Paste button on navigation bar is not shown on iOS/iPadOS 26
The Paste button (using UIPasteControll) located on UINavigationBar is not shown at application startup on iOS/iPadOS 26. This issue will disappear when device is rotated or window size is changed. And this issue does not occur on iOS / iPadOS 18 and earlier. I uploaded the sample project to github at the following URL. https://github.com/gpn-galapagos/PasteButtonApp.git Has anyone had the same issue or knows a workaround?

Running tests on multiple simulators and local mock servers
Hello, I have a question about running tests on multiple simulators. Currently, my company has a WDIO+Appium test suite with XCUITEST driver that runs on a single simulator through a mockttp proxy (we are intercepting and mocking some of the responses from our APIs and pass through the rest). In order to route the traffic we are currently using 'networksetup -setsecurewebproxy '. Everything works as expected. With growing number of tests we'd like to scale number of simulators on a single host to 3-5. We have a working setup but the problem are system-wide proxy settings routing traffic from multiple simulators, which we can't distinguish by UDID or any other means, we know of. We can spin multiple mock servers on the same machine but we are struggling to find the way to route the traffic on a simulator basis. In the end, both options are viable: 1 mock server running for multiple simulators N number of mock servers for N number of simulators Has anyone had the same/similar problem? How to approach this? We are currently running on Sequoia OSX and platform version 18.6. Thanks!

init(data: Data) for SwiftUI Image?
Is there any reason why the SwiftUI Image hasn’t a direct init(data: Data) like UIImage from UIKit? In my opinion it’s very unintuitive and expensive to create a UIImage in the first step to create a SwiftUI Image with Image(uiImage: UIImage) in the second step. In addition to that, this causes unnecessary UIKit imports. In my opinion this is a very obvious small in the API, so are there any reasons why it is what it is? Best regards

Text with .secondary vanishes when Material background is clipped to UnevenRoundedRectangle in ScrollView
I just found a weird bug: If you place a Text view using .foregroundStyle(.secondary), .tertiary, or other semantic colors inside a ScrollView, and apply a Material background clipped to an UnevenRoundedRectangle, the text becomes invisible. This issue does not occur when: The text uses .primary or explicit colors (e.g., .red, Color.blue), or The background is clipped to a standard shape (e.g., RoundedRectangle). A minimal reproducible example is shown below: ScrollView{ VStack { Image(systemName: "globe") .imageScale(.large) .foregroundStyle(.tint) Text("Hello World.") .font(.system(size: 15)) .foregroundStyle(.quinary) } } .padding() .frame(height: 100) .background(Material.regular) .clipShape(UnevenRoundedRectangle(topLeadingRadius: 10,bottomLeadingRadius: 8,bottomTrailingRadius:8, topTrailingRadius: 8))

The Nightmare of Small Toolbar Icons
When building in Xcode on MacOS Tahoe, it seems it is no longer possible to dynamically specify a "small" size toolbar for NSToolbar/NSToolbarItem. It works in MacOS code compiled and linked on earlier systems. I don't want to use "SFSymbol", or "templates". I have over 60 custom-made .png toolbars, in individual Image Set files, at the previous requisite sizes of 24x24 / 48x48, and 32x32 / 64x64. Sure -- I can configure an NSToolbar with whatever size .png assets I want. I just can't dynamically switch between the two groups of sizes. According to the Apple Coding Assistant, the only solution is to change the image names of each of the NSToolbarItems at runtime. OK -- but even when attempting that, the NSToolbarItems refuse to take on their smaller size... ...unless: they are attached to a custom view NSToolbarItem with an NSButton of style "Bevel". I have about 10 of those, and YES -- I CAN change those to a "small" size. Is this REALLY what I'm forced to do?! The Apple Coding Assistant just runs me around in circles, making coding suggestions that include properties that don't exists. I've gone around and around on these issues for over a week -- it can't be this hard, right? Is there no way to make multiple NSToolbar objects, one for "large" and one for "small"?

