Hello. I'm making an app with several different views. I'm trying to switch views using a button but I can't seem to figure out how. I know Navigation Links work, but my case doesn't work. The reasons for this are because I need to run other code when they click the button and I don't want them to be able to navigate back (to CustomizationView/CreateAccountView). I know that you can hide the back button but my problem with that is the fact that i will be navigating to a view (MainView) that will also have navigation buttons in it, so if i'm thinking correctly, the button will be hidden but when they press the next navigationlink (in MainView) it will show again and then they can go back (to CustomizationView/CreateAccountView). i don't want them to go back because they will be navigating from a login/account view that wont be needed anymore. I'm currently using .fullScreenCover() and it works fine except for performance (I'm assuming). here's the code: import SwiftUI struct CustomizationView: View {

Hi all, very new developer trying to build my own app. The app works, just trying to improve it. I’m implementing a Live Activity in a widget extension (Swift/SwiftUI) for an app built with Flutter as the host app. ActivityKit is functioning correctly—activities start, update, and end normally, and the widget extension receives all state updates. However, the Live Activity UI renders as a completely black capsule (both compact and expanded Dynamic Island, as well as the Lock Screen presentation). The system shows the Live Activity container, but none of the SwiftUI content displays. Verified so far: ActivityAttributes contains at least one stored property (previously empty). ContentState fully Codable + Hashable. All Dynamic Island regions return visible test UI (Text/Image). No .containerBackground() usage. Added explicit .activityBackgroundTint() + system foreground colors. All Swift files included in widget extension target. No runtime errors, no decode failures, no SwiftUI logs.

I’m working on a SwiftUI screen where I need to hide a header when the user scrolls down and show it again when the user scrolls up. I’m currently using a ScrollView combined with GeometryReader to detect scroll offset changes and update state variables like isScrolling or isScrollingDown. The issue is that the behavior is inconsistent. When I scroll down, the header hides correctly, but when I scroll back up, the header often doesn’t appear again even though the offset is changing. Sometimes the header comes back with a delay, and other times it never appears at all. Along with this, I’m also seeing noticeable UI lag whenever I try to calculate content height or read multiple geometry values inside the ScrollView. It looks like the frequent state updates inside the scroll offset tracking are causing layout recalculations and frame drops. I’ve tried placing the header in different positions (inside a ZStack aligned to the top, inside the VStack above the ScrollView, and with transitions like .push(fr

[Submitted as FB21078443] When using .matchedTransitionSource with .navigationTransition(.zoom), swiping back from the left edge to return from a detail view causes the source item to disappear once the transition finishes. It’s only a visual issue—the item is still there and can be tapped to open again. This doesn’t happen when using the Back button; only the swipe-back gesture triggers it. Also, it only reproduces on a physical device, not in Simulator.

A MacOS SwiftUI app using WindowGroup with a NavigationStack results in having the navigation title overlay the back button. Note that this does not occur if a tabbed interface is used. The work around is simply to hide the navigation bar back button and add a tool bar item that is custom back button. I found a fix on this forum, and it was similar to: #if os(macOS) .navigationBarBackButtonHidden(true) .toolbar { ToolbarItem(placement: .navigation) { Button(action: { dismiss() }) { Label(Back, systemImage: arrow.left.circle) } } } #endif modifying the NavigationLink targets and where the dismiss() function was provided by: @Environment(.dismiss) private var dismiss Is there any means to sign up for a notification to inform me that this bug has been fixed?

I’m trying to implement smooth zoom and drag interactions for an image on watchOS—similar to the Photos app. DTS recommended using digitalCrownRotation + scaleEffect in SwiftUI, and ChatGPT also suggests a similar approach. However, the experience still isn’t as smooth or polished as the Photos app. Before I commit fully to this direction, I want to confirm: 1. Is SwiftUI with digitalCrownRotation, scaleEffect, and DragGesture the officially recommended approach for zoom + pan on watchOS? 2. Is there any public API that provides built-in Photos-style behavior, or is a custom SwiftUI implementation expected? 3. Are there best-practice patterns for smooth scaling, maintaining image bounds, and constrained panning? Thanks for any guidance

We use SwiftUI's .tabViewBottomAccessory in our iOS apps for displaying an Audio MiniPlayer View (like in the Apple Music App). TabView(selection: $viewModel.selectedTab) { // Tabs here } .tabViewBottomAccessory { if viewModel.showAudioMiniPlayer { MiniPlayerView() } } The Problem This code works perfectly on iOS 26.0. When viewModel.showAudioMiniPlayer is false, the accessory is completely hidden. However, on iOS 26.1 (23B5059e), when 'viewModel.showAudioMiniPlayer' becomes false, the MiniPlayerView disappears, but an empty container remains, leaving a blank space above the tab bar. Is this a known Bug in iOS 26.1 and are there any effective workarounds?

When I run the following code and change Is On, I get a problem with the layout of the Picker. There is no problem when using Text(), but when using only Image, it works fine on iOS but there is a problem on macOS. Tested on macOS 26.1, Xcode 26.1. import SwiftUI struct ContentView: View { @State var model = Model() var body: some View { Form { Picker(Category, selection: $model.category) { ForEach(Category.allCases) { item in Image(systemName: item.icon) .tag(item) } } .pickerStyle(.segmented) Toggle(Is On, isOn: $model.isOn) } .formStyle(.grouped) } } struct Model { var category: Category = .a var isOn: Bool = false } enum Category: Int, Identifiable, CaseIterable { case a, b, c var id: Int { rawValue } var icon: String { switch self { case .a: return a.circle.fill case .b: return b.circle.fill case .c: return c.circle.fill } } var name: String { switch self { case .a: return a case .b: return b case .c: return c } } } code-block
