText, 0x13d63ca00, {{188.3, 58.0}, {51.3, 22.0}}, label: 'Profile'
Hello I don't recommend trying to implement controller tracking & recasting using the controller's IMU data. ARKit in visionOS 26 has support for tracking 6DOF pose of PSVR2 controllers. Apple publishes a Unity plugin that bridges the native GameController + ARKit support for discovering and tracking spatial game controllers into Unity. See Apple.SpatialAccessory in the Apple unity plugins Github.

Still no luck, unfortunately. OSX version is 15.7.2. I created a new user account, and as such, needed to add the Developer ID Application and Developer ID Installer certificates for our organization to XCode. After building the application, I had it notarized using XCode's Organizer window via the Direct Distribution option. Unfortunately, the package installer still wrote a zero-byte application to the /Application folder. I verified the installer had the correct Payload by extracting and decompressing the package data. Quite the head scratcher. Thank you for any insight.

Thanks for providing some code. I was able to reproduce the problem you have described here. Our engineering teams need to investigate this issue, as resolution may involve changes to Apple's software. Please file a bug report, include a small Xcode project and some directions that can be used to reproduce the problem, and post the Feedback number here once you do. If you post the Feedback number here I'll check the status next time I do a sweep of forums posts where I've suggested bug reports. Bug Reporting: How and Why? has tips on creating your bug report.

I have a Unity AR project that I want to build for iOS. The build in Unity succeeds just fine, but when it opens in XCode, whatever I do, it keeps showing this error in GameAssembly: Command PhaseScriptExecution failed with a nonzero exit code. This error also doesn't open when choosing Reveal in Log. I have added the IL2CPP package in the Unity version, deleted and reentered scenes and no issue on Unity's side. On XCode I signed in with my developer account, tried deleting derived data, made a clean build and still the issue persists.
Thank you for your response and for taking the time to read the Technical Note. I believe you have now realized that Universal Links function consistently well, but there could be several reasons for their behavior deviating from expectations: When encountering issues related to Apple-app-site-association files and associated domains, particularly when they function correctly on the first attempt but fail on subsequent attempts within the same tab, several potential security and configuration factors could be at play: JavaScript Logic Errors: Although you mentioned that the code execution is identical, race conditions or state mismanagement within your JavaScript could lead to differing outcomes on successive runs. Please verify for such possibilities. Error Handling and Logs: Enhance error handling surrounding the associated domain validation logic and ensure comprehensive logging to capture any discrepancies during the second invocation. By systematically examining these areas, you should be able to identif

Thanks for the post and thank you for bringing this issue to our attention. Indeed, this is a known problem where SwiftUI control will need to resize a window with a NavigationSplitView generates Invalid view geometry warnings in Xcode. The issue is currently being investigated. If you would like to be notified when the fix is implemented and Xcode ceases to issue these warnings, we recommend filing a bug report. The warning looks something like this: Unable to simultaneously satisfy constraints. Probably at least one of the constraints in the following list is one you don't want. Try this: (1) look at each constraint and try to figure out which you don't expect; (2) find the code that added the unwanted constraint or constraints and fix it. (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to.. In the meantime, please be advised that the engineering team is actively addressing the warning issue. If you want to file a bug please post the FB number h
