Unexpected Widget Refresh When Pausing or Playing Music in iOS App
Widget abnormal refresh My app is a music application. When playing or pausing a song, the status is synchronized to NowPlaying, and the app itself supports widgets. During testing, I found that when pausing or playing music, the widget triggers a timeline refresh, which is completely unexpected. However, switching songs does not cause this. Looking at Apple’s logs: By default 21:27:08.094490+0800 mediaremoted Set: origin-iPhone-1280262988/client-com.company.musicdev-10059 (music)/player-MediaRemote-DefaultPlayer setting inferred playback state from to By default 21:27:08.094607+0800 mediaremoted [MRDNowPlayingPlayerClient] PlaybackState changed from Playing to Paused for origin-iPhone-1280262988/client-com.company.musicdev-10059 (music)/player-MediaRemote-DefaultPlayer By default 21:27:08.094713+0800 mediaremoted [MRDNowPlayingPlayerClient] isPlaying changed to false for origin-iPhone-1280262988/client-com.company.musicdev-10059 (music)/player-MediaRemote-DefaultPlayer By default 21:27:08.111861+0800 mediaremoted Posted Active Now Playing Notification kMRMediaRemoteNowPlayingApplicationPlaybackStateDidChangeNotification for path origin-iPhone-1280262988/client-com.company.musicdev-10059 (music)/player-MediaRemote-DefaultPlayer By default 21:27:08.115550+0800 mediaremoted Response: handlePlaybackQueueRequest<B0BDBB4E-C539-4D39-B51C-718115EBD7C4 assistantd-2659 /M/L/AF/R[0:1]> returned for origin-iPhone-1280262988/client-com.company.musicdev-10059 (music)/player-MediaRemote-DefaultPlayer in 0.0005 seconds By default 21:27:08.119344+0800 assistantd Response: playbackQueue<B0BDBB4E-C539-4D39-B51C-718115EBD7C4 assistantd-2659 /M/L/AF/R[0:1]> returned <> for origin-iPhone-1280262988/client-com.company.musicdev-10059 (music)/player-MediaRemote-DefaultPlayer in 0.0010 seconds By default 21:27:08.122322+0800 SpringBoard Response: playbackState<63A30582-E3C2-4F4D-AC57-8E5841FAD568> returned for origin-iPhone-1280262988/client-com.company.musicdev-10059 (music)/player-MediaRemote-DefaultPlayer in 0.0005 seconds By default 21:27:08.126132+0800 chronod Observed com.company.musicdev stopped running for exempt reason: nowPlaying - remainingReasons: None By default 21:27:08.126285+0800 chronod [com.company.musicdev::com.company.musicdev.musicdesktopwidget:VisionWidget_medium4158108784:systemMedium:3758765227620768254:338.00/158.00/21.60:(null)~(null)] on local marked as requiring reload By default 21:27:08.126455+0800 chronod [com.company.musicdev::com.company.musicdev.musicdesktopwidget:VisionWidget_medium4158108784:3758765227620768254] Reload with configuration [systemRequest(sessionEnded)-immediate-free-1] By default 21:27:08.126854+0800 mediaremoted Response: handlePlaybackQueueRequest<ACF764D9-05A6-41FF-8BB5-8CB81A8BC163 assistantd-2659 /M/L/AF/R[0:1]> returned for origin-iPhone-1280262988/client-com.company.musicdev-10059 (music)/player-MediaRemote-DefaultPlayer in 0.0008 seconds By default 21:27:08.127960+0800 assistantd Response: playbackQueue<ACF764D9-05A6-41FF-8BB5-8CB81A8BC163 assistantd-2659 /M/L/AF/R[0:1]> returned <> for origin-iPhone-1280262988/client-com.company.musicdev-10059 (music)/player-MediaRemote-DefaultPlayer in 0.0016 seconds By default 21:27:08.128091+0800 wifid Response: playbackState returned for origin-iPhone-1280262988/client-com.company.musicdev-10059 (music)/player-MediaRemote-DefaultPlayer in 0.0115 seconds When the music state changes, you can see the widget is triggered to refresh. I want to ask if this is the system’s mechanism? I checked my code and there is no operation to actively refresh the widget when pausing or playing. Can this situation be avoided?

iPhone14 Pro navigator originY strange number 53.667
iPhone 14 Pro: status bar height : 54 navigator bar originY : 53.667 is this a system bug? it happens on simulator and real device. this may cause some problems when I use the (navigator bar height + status bar height) to calculate the originY of the content view. for example, i set the content view's originY to 98(54 + 44), but the navigator bar's originY is 53.667, so the content view's originY needs to be 98.667. it will have a gap 0.333px between the navigator bar and the content view.

watchOS 26: Audio Playback Interrupted by Fitness Notifications Across Multiple Apps
After upgrading to watchOS 26, users report that when playing music on Apple Watch, if a fitness reminder is received, the music automatically pauses and users need to manually tap the play button to resume music playback. This phenomenon occurs with multiple music and podcast apps. This issue did not exist before the upgrade. We would like to know if this is an Apple bug or if there are any special development configurations needed?"

Xcode15 beat5 debug extramely slow
the xcode will freze for 3mins when hit a breakpoint. it report "Fetching variables on ***'s iPhone" it happens when hit a new breakpoint, and the xcode will freeze for 3mins, then it will be ok. anysolution? its wasting my time. the xcode continue print the log below: (arm64) /Users/xx/Desktop/patch/Project/Pods/TestSDK/vendor/xxx.framework/xxx(FPEncryptMsg.pb-c.o) 0x00000c22: unable to locate module needed for external types: /Users/packagedevice/Library/Developer/Xcode/DerivedData/ModuleCache.noindex/38MC9CUKFC6LS/Darwin-MI6WZSG1PNOM.pcm error: '/Users/packagedevice/Library/Developer/Xcode/DerivedData/ModuleCache.noindex/38MC9CUKFC6LS/Darwin-MI6WZSG1PNOM.pcm' does not exist Debugging will be degraded due to missing types. Rebuilding the project will regenerate the needed module files. Our project has many dependencies which are binary file. And these dependencies are build in the remote serve。Anyone has ideas about this
