Overview

Hi everyone! I've encountered an issue on Mac Catalyst: using the latest inspector modifier causes abnormal Sidebar and Columns state in NavigationSplitView. Sample Code: struct ContentView: View { @State private var isPresented = false var body: some View { NavigationSplitView { List { ForEach(0..<20, id: \.self) { item in Text("Item \(item)") } } } content: { List { ForEach(0..<20, id: \.self) { item in Text("Item \(item)") } } } detail: { List { } } .inspector(isPresented: $isPresented) { Form { } } } } Steps to reproduce: Xcode 16 beta 7, create a new iOS project Paste the code above Enable Mac Catalyst Run on Mac (macOS 15 beta 9) Press Command+N three times to open 3 new windows Click the Sidebar Toggle button The issue occurs (see screenshot below) Through testing, I found that as long as the inspector modifier is attached, the issue occurs. Also, the problem only appears in the 3rd and subsequent newly opened windows—the first two windows work as expected. FB20061521

There’s still debate on what drives App Store rankings, but some confirmed factors include app name, subtitle, keyword field, downloads, ratings, and in-app events. Likely influences are stability, retention, conversion rate, and user behavior. Search relies most on metadata, Top Charts focus on download velocity, and Featured spots are editorially chosen. Elements like promo text, long description, and release notes don’t impact rankings.

I’m trying to clarify keyword usage in App Store Optimization. Apple’s docs suggest you can use phrases like “Near Me” instead of separating words with commas (“Near,Me”). Does assigning phrases directly improve ranking compared to letting Apple combine single keywords?

One screen in my app uses a navigation bar with some buttons added to the titleView and some buttons added as a customView of a single rightBarButtonItem. In iOS 26 (beta 9), if I switch to the home screen and back again, the titleView and rightBarButtonItem disappear and an overflow button (three dots) appears instead. Nothing happens when I click the overflow button. Here's a screen capture: https://youtu.be/tthRnMz98kA This also happens when I switch to another app, when I rotate the device or when I resize the app window. In all cases, there is enough room to show all the buttons, but they still disappear. I overrode the viewWillTransition function in my view controller and logged when that runs. I can see that if I switch to the home screen and back again before that runs (within one or two seconds), there's no problem. But once that runs, the navigation bar items disappear and the overflow button appears. I have not done anything to set up the overflow button and don't have any need to use it. The documentation about it isn't very detailed, but it seems like it shouldn't be used unless I add it. This wasn't a problem in iOS 18 or earlier iOS versions. Does anyone know how to stop this? BTW, I'm using Swift, but not SwiftUI.

hi, When changing the map to Satellite in Apple Maps and centering it on Ōmuta City, Fukuoka Prefecture, Japan (as shown in the image), the app crashes when swiping to the right. This issue also occurs in MapKit, and I confirmed it happens in Apple Maps as well. It seems that either the satellite map tiles are missing or an error is occurring. Our application is experiencing a crash, and this has become a serious issue. Since September 1, crashes have increased significantly. Initially, we suspected that the issue was due to our application’s implementation, but our investigation revealed that the problem lies with the map tiles being called through MapKit. Could you please investigate this issue and provide a fix?

With the RC version of macOS 26, an issue persists when you try to create a bookmark with security scope for the root folder "/". This leads to an error "The file couldn’t be opened.". However, you can create bookmark for /Applications, /System, /Users... This is quite annoying for one of my app because a user can create a cartography of his disk usage, and the access to the root folder "/" is the only way to do so! Is there a workaround? PS: reported the issue with ID FB20186406 let openPanel = NSOpenPanel() openPanel.canChooseDirectories = true openPanel.canChooseFiles = false openPanel.beginSheetModal(for: self.view.window!) { (result) in guard result == .OK, let folderURL = openPanel.url else { return } openPanel.close() do { let data = try folderURL.bookmarkData(options: .withSecurityScope, includingResourceValuesForKeys: nil, relativeTo: nil) print("Bookmark data was created for \(folderURL.path)") } catch (let error) { print("Error creating bookmark for \(folderURL.path), with error: \(error.localizedDescription)") } }

My app start up has became horrid. It takes 1 minute to open SQLlite database for my rust core. Impossible to work... I have Address Sanitizer, Thread Perf Checker and Thread Sanitizer disabled...