UIDocumentPickerViewController provides corrupt copy of file when user taps multiple times on file
We're trying to implement a backup/restore data feature in our business productivity iPad app using UIDocumentPickerViewController and AppleArchive, but discovered odd behavior of [UIDocumentPickerViewController initForOpeningContentTypes: asCopy:YES] when reading large archive files from a USB drive. We've duplicated this behavior with iPadOS 16.6.1 and 17.7 when building our app with Xcode 15.4 targeting minimum deployment of iPadOS 16. We haven't tested this with bleeding edge iPadOS 18. Here's our Objective-C code which presents the picker: NSArray* contentTypeArray = @[UTTypeAppleArchive]; UIDocumentPickerViewController* docPickerVC = [[UIDocumentPickerViewController alloc] initForOpeningContentTypes:contentTypeArray asCopy:YES]; docPickerVC.delegate = self; docPickerVC.allowsMultipleSelection = NO; docPickerVC.shouldShowFileExtensions = YES; docPickerVC.modalPresentationStyle = UIModalPresentationPopover; docPickerVC.popoverPresentationController.sourceView = self.view; [self presentViewController:docPickerVC animated:YES completion:nil]; The UIDocumentPickerViewController remains visible until the selected external archive file has been copied from the USB drive to the app's local tmp sandbox. This may take several seconds due to the slow access speed of the USB drive. During this time the UIDocumentPickerViewController does NOT disable its tableview rows displaying files found on the USB drive. Even the most patient user will tap the desired filename a second (or third or fourth) time since the user's initial tap appears to have been ignored by UIDocumentPickerViewController, which lacks sufficient UI feedback showing it's busy copying the selected file. When the user taps the file a second time, UIDocumentPickerViewController apparently begins to copy the archive file once again. The end result is a truncated copy of the selected file based on the time between taps. For instance, a 788 MB source archive may be copied as a 56 MB file. Here, the UIDocumentPickerDelegate receives a 56 MB file instead of the original 788 MB of data. Not surprisingly, AppleArchive fails to decrypt the local copy of the archive because it's missing data. Instead of failing gracefully, AppleArchive crashes in AAArchiveStreamClose() (see forums post 765102 for details). Does anyone know if there's a workaround for this strange behavior of UIDocumentPickerViewController?

listRowSeparatorTint not updated
This sample code exhibits two issues: struct ContentView: View { @State private var myColor = Color.red var body: some View { VStack() { List() { Text("Object") Text("Object") Text("Object") .listRowSeparatorTint(myColor) Text("Object") } Button(action:{myColor = Color.green}) {Text("Change color")} } .foregroundColor(myColor) } } the row separator isn't redraws when the @State property change listRowSeparatorTint apply to two lines The first point is really disappointing. Is there anyone which know if this is a bug or there is a more correct way to use listRowSeparatorTint with changing parameter?

Using .glassEffect in Charts
Hi, I was wondering if it's possible (and advisable) to use the new glass effects available in iOS 26 in Swift Charts? For example, in a chart like the one in the image I've attached to this post, I was looking to try adding a .glassEffect modifier to the BarMarks to see how that would look and feel. However, it seems it's not available directly on the BarMark (ChartContent) type, and I'm having trouble adding it in other ways too, such as using in on the types I supply to modifiers like foregroundStyle or clipShape. Am I missing anything? Maybe it's just not advisable or necessary to use glass effects within Charts?

encounter memory leak for SVG image
I have a memory leak for SVG image that located in Assets.xcassets file when using SwiftUI Image, but when I use UIImage then convert it to SwiftUI Image the issue is not found. import SwiftUI struct ContentView: View { var body: some View { NavigationStack { VStack { NavigationLink("Show", destination: SecondView()) } .padding() } } } struct SecondView: View { @Environment(\.dismiss) var dismiss var body: some View { NavigationStack { VStack { IM.svgImage .resizable() .scaledToFit() .frame(width: 200, height: 200) Button("Dismiss") { dismiss() } } } } } enum IM { static let testImage: Image = "test_image".image static let svgImage: Image = "svgImage".image } extension String { var image: Image { Image(self) // Memory leak } var imageFromUIImage: Image { guard let uiImage = UIImage(named: self) else { return Image(self) } return Image(uiImage: uiImage) // No Memory leak } } Environment that produces the issue: Xcode: 16.2 Simulator: iPhone 15 Pro (iOS 17.5)

UINavigationController retain cycle in iOS 26
Verbatim of a feedback report (FB18431713) I submitted, duplicated here since we can't see each other's feedbacks, and I wanted a centralized place to track the resolution of this as I'm surely not the only one facing this. When building the app using Xcode 26 beta 2 and running it in an iOS 26 simulator, I'm experiencing a retain cycle in the UINavigationController. From the data I saw in Xcode's memory graph debugger, it seems that _UIViewControllerOneToOneTransitionContext is retaining it. I base this on the fact that the line connecting a view controller and _UIViewControllerOneToOneTransitionContext has a "strong" reference, as indicated in Xcode. (However, I'm reporting this as a retain cycle in UINavigationController, as that's what seems to hold onto this transition-context.)

Landscape safe area is incorrect when presenting SKStoreProductViewController
Hi. If the app is in landscape only and when the SKStoreProductViewController is presented, the safeArea changes to what looks like a portrait mode safe area. When the SKStoreProductViewController is dismissed, the safeArea does NOT revert back to the original values. Is there a way to force the safeArea to "reset"? I've submitted some bug tickets through Apple Feedback but I haven't received any response about it. The below code will pop up the SKStoreProductViewController and if you have a UIView that is constrained to the safe area, then you can visibly notice that the safe area is changed and doesn't go back. I have tested this on iPhone 14 Pro, iPhone 15, and iPhone 16 Pro and in the Simulators. The incorrect behavior happens on those and probably more. Thanks. #import "ViewController.h" #import <StoreKit/StoreKit.h> @interface ViewController () @property (nonatomic, strong) SKStoreProductViewController *productViewController; @end @implementation ViewController - (IBAction)buttonTapped:(id)sender { self.productViewController = [[SKStoreProductViewController alloc] init]; NSDictionary *parameters = @{ @"id" : @"6443575749" }; [self.productViewController loadProductWithParameters:parameters completionBlock:^(BOOL result, NSError * _Nullable error) { [self presentViewController:self.productViewController animated:YES completion:^{ // presented // The panel that is constraint to the safe area visibly shows that the safe area is no longer correct. }]; }]; } @end

