Some users have reported that the app's widgets have disappeared after we updated to the latest Xcode for iOS 18 development. They are unable to find our app in the widget search, which prevents them from re-adding the widget. We were unable to reproduce this issue on our own devices during testing. Could this be a system bug? Have others encountered a similar issue?

i export apple SF as custom sf for test. code is simple: var body: some ControlWidgetConfiguration { StaticControlConfiguration( kind:"ControlWidgetConfiguration" ) { ControlWidgetButton(action: DynamicWidgetIntent()) { Text("test") Image("custom_like") } }.displayName("test") } as we can see, it can't show image in the preview. but it can show image in the Control widget center. am i do some thing wrong?

here is my case: i add the AppIntent to both your app and widget extension targets. the intent will run my app process when app is running. it works perfectly on iOS 17. but iOS 18, my app process never called. i download app's demo, https://developer.apple.com/documentation/widgetkit/emoji-rangers-supporting-live-activities-interactivity-and-animations it looks like the same issue. it runs well because even it runs in the widget extension target, it still can present expected UI. but in real case, we need to run the app process to do some work. by debugging, i found the app process never called（set breakpoint）. i add openAppWhenRun, it works well on iOS 18. but it will open the app when the widget is running. it is not what i want.

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

- (void)viewDidLoad {     [super viewDidLoad];     [self.navigationController.navigationBar setBackgroundImage:[self imageWithColor:[UIColor redColor]] forBarMetrics:UIBarMetricsDefault]; } - (UIImage *)imageWithColor:(UIColor *)color {     CGRect rect = CGRectMake(0.0f, 0.0f, 1.0f, 1.0f);     UIGraphicsBeginImageContext(rect.size);     CGContextRef context = UIGraphicsGetCurrentContext();     CGContextSetFillColorWithColor(context, [color CGColor]);     CGContextFillRect(context, rect);     UIImage *image = UIGraphicsGetImageFromCurrentImageContext();     UIGraphicsEndImageContext();     return image; } it works on iOS14, but on iOS15. it doesn't work. the color of navigationBar does't change

the xcode will freze for 3mins when hit a breakpoint. it report "Fetching variables on xxx'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.

Project Info:A music player iOS App with watchOS app embedded. Project Structure: app target: music intent extenstion: intent (for iOS platform) watchOS app target: watchKit watchOS extension: watchKit Extension iOS app use intent extension to support SiriKit with play media intent, it works very well. now i want to support Siri on watchOS app, but i don't know how. i have tried to add new watch extension target, but it doesn't work. i t keeps saying "my app doesn't support xxx instruction". Please share if I have missed to read through some documentation / reference that solves this problem.

Application Specific Information: *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Unsupported object <CPActionSheetTemplate: 0x2819a4480> <identifier: CD077C44-7F3F-46CC-B713-35A0259124EA, userInfo: (null), tabTitle: (null), tabImage: (null), showsTabBadge: 0> passed to presentTemplate:animated:completion:. Allowed classes: {( CPAlertTemplate, CPVoiceControlTemplate, CPGridTemplate, CPListTemplate, CPNowPlayingTemplate, CPTabBarTemplate )}' [[NMCarPlayEventManage shareManage].carplayInterfaceController dismissTemplateAnimated:NO]; [[NMCarPlayEventManage shareManage].carplayInterfaceController presentTemplate:sp animated:YES];

i init a CPAlertTemplate with a CPAlertAction, on iOS17, action can called by button click, but on iOS18, action can not be called by button click. so i can't dissmiss the alert by button click.

here's my case, i develop a control widget, user can push a controlwidget to play music without open the app. i bind a AudioPlaybackIntent to the widget. when user click the widget, the app will receive the intent and start to play music. it works perfect when app running in background or foreground. but when app not launched, the respond is too slow, it takes several seconds to start play music. is there any way to make the respond faster when app not launched? if i want to do something when app not launched, what should i do?

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.

If user use AirPods, and he change the name of AirPods to "xxxx", how to get the origin name of AirPods?
