The following code causes an error in Xcode 26.0 beta3 in iOS Simulator with iOS 26.0. After starting the App, scroll to the end of the grid and the app will break. Testet with Xcode Playground with platforms: [ .iOS(17.0)], Simplest possible variant: import SwiftUI import MapKit struct ContentView: View { var body: some View { NavigationStack { ScrollView { LazyVGrid(columns: [GridItem()]) { ForEach(1...12, id:.self) { i in Text(Hello (i)) .frame(height: 150) } Map { } .frame(height: 150) } } } } } Thrown error: Observation tracking feedback loop detected! Make a symbolic breakpoint at UIObservationTrackingFeedbackLoopDetected to catch this in the debugger. Refer to the console logs for details about recent invalidations; you can also make a symbolic breakpoint at UIObservationTrackingInvalidated to catch invalidations in the debugger.

I have the same issue, I'm not able to reach the same side bar appearance as the Settings app with UISplitViewController (tested on iOS 26 Beta 4). I've created a very basic double column split view controller and there isn't the Liquid Glass effect around the edges of the primary view controller. Interestingly, it does work if one uses the SwiftUI equivalent NavigationSplitView. So either it's a bug in UISplitViewController, or it's not planned for it to support that appearance (hopefully not!).

Is there a modifier to make section headers non-sticky? You can use the automatic .listStyle(.automatic) or opt for a lazy stack instead and apply your decorators. For examples, refer to Grouping data with lazy stack views. .listStyle(.automatic) results in in .insetGrouped, so that's a different look. I tried the LazyVStack approach and this worked well for a screen that was pretty custom-styled anyway. Side note: LazyVStack made me a little upset by applying the spacing not only between rows, but also after the section header; requiring dancing around with the spacing and paddings to get the correct look; I wished for a separation of spacing between sections, spacing between rows and spacing between [section header/rows/section footer]. But I'm wondering if this is a well-rounded approach for Views that just want a plain styled data list. It's certainly more feasible with the delicate separators-going-all-the-way-through-to-the-edge-of-the-screen gone in iOS 26, but still, custom-rebuilding all the Views wi

So, my current experience with this. I am advertising my ios app with Google Ads app campaign. Whenever user does this one thing on the app, I log an event to Firebase/Google Analytics. That event there shows up fine with proper count. Then I export this event to Google Ads, and also make a SKAdNetwork mapping. This event shows up in Google Ads as a conversion action definition, but with status No recent conversions. I want it to show Active. I have also set AppsFlyer to receive winning SKAN postback copies (its a bit easier to read them there in the SKAN Overview section). I do see the app instals there, meaning I am getting SKAN postback copies, but the column Null conversion value rate is always 100% - meaning, each received postback has conversion value as NULL. Now, it is my understanding, that in order to update that Conversion Value (CV), we have 2 approaches: Directly: SKAdNetwork.updatePostbackConversionValue(5) { error in if let error = error { // Report production error to Sentry } } Indir

I have been working to remediate PDFs for a client. The documents/forms have many tables. When I correctly tag a table, using Foxit Editor Pro, it works beautifully on a PC reading it with NVDA. On Mac using VoiceOver the table isn't accessible. It doesn't matter if I try to read it in Adobe Acrobat, Foxit, or Preview. The reader often says the document is empty, omits column headers, and/or associates the wrong header with the column data. The documents have essentially the same coding behind them as for the web. Why is it they perform so well on a PC with NVDA, but so poorly with Mac VoiceOver? I am a Quality Assurance Specialist. I review websites apps, and documents for accessibility. Why can't I do my job using only my Mac system? As a Mac user, it frustrates me that I can't use my preferred system for checking documents to see if they are accessible because VoiceOver doesn't work well. I actually have to recommend to my clients and their customers that they need to use a PC with NVDA o

Just a couple of factoids to expand on the previous answers… If your Apple Account is not a member of a paid developer team then Xcode lets you develop apps for your own device. This feature is known as a Personal Team. It has significant limitations. For the specifics, see Developer > Support > Choosing a Membership. If you’re using a Personal Team, it’s a good idea to bookmark the Developer Account Help > Reference > Supported capabilities (iOS) page. The last column, labelled Apple Developer, shows what entitlements are available to Personal Team developers. Sadly, Family Control is not in that list )-: Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = eskimo + 1 + @ + apple.com