Get MacOS menubar size in Swift
To get menubar size, we can call. let menuBarHeight = NSStatusBar.system.thickness That is returning 24 and it is the same as my external screen. I did command + shift + 5 and use the screen capture tool to rougly measure the size of menubar. It is roughly 24px. However, for my macbook pro 14 inches m2 pro. The menubar seem thicker because of the webcam. Is there a way to find out the size in Swift?

Issues with .zoom NavigationTransition to a sheet with a .medium detent
When using a .zoom navigation transition, where .matchedTransitionSource is applied to a button in a toolbar and the destination view is a sheet which is presented with PresentationDetent.medium, the transition works initially, but shortly after it completes, the sheet's background is dimmed and the text of the source button reappears abruptly. Code and a screenshot are below, though the effect is best observed when interacting with the view. // // ContentView.swift // ZoomNavigationTransitionSample // // Created by Matthew DuBois on 6/15/25. // import SwiftUI struct ContentView: View { @State private var isPresentingSheet = false @Namespace private var namespace var body: some View { NavigationStack { List { Text("Some content") } .navigationTitle("Sample") .toolbar { ToolbarItem(placement: .topBarTrailing) { Button("Button") { isPresentingSheet = true } .matchedTransitionSource(id: "button", in: namespace) } } .sheet(isPresented: $isPresentingSheet) { Text("Some sheet content") .navigationTransition(.zoom(sourceID: "button", in: namespace)) .presentationDetents([.medium]) } } } } #Preview { ContentView() }

Cursor Misalignment When Selecting List Options – macOS Tahoe 26.0 Developer Beta 2
Since updating my MacBook Air to macOS Tahoe 26.0 Developer Beta 2, I’ve encountered a persistent cursor misalignment issue: When interacting with lists or contextual menus, the cursor’s visual position does not align with what it actually selects. The system registers the cursor slightly above where it appears, causing clicks to select the wrong option or fail to register. As a temporary workaround, I can sometimes position the cursor off-target and press Enter to select, but this is a frustrating and inefficient workaround. The issue persists after a restart and appears across multiple areas of the OS: Right-clicking an app in the Dock to open the contextual menu → cursor highlights an incorrect item relative to its position. In System Settings menus. Even on the Feedback Assistant site when selecting issue categories. Steps to Reproduce: 1️⃣ Update to macOS Tahoe 26.0 Developer Beta 2 on MacBook Air. 2️⃣ Right-click on any open application in the Dock. 3️⃣ Attempt to select an option from the list that appears. 4️⃣ Observe that the cursor highlights or interacts with a different option than where the cursor is visibly located. Notes: Issue is consistent across reboots. Affects workflow and general navigation. Temporary workaround using keyboard navigation is insufficient for productivity. FB Number: FB18531124 If others are seeing this as well, please confirm below so Apple can prioritize investigation.

iPadOS Floating Tab Bar Items (unselected) use Black Text - Unreadable with App Black Background (Dark Mode): UIKit App
Reference Feedback FB19152594 Occurs with my 3rd Party UIKit App called "Lifeorities". Latest occurrence was 7/27/25 at 13:49 pm. Launch app (actual device running iPadOS 26 or iPadOS 26 simulator) Initial screen displays view content and floating tab bar at top of screen (both portrait orientation and landscape). Floating tab bar items respond to liquid glass effect (but liquid glass appearance of the whole tab bar doesn't comply with new glass pill shaped tab bar area). Selected tab bar item obeys selected app designated color (assets). Unselected tab bar items are using black text which is unreadable on app background which used dark mode as default (as intended). Selecting another tab bar item shows the liquid glass effect as you navigate to the new tab bar item and shows the app designated color (assets). Previous tab bar item that was selected, now is unselected and shows black text. NOTE: iOS tab bar items work fine (show white foreground color as desired for unselected tab bar items).

NSRulerView's background color and transparency (macOS 26)
When I compiled my legacy project with Tahoe's macOS 26 SDK, NSRulerViews are showing a very different design: Under prior macOS versions the horizontal and verrical ruler's background were blurring the content view, which was extending under the rulers, showing through their transparency. With Tahoe the horizontal ruler is always reflecting the scrollview's background color, showing the blurred content view beneath. And the vertical ruler is always completely transparent (without any blurring), showing the content together with the ruler's markers and ticks. It's difficult to describe, I'll try to replicate this behavior with a minimal test project, and probably file a bug report / enhancement request. But before I take next steps, can anyone confirm this observation? Maybe it is an intentional design decision by Apple?
