SwiftUI List performance

Hey all, I found a weird behaviour with the searchable component. I created a custom bottom nav bar (because I have custom design in my app) to switch between screens. On one screen I display a List component with the searchable component. Whenever I enter the search screen the first time, the searchable component is displayed at the bottom. This is wrong. It should be displayed at the top under the navigationTitle. When I enter the screen a second time, everything is correct. This behaviour can be reproduced on all iOS 26 versions on the simulator and on a physical device with debug and release build. On iOS 18 everything works fine. Steps to reproduce: Cold start of the app Click on Search TabBarIcon (searchable wrong location) Click on Home TabBarIcon Click on Search TabBarIcon (searchable correct location) Simple code example: import SwiftUI struct ContentView: View { @State var selectedTab: Page = Page.main var body: some View { NavigationStack { ZStack { VStack { switch selectedTab { c

Original Problem We use codesign and notarytool in a scripted environment to build and distribute binaries daily. We also do manual builds by logging into the build server using SSH. This has been working for many years, but after updating to a new Developer ID Application certificate, codesign was failing with errSecInternalComponent and the console logs showed errSecInteractionNotAllowed. Summary of Resolution Attempting to fix the problem resulted in multiple copies of the same Certificate which were NOT shown by Keychain Access. I had to run security delete-identity multiple times to clear out the redundant Identities and then imported the certificate using the security CLI tool. Details I originally followed these instructions for requesting and installing a new certificate: https://developer.apple.com/help/account/certificates/create-developer-id-certificates/ Tip: Use the security tool intead These instructions fail to mention two critical points: 1) they assume the machine you generate the request on

Hi! I recently had an idea to build an iOS app that allows users to create a system-level block of specified web domains by curating a blacklist on their device. If the user, for instance, inputs *example.com to their list, their iPhone would be blocked from relaying that network traffic to their ISP/DNS, and hence return an error message (iPhone can't open the page because the address is invalid) instead of successfully fetching the response from example.com's servers. The overarching goal of this app would be to allow users to time-block their use of specified websites/apps and grant them greater agency over their technology consumption, and I thought that an app that blocks traffic at the network level, combined with the ability to control when to/not to allow access, would be a powerful alternative to the existing implementations out there that work more on the browser-level (eg. via Safari extension, which is isolated to the scope of user's Safari browser) or via Screen Time (which can be easy t

Hey! Wa are developing a VPN app for iOS and whenever we enable enforceRoutes we see 20% to 30% download and upload speed drop. Here are example results from our environment: | Upload | Download | ------------------------------------------ enforceRoutes off | 337.65 | 485.38 | ------------------------------------------ enforceRoutes on | 236.75 | 357.80 | ------------------------------------------ Is this behavior known and expected? Is there anything we can do to mitigate the effect of enforceRoutes in our application? Test were performed on iOS 26.2.1.

I see many developers struggling with ASO where AI written content does not deliver results, performance analysis is unclear, localization is ignored, App Store optimization is incomplete, and keywords are often poorly chosen. I am considering running two simple group sessions to share practical tips and show clear ways to improve ASO with real effort involved, and I would like feedback on this idea whether offered for a small fee or even for free.

Hi, I have systematic crashes when updating Xcode Cloud Workflows in Xcode, reproduced with Xcode 26.2 and 26.3 RC. Steps to reproduce: Go to the Report Navigator Tab Select Cloud Edit Workflow Perform a change Click Save Crash I did not see any recent issue in the forum. I have a crash dump, but it's too long to post here.

[Submitted as FB21958289] A minimal SwiftUI app logs framework warnings when a bottom bar Menu is used with the system search toolbar item. The most severe issue is logged as a console Fault (full logs below): Adding 'UIKitToolbar' as a subview of UIHostingController.view is not supported and may result in a broken view hierarchy. Add your view above UIHostingController.view in a common superview or insert it into your SwiftUI content in a UIViewRepresentable instead. This appears to be a framework-level SwiftUI/UIKit integration issue, not custom UIKit embedding in app code. The UI may still render, but the warnings indicate an internal hierarchy/layout conflict. This occurs in simulator and physical device. REPRO STEPS Create a new project then replace ContentView with the code below. Run the app. The view uses NavigationStack + .searchable + .toolbar with: ToolbarItem(placement: .bottomBar) containing a Menu DefaultToolbarItem(kind: .search, placement: .bottomBar) EXPECTED RESULT

Device: iPhone (real device) iOS: 17.x Permission: Granted Notifications are scheduled using UNCalendarNotificationTrigger. The function runs and prints SCHEDULING STARTED. However, notifications never appear at 8:00 AM, even the next day. Here is my DailyNotifications file code: import Foundation import UserNotifications enum DailyNotifications { // CHANGE THESE TWO FOR TESTING / PRODUCTION // For testing set to a few minutes ahead static let hour: Int = 8 static let minute: Int = 0 // For production use: // static let hour: Int = 9 // static let minute: Int = 0 static let daysToSchedule: Int = 30 private static let idPrefix = daily-thought- private static let categoryId = DAILY_THOUGHT // MARK: - Permission static func requestPermission(completion: @escaping (Bool) -> Void) { let center = UNUserNotificationCenter.current() center.requestAuthorization(options: [.alert, .sound]) { granted, _ in DispatchQueue.main.async { completion(granted) } } } // MARK: - Schedule static func scheduleNext30Days(isPro: Bo

Is it possible to drive NavigationSplitView navigation with a view in sidebar (left column) that is not a List? All examples that I have seen from this year only contain List in sidebar. I ask this because I would like to have a more complex layout in sidebar (or first view on iOS) that contains a mix of elements, some of them non-interactive and not targeting navigation. Here’s what I would like to do: import SwiftUI struct Thing: Identifiable, Hashable { let id: UUID let name: String } struct ContentView: View { let things: [Thing] @State private var selectedThingId: UUID? var body: some View { NavigationSplitView { ScrollView(.vertical) { VStack { ForEach(things) { thing in Button(Thing: (thing.name) ( selectedThingId == thing.id ? selected : )) { selectedThingId = thing.id } } SomeOtherViewHere() Button(Navigate to something else) { selectedThingId = someSpecificId } } } } detail: { // ZStack is workaround for known SDK bug ZStack { if let selectedThingId { Text(There is a thin

Since upgrading to a new Mac I have been unable to pair XCode to devices using the Devices and Simulators window. When I press the + button I get 'no devices found'. I have a second Mac which works as expected. When I try 'xcrun devicectl list devices' the phone I've connected shows up with limited information and is 'unavailable'. If I run 'sudo xcrun devicectl list devices' then I get a message telling me not to run xcrun as root but also the full information about the phone as expected, plus it shows the status as 'available (paired)'. So the device seems to be defined with root privileges but XCode is not. I am running XCode 26.2 but this issue has been around since 26.0. Any suggestions welcome.