.popover(isPresented: modifier doesn't work on Mac Catalyst when attached to the item in the toolbar. The app crashes on button click, when trying to present the popover. iOS 26 RC (macOS 26 RC) Feedback ID - FB20145491 import SwiftUI struct ContentView: View { @State private var isPresented: Bool = false var body: some View { NavigationStack { Text("Hello, world!") .toolbar { ToolbarItem(placement: .automatic) { Button(action: { self.isPresented.toggle() }) { Text("Toggle popover") } .popover(isPresented: $isPresented) { Text("Hello, world!") } } } } } } #Preview { ContentView() }

With iOS 26 the CPListSection header has a transparent background, and when the list scrolls under the header it doesn't look good at all. We expected to see a glass fading effect maybe, like the one on the top of the screen. Is it a known bug?

Hello everyone. Hope this one finds you well) I have an issue with integrating a FIDO2 server with ASAuthorizationController. I have managed to register a user with passkey successfully, however when authenticating, the request for authentication response fails. The server can't validate signature field. I can see 2 possible causes for the issue: ASAuthorizationPlatformPublicKeyCredentialAssertion.rawAuthenticatorData contains invalid algorithm information (the server tries ES256, which ultimately fails with false response), or I have messed up Base64URL encoding for the signature property (which is unlikely, since all other fields also require Base64URL, and the server consumes them with no issues). So the question is, what encryption algorithm does ASAuthorizationController use? Maybe someone has other ideas regarding where to look into? Please help. Thanks)

I have a FORD F250 2021. I returned for a deployment, and CarPlay does not work in my vehicle. I have tried all the YouTube, TikTok, Facebook, and Instagram videos I could find. They all actually started to repeat, so I decided to come here. My wife has an iPhone 16 Pro Max, and it connects to CarPlay without any issues. Other than all the social media suggestions, do you have any other suggestions? No, I am not ready to purchase a new device.

I've been trying to use Antrhopic with Xcode 26 RC and continue to run into this error: No Data/Bytes for request: https://api.anthropic.com/v1/messages Once I get it, all prompts fail even a simple "Hello" that worked a moment ago returns the error message. Restarting Xcode and it returns to normal till I hit that error again. Any ideas on what's going on?

We tested call blocking on iOS 26 and noticed something strange: the call will not be blocked if an outgoing call was made to its number before. Nevertheless, it will be blocked if we delete the outgoing call record from the Phone.app Recents. This behavior looks like a bug and is unexpected when using our application. Was this a planned callkit change in iOS 26? Is it possible to get the correct call blocking behavior back? We set blocking rules with addBlockingEntry(withNextSequentialPhoneNumber:) and this problem is not present in iOS 18 and earlier. Thank you in advance

We set the CVDisplayLink on macOS to 0 or 120, and get the following. This then clamps maximum refresh to 60Hz on the 120Hz ProMotion display on a MBP M2 Max laptop. How is this not fixed in 4 macOS releases? CoreVideo: currentVBLDelta returned 200000 for display 1 -- ignoring unreasonable value CoreVideo: [0x7fe2fb816020] Bad CurrentVBLDelta for display 1 is zero. defaulting to 60Hz.

