iOS 26 NavigationStack Title Rendering Issue
Is anyone else experiencing NavigationStack title disappearing in iOS 26? Hey everyone, I just updated to iOS 26 and I'm running into a really frustrating issue with my app. Wondering if anyone else is seeing this or if I'm missing something obvious. What's happening: My navigation titles are completely blank when the app first loads, but then magically appear when I scroll down. It's super weird and makes my app look broken at first glance. My setup: I'm using NavigationStack with some pretty standard stuff: Navigation title with .navigationTitle() A toolbar with a settings button ScrollView content with a gradient background Here's basically what I have: NavigationStack { ScrollView { VStack(spacing: 24) { // My app content here - cards, etc. ForEach(myItems) { item in // Content cards } } .padding() } .background( LinearGradient( gradient: Gradient(colors: [ Color.surfacePrimary, Color.surfacePrimary.opacity(0.95), Color.surfaceSecondary.opacity(0.3) ]), startPoint: .top, endPoint: .bottom ) ) .na

Reply to Novice SwiftUI developer can't make network call
I am not having trouble deciding what to do in my code if I get a non URL value in banjo. I'm using the same URL that I think I will always use, and that won't change. And that I'm checking is valid. That being the case I've tried pasting the code you gave me into xcode and it still won't build. Here's what I put in xcode let myString = https://www.alphavantage.co/query?function=TIME_SERIES_DAILY&symbol=AAPL&apikey= ********* if let banjo = URL(string: myString) { let Lulah = URLSession.shared.dataTask(with:banjo ) { myDatastring , response , error in} Lulah.resume() } else { myDatastring=nil url } I'm getting a build error on the line starting if let banjo. The build error is: Statements are not allowed at the top level and is tied to the first word, if. Thank you for your generous help.

Document title/proxy shifts left when adding an empty SwiftUI/AppKit toolbar - how to keep it centered?
I’m building a document-based macOS app using SwiftUI with an AppKit NSDocument. By default, when the window has no toolbar, the document title and proxy icon (with the edited state dot and standard saving controls) appear nicely centered in the title bar. However, as soon as I attach a toolbar - even an empty one - the document proxy moves to the leading edge of the title bar. Is there a way to keep the document proxy/title centered in a document-based SwiftUI app while also using a toolbar? Or is the left-alignment now the only supported behavior when a toolbar is present? Thanks in advance for any guidance.

Reply to Using MetricKit for Hangs on macOS
I have exactly the same problem, and would appreciate some guidance on whether hang diagnostics on macOS actually work. The same as the original poster above, the Simulate MetricKit Payload debug option works fine, and a crash is delivered immediately on restarting the app. No sign of any real hang reports though, even after deliberately causing hangs in the app. It’s my understanding that they should be delivered immediately, but even after waiting several days there’s still nothing. I’ve tried debug, release, and TestFlight builds. Any guidance as to what I could possibly be missing would be great! Thank you.

Associated Domain not working to Open App
Hello Having trouble getting associated domain to work in our project. It was working when we used Branch, but our company wants to host the domain ourselves. This is a multi-scheme project, using .xcconfig files to define the correct entitlement per Build. The relevant entitlement file has: com.apple.developer.associated-domains applinks:bm.ddcas.ai in the ....{other irrelevant test associated domains....} The project Team and App ID are taken from the Identifiers screen where the Identifier capabilities has 'associated domains' ticked on. I've also checked elsewhere on AppleDeveloper/Connect to be sure. When we used Branch with domain key app links: bmstores.app.link this worked fine. With https://bm.ddcas.ai (our own host) which is publicly available and has an aasa file in both the main directory and /.well-known, typing this in safari or anything just doesn't attempt to link to the App. The iPhone is in developer mode, and using the developer menu associated domains diagnostic tool, typing https

Issue after Build
I have a strange problem. My code works perfectly on my iPhone, i.e. on a real iPhone, but when I upload the build version to TestFlight, it no longer works. I use React Native. The issue is as follows: I have created a code for Grid View that runs automatically when another person joins the stream. It works locally without any problems, but unfortunately the public version does not work. What could be the reason for this?

