There appears to be a bug in Link with IPv4 addresses with padding in the second octet, on macOS and iOS both. struct LinkViewBug: View { let works = URL(string: http://172.16.1.1)! let alsoWorks = URL(string: http://172.16.001.001)! let doesntWork = URL(string: http://172.016.001.001)! let alsoDoesntWork = URL(string: http://172.016.1.1)! var body: some View { // destination -> http://172.16.1.1 Link(works.formatted(), destination: works) Link(alsoWorks.formatted(), destination: alsoWorks) // destination -> http://172.14.1.1 ? Link(doesntWork.formatted(), destination: doesntWork) Link(alsoDoesntWork.formatted(), destination: alsoDoesntWork) } }

In macOS 26, there is a new property on NSControl called .borderShape. The WWDC 2025-310 video says it can be used to Override preferred shape of control to suit your design. and that it's available on NSButton, NSPopUpButton and NSSegmentedControl. Is there an equivalent to that property for SwiftUI? For example, given the following SwiftUI code: Button(Eject) { } .borderShape(...) <-- ? How can I apply a .borderShape that would match those on controls created in AppKit? I'm aware that SwiftUI offers a plethora of ways to custom design a button such that it can have rounded corners, but I'm interested in this particular property so that SwiftUI buttons and AppKit buttons in the same app have the same look-and-feel.

I am reporting a reproducible performance issue in iOS 18.6 where synchronizing the scroll position of two Chart views via chartScrollPosition(id:) causes a complete redraw loop when custom AxisMarks are used. This occurs even when the axis marks are technically hidden, leading to significant frame drops and stuttering on modern hardware like the iPhone 15. Environment Device: iPhone 15 OS: iOS 18.6 (22G86) Frameworks: SwiftUI, Swift Charts, Observation The Issue When using a shared @Observable state to sync two charts, the scrolling is fluid only if the axes are at their default settings. As soon as a custom AxisMarks block is added to either chart, the following behavior is observed: Diffing Failure: The framework appears unable to maintain the identity of the axis components during the scroll update. Redraw Loop: Instead of an incremental scroll translation, the diffing algorithm triggers a full reload/re-render of both charts on every scroll offset change. Impact: CPU spikes to 100% and the UI be

My app is a UIKit app with a lot of SwiftUI mixed in. A common scenario is that a UIViewController presents a sheet with a SwiftUI view wrapped in a UIHostingController. When I present the exact same SwiftUI View it looks different in a SwiftUI sheet compared to when it's wrapped in a UIHostingController and presented from a view controller. I'm using a hacky workaround in which I loop through all subviews of the hosting controller in viewWillLayoutSubviews and look for a NavigationStackHostingController to manually set the background color, but it feels like it could brake easily. Has anyone found a better way to fix this? Feedback: FB22028838

On macOS 26.3, Xcode 26.3, why does a labelStyle of titleAndIcon not show both the title and the icon of a label? The label styles iconOnly and titleOnly behave as expected. Picker(Label Demo, selection: $selectedItem) { Label { Text(File) } icon: { Image(systemName: doc) } Label { Text(Folder) } icon: { Image(systemName: folder) } } .labelStyle(.titleAndIcon) .pickerStyle(.segmented) Note that there is no icon shown. Placing the .labelStyle modifier in different places has no effect. The icon is correctly shown when the labelStyle is set to .iconOnly. An NSSegmentedControl created with AppKit and presented in an NSViewRepresentable does correctly show titles and icons if configured appropriately. Tested on: macOS 26.3 (25D125) Xcode 26.3 (17C519) A brand new SwiftUI macOS App project.

My app Mocawave is a music player distributed through the Mac App Store. It declares specific audio document types (public.mp3, com.microsoft.waveform-audio, public.mpeg-4-audio, public.aac-audio) in its CFBundleDocumentTypes with a Viewer role. When a user sets Mocawave as the default app for audio files and double-clicks an MP3 downloaded from the internet (which has the com.apple.quarantine extended attribute), macOS displays the alert: Apple could not verify [filename] is free of malware that may harm your Mac or compromise your privacy. This does not happen when: Opening the same file via NSOpenPanel from within the app Opening the same file with Apple's Music.app or QuickTime Player The app is: Distributed through the Mac App Store Sandboxed (com.apple.security.app-sandbox) Uses com.apple.security.files.user-selected.read-write entitlement The file being opened is a regular audio file (MP3), not an executable. Since the app is sandboxed and distributed through the App Store, I expected it to have suffic

I’ve encountered an aspect of the Liquid Glass effect in SwiftUI that seems a bit odd: the Liquid Glass interaction appears to ignore regular hit-testing behavior. The following sample shows a button with hit testing disabled: @main struct LiquidGlassHitTestDemo: App { var body: some Scene { WindowGroup { Button(Liquid) { fatalError(Never called.) } .buttonStyle(.glassProminent) .allowsHitTesting(false) } } } As expected, the button’s action is never called. However, the interactive glass effect still responds to touch events: What’s even more surprising is that the UIKit equivalent behaves differently: final class ViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() let button = UIButton( configuration: .prominentGlass(), primaryAction: UIAction( title: Liquid, handler: { action in print(Never called.) } ) ) view.addSubview(button) button.translatesAutoresizingMaskIntoConstraints = false NSLayoutConstraint.activate([ button.centerXAnchor.constraint(equalTo: view.cente
