I have a UIHostingController on which I have set: hostingController.sizingOptions = [.intrinsicContentSize] The size of my SwiftUI content changes with animation (I update a @Published property on an ObservableObject inside a withAnimation block). However, I notice that my hostingController.view just jumps to the new frame without animating the change. Question: how can I animate the frame changes in UIHostingController that are caused by sizingOptions = [.intrinsicContentSize]

Hi Community, I'm excited to share R Helper, a speech practice app I built with accessibility as the core focus from day one. App Store: https://apps.apple.com/app/speak-r-clearly/id6751442522 WHY I BUILT THIS I personally struggled with R sound pronunciation growing up. It affected my confidence in school and job interviews. That experience taught me how important accessible practice tools are. R Helper helps children and adults practice R sounds with full accessibility support. ACCESSIBILITY FEATURES IMPLEMENTED VoiceOver - complete navigation and feedback Voice Control - hands-free operation Dynamic Type - scales to large accessibility sizes Reduce Motion - respects user preference Dark Mode - user controllable High Contrast compatibility Differentiate Without Color THE CHALLENGE Most speech practice apps ignore accessibility. I wanted to change that and prove that specialized educational apps can be fully accessible. KEY FEATURES Works 100% offline, no internet needed Zero data collection, privacy first G

I have a text editor where I replace the selected text when a button is tapped. Most of the time it works, but sometimes the new text is inserted at the end of the text instead of at the selected position. Is this a bug? @Bindable var note: Richnote @State private var selection = AttributedTextSelection() var body: some View { VStack { TextEditor(text: $note.content, selection: $selection) Button(Replace text) { let textToInsert = A long text that makes me think lalala note.content.replaceSelection(&selection, withCharacters: textToInsert) }

I have an existing iOS app with MapKit. It always shows the current user location with UserAnnotation. But the same isn't true for macOS. I have this sample macOS application in SwiftUI. In the following, the current user location with a large blue dot appears only occasionally. It won't, 19 of 20 times. Why is that? I do have a location privacy key in Info.plist. And the Location checkbox is on under Signing & Capabilities. import SwiftUI import MapKit struct ContentView: View { @State private var markerItems: [MarkerItem] = [ MarkerItem(name: Farmers Market 1, lat: 35.681, lon: 139.691), MarkerItem(name: Farmers Market 2, lat: 35.685, lon: 139.695), MarkerItem(name: Farmers Market 3, lat: 35.689, lon: 139.699) ] @State private var position: MapCameraPosition = .automatic var body: some View { Map(position: $position) { UserAnnotation() ForEach(markerItems, id: .self) { item in Marker(item.name, coordinate: CLLocationCoordinate2D(latitude: item.lat, longitude: item.lon)) } } .mapControl

Hi, I am looking to display (in SwiftUI) the Tabview page dots like in the weather app in the toolbar, an important thing is I want to keep page controls by tapping and scrubbing. Actually, I want to do what's on Apple Design's Page Controls page; here's the link and a photo of what I'd like to do. Could you help me? https://developer.apple.com/design/human-interface-guidelines/page-controls

Views placed inside tabViewBottomAccessory that access @Environment values or contain @State properties experience unstable identity, as shown by Self._printChanges(). The identity changes on every structural update to the TabView, even though the view's actual identity should remain stable. This causes unnecessary view recreation and breaks SwiftUI's expected identity and lifecycle behavior. Environment Xcode Version 26.2 (17C52) iOS 26.2 simulator and device struct ContentView: View { @State var showMoreTabs = true struct DemoTab: View { var body: some View { Text(String(describing: type(of: self))) } } var body: some View { TabView { Tab(Home, systemImage: house) { DemoTab() } Tab(Alerts, systemImage: bell) { DemoTab() } if showMoreTabs { TabSection(Categories) { Tab(Climate, systemImage: fan) { DemoTab() } Tab(Lights, systemImage: lightbulb) { DemoTab() } } } Tab(Settings, systemImage: gear) { List { Toggle(Show more Tabs, isOn: $showMoreTabs) } } } .tabViewBottomAccessory { AccessoryView() } .ta

This extension View { public func renderSomething() async throws { let renderer = ImageRenderer(content: self) // renderer.colorMode = .linear renderer.render { size, context in print(size) // ... } // ... } } let view: some View = ... view.renderSomething() // → exception will cause the program to exit with EXC_BREAKPOINT deep inside SwiftUI. This worked with previous versions of Xcode, SwiftUI, and macOS. Xcode Version 26.2 (17C52), macOS Sequoia 15.7.3, using toolchain bundled with Xcode.

I am using swift-subprocess, and need to disable the SubprocessSpan trait because Xcode 26.2 does not ship with a bundled version libswiftCompatibilitySpan.dylib, causing everything to crash built with Xcode that happens to use Span. However, I cannot disable that trait by doing any of the following things: .package( url: https://github.com/swiftlang/swift-subprocess.git, branch: main, traits: [] ), .package( url: https://github.com/swiftlang/swift-subprocess.git, branch: main, traits: [.trait(name: SubprocessFoundation)] ), Note that SubprocessSpan is default trait in subprocess: // Enable SubprocessFoundation by default var defaultTraits: Set = [SubprocessFoundation] #if compiler(>=6.2) // Enable SubprocessSpan when Span is available [except it is not] defaultTraits.insert(SubprocessSpan) #endif The package still builds with the SubprocessSpan enabled. This is not an issue with the subprocess package. According to this, I should use swift build on the command line, yet this isn't -- as is upgrading to Ta

I am profiling a simple SwiftUI test app on my new iPhone through my new MacBook Pro and everything is version 26.2 (iOS, macOS, Xcode). I run Instruments with the SwiftUI template using all of the default settings and get absolutely zero data after interacting with the app for about 20 seconds. Using the Time Profiler template yields trace data. Trying the SwiftUI template again with the sample Landmarks app has the same issue as my app.