Hi, I have an app that displays tens of short (<1mb) mp4 videos stored in a remote server in a vertical UICollectionView that has horizontally scrollable sections. I'm caching all mp4 files on disk after downloading, and I also have a in-memory cache that holds a limited number (around 30) of players. The players I'm using are simple views that wrap an AVPlayerLayer and its AVPlayerItem, along with a few additional UI components. The scrolling performance was good before iOS 26, but with the release of iOS 26, I noticed that there is significant stuttering during scrolling while creating players with a fileUrl. It happens even if use the same video file cached on disk for each cell for testing. I also started getting this kind of log messages after the players are deinitialized: <<<< PlayerRemoteXPC >>>> signalled err=-12785 at <>:1107 <<<< PlayerRemoteXPC >>>> signalled err=-12785 at <>:1095 <<<< PlayerRemoteXPC >>>> signalled err=-12785 at <>:1095 There's also another log message that I see occasionally, but I don't know what triggers it. << FigXPC >> signalled err=-16152 at <>:1683 Is there anyone else that experienced this kind of problem with the latest release? Also, I'm wondering what's the best way to resolve the issue. I could increase the size of the memory cache to something large like 100, but I'm not sure if it is an acceptable solution because: 1- There will be 100 player instance in memory at all times. 2- There will still be stuttering during the initial loading of the videos from the web. Any help is appreciated!

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=NSCocoaErrorDomain Code=4099 "The connection to service named com.apple.dmd.policy was invalidated: failed at lookup with error 159 - Sandbox restriction."

Why is Quicklook all of a sudden so slow? It used to be almost instant in macOS 15. I created FB20268201. import Cocoa import Quartz @main class AppDelegate: NSObject, NSApplicationDelegate, QLPreviewPanelDataSource, QLPreviewPanelDelegate { var url: URL? func applicationDidFinishLaunching(_ notification: Notification) { let openPanel = NSOpenPanel() openPanel.runModal() url = openPanel.urls[0] QLPreviewPanel.shared()!.makeKeyAndOrderFront(nil) } override func acceptsPreviewPanelControl(_ panel: QLPreviewPanel!) -> Bool { return true } override func beginPreviewPanelControl(_ panel: QLPreviewPanel!) { panel.dataSource = self panel.delegate = self } override func endPreviewPanelControl(_ panel: QLPreviewPanel!) { panel.dataSource = nil panel.delegate = nil } func numberOfPreviewItems(in panel: QLPreviewPanel!) -> Int { return 1 } func previewPanel(_ panel: QLPreviewPanel!, previewItemAt index: Int) -> QLPreviewItem! { return url as? QLPreviewItem } }

Looking to see if anyone has experienced this issue, and is aware of any workarounds. With an app migrating towards SwiftUI Views but still using UIKit for primary navigation, my app makes use of UIHostingController to push SwiftUI Views onto a UINavigationController stack in a lot of areas. With iOS 26, I notice that SwiftUI's Menu view really struggles to present when contained in a UIHostingController. An error is logged to the console on presentation, and depending on the UI, the Menu won't present inside of it's container, or will jump around the screen. The bug, it seems is based in a private class UIReparentingView and I am curious if anyone has found a work around for this issue. The error reported is: Adding '_UIReparentingView' as a subview of UIHostingController.view is not supported and may result in a broken view hierarchy. Add your view above UIHostingController.view in a common superview or insert it into your SwiftUI content in a UIViewRepresentable instead. The simplest way to see this issue is to create a new storyboard based project. From the ViewController present a UIHostingController with a SwiftUI view that has a Menu and then simply tap to open the Menu. Thanks for any input!

Hello, Are there any plans to compile a python 3.13 version of tensorflow-metal? Just got my new Mac mini and the automatically installed version of python installed by brew is python 3.13 and while if I was in a hurry, I could manage to get python 3.12 installed and use the corresponding tensorflow-metal version but I'm not in a hurry. Many thanks, Alan

I am trying to learn Xcode and swift ui for a class project but the attribute inspector just does not show up, I can have the simulator open or closed I click on it nothing works. I feel so stupid. I suppose you don't need it but it helps a lot. anyone have any trouble shooting that could help?
