Hello! I wanted to bring up an issue I've encountered with .popover(isPresented:). It does not show up above a TabView on iOS 18. This issue occurs on an iPad or on an iPhone when using the .popover compact adaptation modifier. (Xcode 16 beta 6 + iOS 18 beta 7)

Hello, I noticed a small mistake in the Human Interface Guidelines (HIG). On the page HIG > Components > System Experiences > Widget > watchOS Widget Dimensions, scroll down to the bottom. In the "watchOS widget dimensions" section, the sizes in the table are in pixels (px), not points (pt) actually. However, the table header indicates the sizes should be in points (pt). Page link: https://developer.apple.com/design/human-interface-guidelines/widgets#watchOS-widget-dimensions For example, the widget size in the Smart Stack on a 49mm watch should be 192x81.5 pt (or 382x163 px), not 382x163 pt. This size can be verified with the information provided here: https://developer.apple.com/documentation/watchos-apps/supporting-multiple-watch-sizes/. https://developer.apple.com/documentation/watchkit/wkinterfacedevice/1620974-screenscale

Hello, I'd like to ask a very fundamental question about JSONEncoder: how to sort keys in a specific order when encoding a dictionary to JSON text? I know there is an option called JSONEncoder.OutputFormatting.sortedKeys, but it sorts the keys only in lexicographic order. I want to sort the keys using a different comparator, such as String.localizedStandardCompare(_:), which achieves the "Finder-like" order. The reason why I ask this question is because I have a localization tool that works with String Catalog (xcstrings file, which is a JSON), but every time my tool serializes an xcstrings file, it always messes up the keys in lexicographic order (I used JSONEncoder + .sortedKeys). Meanwhile, Xcode 16 always serializes the string keys into the "Finder-like" order. As a result, my tool always generates a huge diff when manipulating the xcstrings even when making only a small modification to it. So I am wondering how Xcode 16 implements the String Catalog tool to serialize the JSON in "Finder-like" order. It would be great if JSONEncoder could do that too. Or, maybe I can use another serialization method to implement this behavior?

Hello, I added a new iOS 26 app icon created with Icon Composer (named AppIcon) to my app, while keeping the previous version's icon (in Asset Catalog format, also named AppIcon). However, I found that once the bundle contains the Icon Composer icon file, the app cannot be submitted to App Store Connect. I received the following App Store Connect errors: ITMS-90022: Missing required icon file - The bundle does not contain an app icon for iPhone / iPod Touch of exactly '120x120' pixels, in .png format for iOS versions >= 10.0. To support older versions of iOS, the icon may be required in the bundle outside of an asset catalog. Make sure the Info.plist file includes appropriate entries referencing the file. See https://developer.apple.com/documentation/bundleresources/information_property_list/user_interface. ITMS-90023: Missing required icon file - The bundle does not contain an app icon for iPad of exactly '152x152' pixels, in .png format for iOS versions >= 10.0. To support older operating systems, the icon may be required in the bundle outside of an asset catalog. Make sure the Info.plist file includes appropriate entries referencing the file. See https://developer.apple.com/documentation/bundleresources/information_property_list/user_interface. ITMS-91111: Missing app icon - Include a large app icon as a 1024 by 1024 pixel PNG for the 'Any Appearance' image well in the asset catalog of apps built for iOS or iPadOS. Without this icon, apps can't be submitted for review. For details, visit: https://developer.apple.com/documentation/xcode/configuring-your-app-icon. Environment: Xcode 26 beta 3 FB: FB18987592

Hello, I noticed that the CADisplayLink seems to emit incorrect targetTimestamp and timestamp in the iOS 18 simulator. If you compute the actual duration of a frame, the duration is always a negative number. This only occurs in the iOS 18 simulator.

Hello, I'm using the custom symbol feature in the official SF Symbols app. I'm wondering if there is a way to sync my custom symbols across different devices? Since I have multiple Macs to work on, maybe iCloud?

Hello, I'm so glad that now you can scroll the list to top by tapping the tab bar ion on iOS 18. However, the current implementation on iOS 18 beta 8 has a little layout issue. import SwiftUI struct ContentView: View { var body: some View { TabView { Tab("Home", systemImage: "house") { NavigationStack { List { ForEach(0..<100) { i in Text("\(i)") } } .navigationTitle("Root") } } } } } #Preview { ContentView() } Tap the tab icon: Result:

Hello, Just noticed an issue with the .safeAreaInset() and .safeAreaPadding() modifiers. On iOS 18 beta 8, I'm unable to scroll the list or any other scrollable views within the safe area. This behavior is different compared to iOS 17/16. For example, adding a floating button using the .safeAreaInset() modifier: On iOS 18, the list cannot be scrolled or interacted within the bottom circled area.

Hi everyone, I've noticed that on iOS 26 beta 1 through beta 4, when using a List with the .plain style, the section header overlaps with the cell content below it, as there is no background for the header. This creates a poor visual experience. Additionally, when using NavigationSplitView on iPad, the second column's list always shows this issue. Is this an intentional design change, or just a temporary issue? I haven't found a good workaround so far. Thanks! FB19066489

Hi everyone! My Apple Watch app has relied for years on the WKApplication.scheduleBackgroundRefresh(...) method to keep the app updated in the background. The system would reliably trigger WKApplicationDelegate.handle(_:), where I would then schedule the next refresh task (usually 15 minutes later). As stated in the documentation, as long as there is a complication on the watch face, these background tasks should run at a relatively stable frequency. However, this approach seems to have stopped working on watchOS 26. I no longer receive any WKApplicationRefreshBackgroundTask at all. Has anyone else experienced this issue?

Hi everyone! I've encountered an issue when using Sheet + ScrollView on Mac Catalyst: the buttons in the toolbar appear with an abnormal gray color. import SwiftUI struct ContentView: View { var body: some View { VStack { } .sheet(isPresented: .constant(true)) { Sheet() } } } struct Sheet: View { var body: some View { NavigationStack { ScrollView { // <-- no issue if use List } .toolbar { Button(action: {}) { // <-- 👀 weird gray color Image(systemName: "checkmark") } } } } } Steps to Reproduce: On macOS 26.0 beta 9, use Xcode 26.0 beta 7 to create an iOS project and enable Mac Catalyst. Paste the code above. Select the Mac Catalyst scheme and run the project. The buttons in the toolbar show a strange gray appearance. If you change the ScrollView to a List in the code, the issue does not occur. FB20120285

I just discovered that I can no longer download any artifacts from Xcode Cloud, whether from newly built workflows or previous ones. When I try to download in Xcode, it crashes immediately. When downloading from App Store Connect, it redirects to an HTML page with the following content. {"message":"You are not authorized to access this team’s resources."} I've already tried re-logging into my Apple account. Is anyone else experiencing the same issue?

Recently, I’ve noticed that the Archive workflow on Xcode Cloud frequently fails randomly with the following error: ❌ Exporting for App Store Distribution failed. Please download the logs artifact for more information I’m not sure if this issue is on my side or if it’s related to Xcode Cloud itself. Has anyone encountered a similar problem?
