When I develop My WidgetKit Extension，I set some breakpoints for my code In the App Target And Extension Target ，It don't work，Who can help me solve this problem? Thank you!

I Down the Sample Code From Apple, The Example App For App Clips, Fruta. When I built It with the Xcode 12 Bate4 , Error was happened, Who can tell me Why? Some one else has built the App Fruta? The Error Code: #if APPCLIP Text("App Store Overlay") .hidden() .appStoreOverlay(isPresented: $presentingAppStoreOverlay) { 			 SKOverlay.AppClipConfiguration(position: .bottom) }  #endif The complete Code: var body: some View {         VStack(spacing: 0) {             Spacer()                          orderStatusCard                          Spacer()                          if presentingBottomBanner {                 bottomBanner             }                          #if APPCLIP             Text("App Store Overlay")                 .hidden()                 .appStoreOverlay(isPresented: $presentingAppStoreOverlay) {                     SKOverlay.AppClipConfiguration(position: .bottom)                 }             #endif         }         .onChange(of: model.hasAccount) { _ in             #if APPCLIP             if model.hasAccount {                 presentingAppStoreOverlay = true             }             #endif         }         .frame(maxWidth: .infinity, maxHeight: .infinity)         .background(             ZStack {                 if let order = model.order {                     order.smoothie.image                         .resizable()                         .aspectRatio(contentMode: .fill)                 } else {                     Color("order-placed-background")                 }                                  blurView                     .opacity(model.order!.isReady ? 0 : 1)             }             .edgesIgnoringSafeArea(.all)         )         .animation(.spring(response: 0.25, dampingFraction: 1), value: orderReady)         .animation(.spring(response: 0.25, dampingFraction: 1), value: model.hasAccount)         .onAppear {             DispatchQueue.main.asyncAfter(deadline: .now() + 4) {                 self.model.orderReadyForPickup()             }             #if APPCLIP             if model.hasAccount {                 presentingAppStoreOverlay = true             }             #endif         }     }

I output the package size report according to the document, and found that the package size increase appears on systems that do not support WidgetKit, such as iOS11. I think this is wrong. WidgetKit is only used in iOS14. Why should the package size of low-level systems become larger? 1、Report With WidgetKit Of low-level systems Supported variant descriptors: [device: iPhone10,2, os-version: 11.0], [device: iPhone10,3, os-version: 11.0], [device: iPhone10,5, os-version: 11.0], [device: iPhone9,4, os-version: 10.0], [device: iPhone9,2, os-version: 10.0], and [device: iPhone10,6, os-version: 11.0] App + On Demand Resources size: 76.4 MB compressed, 162.4 MB uncompressed App size: 76.4 MB compressed, 162.4 MB uncompressed On Demand Resources size: Zero KB compressed, Zero KB uncompressed 2、 Report Without WidgetKit Of low-level systems Supported variant descriptors: [device: iPhone10,3, os-version: 11.0], [device: iPhone9,2, os-version: 10.0], [device: iPhone10,2, os-version: 11.0], [device: iPhone10,5, os-version: 11.0], [device: iPhone10,6, os-version: 11.0], and [device: iPhone9,4, os-version: 10.0] App + On Demand Resources size: 75.8 MB compressed, 160.6 MB uncompressed App size: 75.8 MB compressed, 160.6 MB uncompressed On Demand Resources size: Zero KB compressed, Zero KB uncompressed Version 12.0 beta 6 (12A8189n)

In my Singleton Class，I used [UIImage imageNamed:] in the block of dispatch_once，it sometimes crash，I have thought many days，my image is stored in my App（Not in Assets，In My custom Resource File），it's unbelievable，who can tell me why? This is my Code     static dispatch_once_t onceToken;     static AClass *manager = nil;     dispatch_once(&onceToken, ^{         manager = [[AClass alloc] init];         dispatch_async(dispatch_get_global_queue(0, 0), ^{             NSMutableArray * imgDataList = [NSMutableArray array];             for (int i=0; i<=15; i++) {                 NSString *imageName=[NSString stringWithFormat:@"imageNamedxx_%d@2x.png",i];                 UIImage * img = [UIImage imageNamed:imageName]; if (img) { [imgDataList addObject:img]; }                             }             dispatch_async(dispatch_get_main_queue(), ^{                 manager.liveImgData = [imgDataList copy];             });         });     });     return manager; } 1 libobjc.A.dylib  objc_exception_throw  2 CoreFoundation  -[CFPrefsSearchListSource addManagedSourceForIdentifier:user:]  3 Foundation  -[NSAssertionHandler handleFailureInMethod:object:file:lineNumber:description:]  4 UIKitCore  -[_UIImageCGImageContent initWithCGImage:scale:]  5 UIKitCore  -[CUINamedImage(UIKitAdditions) UIImageWithAsset:configuration:flippedHorizontally:optionalVectorImage:]  6 UIKitCore  -[UIImageAsset imageWithConfiguration:]  7 UIKitCore  -[_UIPathLazyImageAsset imageWithConfiguration:]  8 UIKitCore  +[UIImage imageNamed:inBundle:withConfiguration:] myApp AClass - 第 42 行（[UIImage imageNamed:]） __34+[AClass shareInstance]_block_invoke_2 + 42

AnyOne Can tell me what's different about MXMemoryMetric and phys_footprint? Which is the really one dicide the app should be killed by OOM?

There Many Crash Report Like this, But no any code about my business can tell me why, so I think this is a system bug, Who can tell me why and how to avoid it?
