Reply to Widget with Core Data guidance
Not sure if I completely understand what you are trying to achieve, but an interactive widget can include a button or toggle, which, when tapped, can perform a task like retrieving data from your Core Data store in a shared App Group container, and doing calculation. This is detailed in Adding interactivity to widgets and Live Activities. The built-in Clock widget in iOS provides a configuration UI that allows selecting a city from a long list. Does it fit your use case? If a configureable widget doesn't fit, providing a button in your widget for users to tap and launch your app to do the configuration may be a choice?

Core Spotlight Semantic Search - still non-functional for 1+ year after WWDC24?
After more than a year since the announcement, I'm still unable to get this feature working properly and wondering if there are known issues or missing implementation details. Current Setup: Device: iPhone 16 Pro Max iOS: 26 beta 3 Development: Tested on both Xcode 16 and Xcode 26 Implementation: Following the official documentation examples The Problem: Semantic search simply doesn't work. Lexical search functions normally, but enabling semantic search produces identical results to having it disabled. It's as if the feature isn't actually processing. Error Output (Xcode 26): [QPNLU][qid=5] Error Domain=com.apple.SpotlightEmbedding.EmbeddingModelError Code=-8007 Text embedding generation timeout (timeout=100ms) [CSUserQuery][qid=5] got a nil / empty embedding data dictionary [CSUserQuery][qid=5] semanticQuery failed to generate, using (false) In Xcode 16, there are no error messages at all - the semantic search just silently fails. Missing Resources: The sample application mentioned during the WWDC24

Reply to What iPhone and iPad models under iOS 26 support SpeechTranscriber
But you publish iPhone and iPad list that support iOS 26. To plan an App that will work with SpeechTranscriber we definitely must have some information about the hardware that supports it. For example if SpeechTranscriber does not work on any iPhone and iPad it is not any sense to make App for using this Api. Also this Api does not work in Simulator, so the developer must buy the device that support this Api.

.hidden not working when making UIBarButtonItem visibles on iOS 26
Hi, I have a UIToolbar at the bottom of my screen. The UIToolbar is made of UIBarButtonItems. At some point, I change the status of some buttons to hidden: button.isHidden = true This works: the buttons become invisible. At a later point in the process, I turn the buttons visible again: button.isHidden = false This did work on iOS 18, and does not work with the iOS 26 SDK: the buttons remain hidden, even though the property has been set to false. Am I doing it wrong? Is there anything I can do to fix this?

Reply to .hidden not working when making UIBarButtonItem visibles on iOS 26
In case other developers encounter the same issue, I found out by accident that I can force the toolbar to check the status of its buttons by adding an extra button, then removing it: if #available(iOS 26, *) { self.editorToolbar.items?.append(UIBarButtonItem(title: Hi, style: .plain, target: self, action: nil)) self.editorToolbar.items?.removeLast() } With this change, the buttons that were hidden become apparent again. Now I have the issue that the longPressGesture is not called on the buttons that were temporarily hidden...

xcodebuild -exportLocalizations Fails Due to Cross-Platform Dependencies
I'm working on a large multi-platform iOS project (iOS, iPadOS, watchOS, tvOS, visionOS) and have successfully migrated from legacy .strings files to modern String Catalogs (.xcstrings). However, I'm unable to export localizations using xcodebuild -exportLocalizations due to cross-platform framework dependency issues. (Note: I did have AI help me write this question, so apologies in advance for any errors) Project Structure Main iOS/iPad app with multiple extensions watchOS companion app tvOS app visionOS app 49 .xcstrings files successfully migrated across all targets Uses Swift Package Manager for modularization The Problem When attempting to export localizations using xcodebuild -exportLocalizations, the build fails because it tries to build all targets across all platforms, including watchOS targets that depend on third-party xcframeworks that don't include watchOS slices: xcodebuild -exportLocalizations -project MyProject.xcodeproj -scheme MyApp -localizationPath ./export -

Reply to Example of DNS Proxy Provider Network Extension
Actually, slight Edit. We are ok with going in to iOS Settings once when it's first loaded to switch to our DoT settings, but after that we'd like to be able to turn it on and off from within the app and haven't yet figured out how to do that without access to the isEnabled property on NEDNSSettingsManager. We can remove it altogether. But then we have to go back into Settings when we re-load it to enable it, which we are trying to avoid (and other apps seem to be able to disable and enable from within the app).

