SwiftUI List performance

I have this sample code import SwiftUI struct ContentView: View { var body: some View { ParentView() } } struct ParentView: View { @State var id = 0 var body: some View { VStack { Button { id+=1 } label: { Text(update id by 1) } TestView(id: id) } } } struct TestView: View { var sequence = DoubleGenerator() let id: Int var body: some View { VStack { Button { sequence.next() } label: { Text(print next number).background(content: { Color.green }) } Text(current id is (id)) }.task { for await number in sequence.stream { print(next number is (number)) } } } } final class DoubleGenerator { private var current = 1 private let continuation: AsyncStream.Continuation let stream: AsyncStream init() { var cont: AsyncStream.Continuation! self.stream = AsyncStream { cont = $0 } self.continuation = cont } func next() { guard current >= 0 else { continuation.finish() return } continuation.yield(current) current &*= 2 } } the print statement is only ever executed if I don't click on the update id by 1 button.

Many Apple users own both Bluetooth earphones (AirPods) and traditional wired earphones. While Bluetooth audio provides freedom of movement, some users still prefer wired earphones for comfort, sound profile, or personal preference. However, plugging wired earphones directly into an iPhone can feel restrictive and inconvenient during daily use. This proposal suggests a hybrid audio approach where wired earphones can be connected to a Bluetooth-enabled AirPods charging case (or a similar Apple-designed module), allowing users to enjoy wired earphones without a physical connection to the iPhone. #Problem Statement *Wired earphones offer consistent audio quality and zero latency *Bluetooth earphones provide freedom from cables *Users must currently choose one or the other *Plugging wired earphones into an iPhone limits movement and can feel intrusive in daily scenarios (walking, commuting, working) There is no native Apple solution that allows wired earphones to function wirelessly while maintaining Apple’s audi

Hi! I have a bigger Xcode project that has multiple targets: the main app (MainApp) helper command line tool (HelperTool) The project also lists multiple package dependencies via SwiftPM and these dependencies have dependencies between themselves. One of such packages produces a dynamic library MyFramework which is a dependency for both the main app and the HelperTool which has it listed under Build Phases > Dependencies as well as under Link with Frameworks. This builds just fine, but the issue somes when I want to add another target called AdditionalHelperTool which it has pretty much the same dependencies as HelperTool. When I add this second target, I start running into issues like the following: Multiple commands produce '[...]/Build/Products/Debug/Frameworks/MyFramework.framework/Versions/A' Target 'HelperTool' (project 'MyApp') has copy command from '[...]/Build/Products/Debug/PackageFrameworks/MyFramework.framework' to '[...]/Build/Products/Debug/Frameworks/MyFramework.framework'

Hi all, I’m working on the alternative marketplace app and using MarketplaceKit and ActionButton. On the main page, users see a list of items, each with an ActionButton. I’m experiencing significant UI hangs when this page loads. What I’ve Observed: Instruments (Hangs and SwiftUI profilers) show that the hangs occur when ActionButton instances are rendered. Creating or updating ActionButton properties triggers synchronous XPC communication with the managedappdistributiond process on the main thread. Each XPC call takes about 2-3 ms, but with many ActionButtons, the cumulative delay is noticeable and impacts the user experience. I have tested on iOS 18.7 and 26.1, using Xcode 26.2. But in general, the issue is not specific to a device or iOS version. The problem occurs in both Debug and Release builds. Hangs can be severe depending on the number of items in a section, generally between 200-600 ms, resulting in noticeable lag and a poor user experience. I haven’t found much documentation on th

I failed to resize the icon image from instances of NSRunningApplication. I can only get 32×32 while I'm expecting 16×16. I felt it unintuitive in first minutes… Then I figured out that macOS menu seems not allowing many UI customizations (for stability?), especially in SwiftUI. What would be my best solution in SwiftUI? Must I write some boilerplate SwiftUI-AppKit bridging?
