Is there a supported way to schedule a Live Activity update on the device for a known future date, so the system applies it while the app is suspended? It should update on the Lock Screen when the phone is locked, and in the Dynamic Island when the user is in another app, ideally with an alert. Local notifications can be scheduled for an exact date, but I haven't found an equivalent for Live Activities. My use case is a rest timer in a workout app that keeps all data on the device, with no server. When a rest starts, the app knows when it ends, and at that moment the Live Activity should show the next set and the time since the rest ended. Today the app schedules a local notification for the alert and sets the Live Activity's stale date to the rest's end. That has some problems: The stale date is applied a minute or two late in my testing, so the Live Activity shows 0:00 after the notification has already arrived. Updating from the app only works while it's running, which in practice means during a workout mirrored from Apple Watch. Even then, an alert sent with the update while the phone was locked appeared about a minute late, so the Live Activity never alerts. Push updates need a server, which this app doesn't have by design. A scheduled Live Activity start (iOS 26) creates a second activity instead of updating the existing one. Am I missing an API or a pattern for this? I've filed FB25210471 asking for it in case there isn't one.

Hi, I have a workout app in the App Store which mirrors workout data between the phone and watch. Since iOS 26.x I've been having issues and received reports of the mirroring no longer working. Users in iOS 18 have no problems with this functionality. Bug description: A workout session is started from the phone app and starts mirroring to the watch companion device. The watch starts the workout session and then the mirroring session is disconnected / lost. Sending data to the companion device fails and ending the session on the phone doesn't end the session on the watch...essentially they become completely disconnected. Please note I am testing this on physical devices...not simulators. As a sanity check I've also tried the "Building a multidevice workout app" sample code and it has the same problem. To re-create on the sample app, I start a workout from the phone, the watch workout starts and then the mirroring session seems to disconnect and is unable to send data. This is the log from the "Building a multidevice workout app" sample code.

Hey there, New Xcoder here....in the editor there is a feature that highlights the starting / ending brace of a function. I find this extremely distracting and often lose the input caret position when using the Default (Dark) theme. Is there a way to modify the color or disable this feature? I couldn't find any answers when searching the internet brain hive. Using Xcode 15. Thanks for any tips!