I cannot explain how frustrating this is. Not that I want to compare to Android, but in 3 years of QA Testing my app, Android works like a dream, while iOS fights with me EVERY SINGLE STEP OF THE WAY. Hopefully someone here can tell me what I am missing/doing wrong/which god I must appease to get this to work. I have 3 REAL iPhones of varying iOS versions and ages. But they are all proper actual iPhones. We use google accounts at this company, so my primary email is a gmail one. I have created MANY sandbox accounts inside App Store Connect. Currently I have 2, and 2 of my devices (both 14's one of which is a Pro) have my Primary account as the main account for the device. But they both also have a Sandbox account which is simply my main email with a +sandbox in it to make it a new unique email. Here is the problem, nothing works as expected ever. I can install my Staging and Production apps from TestFlight, then I can make a subscription purchase as a customer would and I SHOULD see that subscription in my Sa
I just upgraded to Xcode 26 beta 3 and when I run my iPad app the toggle sidebar button is no longer visible when I set the column visibility to .detailOnly. I don't apply any modifiers to my NavigationSplitView. It looks like this. NavigationSplitView(columnVisibility: $sceneModel.columnVisibility) { GPSidebarView(appModels: self.appModels()) } detail: { GPRootContentViewIOS26(appModels: self.appModels()) } I also don't do .toolbar(removing: .sidebarToggle) anywhere in my code. Yesterday when I had Xcode 26 beta 2 the toggle sidebar button was there on my detail only view. I am trying to figure out if there is something that I did to break this and after looking at my git history the only thing I can see is that I upgraded Xcode 26. Here is what I get when I set the column visibility to .detailOnly. Then here is what I get when I set the column visibility to .doubleColumn.
My team has been debugging problems with the SwiftUI List component this week. We have found that it's performance is sub-optimal on iOS 16. You can see a simple grid of images, the scroll indicator stutters when scrolling down: Now compare it to what happens when we use a ScrollView with a LazyVStack: (An error occurred while uploading my second image, but pretend you see a scroll indicator moving smoothly down the side of the screen). You can see the scroll indicator moves smoothly without issue. We also found that the ScrollView combined with a LazyVStack properly calls onDisappear, which enables us to call a cancel method on the async image loading code that we use for our individual cells in this example. Though in a previous question, it was asserted that onDisappear cannot be reliably expected to be called in a List, I do not feel that answer is correct or proper behavior. Is this a bug, or is this expected behavior on a List? This is the cell that is being rendered: struct UserGridCell: View { let sta
Has anyone else noticed that macOS Sequoia 15.5 has a regression in SwiftUI Table scrolling performance? I have complex Tables in a SwiftUI app and they scroll adequately on macOS 15.4.1 but hang, beachball, and stutter while scrolling on macOS 15.5. The exact same build is running in both cases. (I've even reduced the table to three simple columns of text and STILL fail to get entirely smooth scrolling on macOS 15.5.) It's like someone just fundamentally broke Table on macOS. Has anyone else encountered this?

We are preparing builds using Xcode 16.0 given we have a large set of users on iOS 12. Now we have doubts wether we will run into issues if we ship using it (even if it compiles, archives and uploads successfully) given the table columns and content has changed since the last time we checked this table: https://developer.apple.com/support/xcode/. 1- Is the Deployment Targets range for Xcode 16 value correct for iOS? (On the 24th of February it had iOS 12-18, now it has iOS 15-18) 2- Are we OK to ship for iOS 12 using xcode 16.3? Thanks, Joao Garcia

I've observed a difference in the layout of menu items within ContextMenu and Menu when comparing system applications to my own SwiftUI app, specifically concerning the order of icons and titles. On iOS 26, system apps (as shown in the image in the System App column) appear to display the item's icon before its title for certain menu items. However, in my SwiftUI app, when I use a Label (e.g. Label(Paste, systemImage: doc.on.clipboard)) or an HStack containing an Image and Text, the icon consistently appears after the title within both ContextMenu and Menu items. I'm aiming to achieve the icon first, then title layout as seen in system apps. My attempts to arrange this order using HStack directly within the Button's label closure: Menu { Button { /* ... */ } label: { HStack { Image(systemName: doc.on.clipboard) Text(String(localized: Paste)) } } // ... } label: { Text(タップミー) } seem to be overridden or restricted by the OS, which forces the icon to the leading position (as shown in the image in the Cu
Thanks for the update, this helps to address the issue. The Four Freedoms^H^H^H^H^H^H^H^H Functions section. In that model, the content column of a row is encrypted (based on the kSecAttrAccessible column) but that doesn’t stop you from deleting the entire row.
