I encountered the same situation, but the version is Xcode 27 Beta 6, and the device is iOS 17. The minimal reproducible code is as follows: import SwiftUI import WidgetKit @main struct Xcode27LACrashApp: App { @Environment(\.isActivityFullscreen) private var isActivityFullscreen var body: some Scene { WindowGroup { Text(isActivityFullscreen ? "fullscreen" : "not fullscreen") } } } Crash info: dyld[712]: Symbol not found: _$s7SwiftUI17EnvironmentValuesV9WidgetKitE20isActivityFullscreenSbvg Referenced from: <6C188284-51F7-38B5-833C-13FDC11E4C2C> /private/var/containers/Bundle/Application/71A82AE6-495A-45AA-B823-A2E2597D6F6E/Xcode27LACrash.app/Xcode27LACrash.debug.dylib Expected in: <064E500D-3AE0-34EC-9759-52B592E7B15A> /System/Library/Frameworks/WidgetKit.framework/WidgetKit FB24532892

Same here, I have tested different sound file formats, it won't work.

Until beta 4, there were two ways to get the real AlarmKit authorization state: First: authorizationUpdates for await state in AlarmManager.shared.authorizationUpdates { // this state is correct } Second: The requested result, but possibly with an alert let state = try await AlarmManager.shared.requestAuthorization()

This is not even a bug. The cornerConfiguration appeared in the WWDC sessions, but until now, it does not exist in UIKit. In Beta 2, we could use layer.cornerRadius to simulate its behavior, but in Beta 3 it doesn’t work anymore. It’s really annoying for developers who want to use this new feature, but Apple didn’t tell us this feature is just in the video.

Same here. After adding .glassEffect, the text on the button disappeared—it was expected to show white "Tap Me."

Same here, my simulator version is iOS 18.4

Hi everyone, I found it was due to the default wallpaper. Just change the wallpaper to any non-default one, and the customize button works again. Now I can continue adopting the widget tint mode.

There is still no good way to fix this. Simply add two spaces at the start and end of the string Text(" F ").

I found this API for iOS 17 if #available(iOS 17.0, *) { self.hoverStyle = .init(shape: .capsule) }

Do you mean how to trigger a gesture in the simulator? You can try holding down the Option key and then moving your cursor.

I found a workaround https://www.avanderlee.com/swiftui/variable-widgetbundle-configuration/ @main struct StockAnalyzerWidgets: WidgetBundle { @WidgetBundleBuilder var body: some Widget { widgets() } func widgets() -> some Widget { if #available(iOS 16.0, *) { return WidgetBundleBuilder.buildBlock(StockAnalyzerWatchlistWidgets(), StockAnalyzerSymbolWidgets()) } else { return StockAnalyzerWatchlistWidgets() } } } Any body using this in production environment?

Testing this control was exhausting because I couldn't predict the results. Combining it with the original UI was an even more complicated issue. I really wanted a permission control like Photo Library.

Same { "code": 500, "message": "internal-error", "reason": "There was a problem with your request.", "requestUuid": "f8bd710e-1f2a-xxxx-xxxx-xxxxxxx" }

May, 2022 For iOS SwiftUI Widget, I'm using App Group to share userDefaults between main app and widget, I saw same information like this, but only appear once, the second time widget retrieve info (via WidgetCenter.reloadTimelines) seems successful. Maybe we can define when read userDefaults failed, and treat this a Xcode log noise? [User Defaults] Couldn't read values in CFPrefsPlistSource<0x2824ee900> (Domain: xxx, User: kCFPreferencesAnyUser, ByHost: Yes, Container: (null), Contents Need Refresh: Yes): Using kCFPreferencesAnyUser with a container is only allowed for System Containers, detaching from cfprefsd