Safari: Sticky element with bottom: 0 does not follow viewport when toolbar hides on scroll
Device: iPhone 15pro, ios26.0 (23A 341) IOS version: 26.0 (23A 341) When using position: sticky; bottom: 0, the div is expected to stick to the bottom of the viewport when the browser toolbar hides while scrolling. However, it stops at the height where the toolbar was, instead of moving down with the disappearing toolbar. In the image below, the red-bordered navigation shows the situation where it does not stick to the bottom. i

Reply to Xcode console print from autofill extension on MacOS
The more obscure your app or system extension, the more important it is to lean into the system log. Logging to stdout is fine for simple things, but once you start building a complex product you usually run into some case where you can’t see such output. Moreover, you can never see such output once you ship your product, which makes it much harder to debug problems that only show up in the field. So, my advice here is that you use this as an opportunity to switch over to the system log. It’s easy to use, has many great features, and your log entries will be visible regardless of the context. See Your Friend the System Log for lots of hints and tips on this front. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = eskimo + 1 + @ + apple.com

Reply to Allow "Browser" to find devices on local networks
I’d like to clarify your overall goal here. Are you planning to ship an app based on Chromium? Or are you building some sort of plug-in that you install within Chromium? This matters because… [quote='800879021, poluyanov, /thread/800879, /profile/poluyanov'] simply overwriting files in the app bundle [/quote] Right. That breaks the seal on the code signature, which causes problems for all privacy subsystems, which rely on the code signature to track the identity of your code, that is, to determine that version N+1 of your app is the ‘same code’ as version N. This is something we call out in TN3179 Understanding local network privacy: To ensure that local network privacy reliably tracks the identity of your macOS program, sign it with an Apple-issued code-signing identity. Most apps don’t suffer from this problem because, when Xcode rebuilds the app, it signs result. If you’ve selected an Apple-issued code-signing identity, the new app has the same designated requirement as the previous app, and thus

Reply to ITMS-90429: Invalid Swift Support – Swift libraries not at expected location in iOS app submission
@DTS Engineer What is your minimum deployment target set to? minimum deployment target set to 1 This is also an issue — that's a static library. .a files should never show up in a final app bundle, because their contents has been linked into some other binary during the build process. How can I integrate a static library (.a file) into an iOS app so that it does not appear in the final app bundle? Currently, I have defined a .podspec file and installed it via pod install.

Reply to ITMS-90429: Invalid Swift Support – Swift libraries not at expected location in iOS app submission
What is your minimum deployment target set to? All of these libswift* files should no longer be included. They were necessary for compatibility purposes on iOS versions prior to Swift being built into iOS directly, which is long past now. 14221248 09-16-2025 10:33 Payload/Runner.app/Frameworks/libAudioFeature.a This is also an issue — that's a static library. .a files should never show up in a final app bundle, because their contents has been linked into some other binary during the build process. — Ed Ford,  DTS Engineer

ScrollView + LazyVStack buggy animation. Fixable?
The below code will render a list of items and a button to shuffle them and change their height withAnimation. If you scroll down and shuffle it you will eventually see glitches in the animation, mostly consisting of ghost items animating on top of other items and disappearing. Does anyone know why this is happening, and how to stop it happening? The issue goes away entirely if I use a VStack, but using a VStack brings its own problems. import SwiftUI struct Item: Identifiable { let id = UUID() var height: CGFloat var label: String } struct ContentView: View { @State private var items: [Item] = (0..<30).map { i in Item(height: .random(in: 80...220), label: Row (i)) } var body: some View { NavigationStack { ScrollView { LazyVStack(spacing: 8) { ForEach(items) { item in Text(item.label) .frame(maxWidth: .infinity) .frame(height: item.height) .background(.gray.opacity(0.15)) .clipShape(RoundedRectangle(cornerRadius: 12)) .padding(.horizontal) } } .padding(.vertical) } .navigationTitle(LazyVStack Demo