Game Center Access Point does not appear on iOS 26 (Simulator)
Attempting to bring up the access point yields the following error log: [GameCenterOverlayService] Failed to create GameOverlayUI Dashboard Remote Proxy [GameCenterOverlayService] Could not create endpoint for service name: com.apple.GameOverlayUI.dashboard-service [GameCenterOverlayService] Failed to create GameOverlayUI Dashboard Remote Proxy [GameCenterOverlayService] Could not create endpoint for service name: com.apple.GameOverlayUI.dashboard-service [GameCenterOverlayService] Failed to create GameOverlayUI Dashboard Remote Proxy [GameCenterOverlayService] Failed to create GameOverlayUI Dashboard Remote Proxy The same code (which is a single line setting 'active' to true) works on physical devices and on the simulator in iOS 18.6 I haven't been able to find any mention of this issue online. Any suggestions or help greatly appreciated.

Reply to App Crashes in UICollectionView.m:3974
Thank you for your post. Could you please provide more information? Are you unable to locate a crash file on your device using the sysdiagnose. Additionally, the post does not include the version of iOS or any other relevant details that would allow me to determine the cause of the crash. Could you utilize Xcode to debug the application and reproduce the crash? Providing additional information would be beneficial in guiding you to obtain the crash file. Kindly submit a comprehensive crash report, adhering to the guidelines outlined in Posting a Crash Report. Hope this helps: https://developer.apple.com/forums/thread/688669 Looking forward to figure it out. Albert Pascual

Questions about using App Extension communication with host apps on iOS 26 (Xcode 26)
Hello, I have a few questions regarding the documentation here: Can this method described in the article be built with Xcode 26 and run on iOS 26? Or is it restricted to run only on iOS 26, since AppExtensionPoint appears to be available starting from iOS 26? Does this approach allow two apps under the same Team ID to communicate with each other? Does this approach also allow two apps under different Team IDs to communicate with each other? Is it mandatory to implement EXAppExtensionBrowserViewController and obtain user consent before using this method to exchange information? In our implementation, we followed the documentation. Inside EXAppExtensionBrowserViewController, we were able to see the Generic Extension from another app and enabled the permission. However, we still get the following error: Failed to connect: Error Domain=NABUExtensionConnector Code=1 No matching extension found UserInfo={NSLocalizedDescription=No matching extension found} Could someone clarify whether thi

Notifications False Sucecss Delivery
We operate a social network application, SportsYou with over 3 million monthly active users and are experiencing significant issues with push notification delivery through APNs. We have a large number of users reporting they are not receiving push notifications. Our infrastructure uses AWS SNS integrated with APNs to deliver notifications. However, AWS CloudWatch consistently reports successful delivery (Success response), even though users confirm they never received the notifications. Because we receive success responses from AWS SNS, our system does not attempt to recreate or refresh the device endpoints. This leaves us unable to detect or recover from these delivery failures automatically. This issue is widespread and inconsistent. It affects users across multiple variables including different iOS versions, different device models, and different versions of our application. We cannot identify a clear pattern that would help us isolate the root cause. With millions of active users, even a small pe

Mac OS Tahoe 26.0 (25A354) Sound Glitches When opening the simulator app
Hey there, I just upgraded to Mac OS Tahoe ,son an apple MacBook Pro 2019 16inch. am using IntellijIDEA and Flutter to develop a mobile app which I test on the simulator app running iOS 18.4 . the issue: when I start the simulator app. ( while in the loading phase and in the operation phase as well ), the audio from an already open YouTube tab on safari (this happens on chrome browser as well). the sound glitches and becomes Noise. a fix I found online is to kill the audio deamon on Mac OS, This works using the command: sudo killall coreaudiod this kills the audio process, (while the emulator is operational), then the macOS restarts the audio deamon then the audio works fine alongside with the simulator being open. I just want to ask is there a permanent fix for this? is Apple working on a fix for this in the upcoming update?

Reply to Questions about using App Extension communication with host apps on iOS 26 (Xcode 26)
[quote='861033022, DTS Engineer, /thread/802846?answerId=861033022#861033022'] I’m still researching the exact details of those limitations [/quote] Hey hey, that went quicker than I expected. As things currently stand on iOS 26, an app can only host extensions that it contains. Needless to say, this significantly undermines the utility of the ExtensionKit. While it’s possible that you might find a creative use for it, there’s one specific situation where it’s super useful, namely, using an extension to host code that is either unreliable or deals with untrusted data. For more on that last point, see Creating enhanced security helper extensions. There’s obviously a lot of demand from third-party developers to broaden the scope of ExtensionKit on iOS. If you have a specific use case in mind, feel free to file an enhancement request with the details. That’s particularly important if your use case is limited in some way. As I mentioned above, we already have an ER for the sort of general suppor
