I'm displaying a MKMapView in SwiftUI by wrapping it in the UIViewRepresentable protocol. I think the crash may have something to do with "Metal API Validation Enabled" I'm running Xcode Version 13.1 (13A1030d) My iPhone is iOS 15.1 When I run the app, the map displays and if I rotate my phone the Map rotates properly. BUT after two or three rotations the app crashes. The top of the stack trace says: queue = 'com.Metal.CompletionQueueDispatch', stop reason = EXC_BAD_ACCESS (code=1, address=0x10) The Error displayed is "Thread 12: EXC_BAD_ACCESS (code=1, address=0x10)" I've reduced the code to just a few lines shown below ContentView.swift: struct ContentView: View {     var body: some View {         MapView()     } } MapView.swift: struct MapView: UIViewRepresentable {     typealias UIViewType = MKMapView     // Required by UIViewRepresentable protocol     func makeUIView(context: Context) -> MKMapView {         return MKMapView()     }          // Required by UIViewRepresentable protocol     func updateUIView(_ mapView: MKMapView, context: Context) {         print("updateUIView() called")     } } After the Console output shown below is displayed I rotate the phone back and forth several times to get the map to rotate between portrait and landscape. After several rotations I get the crash. The Console Output before the crash is is shown below. 2021-12-07 15:24:00.879362-0700 UIViewRepresentableHelloWorld[26817:1293647] Metal API Validation Enabled updateUIView() called The Stack Trace is shown below: * thread #18, queue = 'com.Metal.CompletionQueueDispatch', stop reason = EXC_BAD_ACCESS (code=1, address=0x10)   * frame #0: 0x0000000197a3a014 libobjc.A.dylib`objc_msgSend + 20     frame #1: 0x00000001cc5809a4 MetalTools`-[MTLDebugCommandBuffer preCompletionHandlers] + 316     frame #2: 0x00000001cc536070 MetalTools`-[MTLToolsCommandBuffer invokeCompletedHandlers] + 36     frame #3: 0x000000019958efa0 Metal`MTLDispatchListApply + 44     frame #4: 0x000000019958f374 Metal`-[_MTLCommandBuffer didCompleteWithStartTime:endTime:error:] + 596     frame #5: 0x00000001cb3fe144 IOGPU`-[IOGPUMetalCommandBuffer didCompleteWithStartTime:endTime:error:] + 216     frame #6: 0x000000019958f04c Metal`-[_MTLCommandQueue commandBufferDidComplete:startTime:completionTime:error:] + 132     frame #7: 0x00000001cb3fdf04 IOGPU`__IOGPUNotificationQueueSetDispatchQueue_block_invoke + 148     frame #8: 0x000000010486a048 libdispatch.dylib`_dispatch_client_callout4 + 16     frame #9: 0x0000000104885364 libdispatch.dylib`_dispatch_mach_msg_invoke + 424     frame #10: 0x0000000104870ff0 libdispatch.dylib`_dispatch_lane_serial_drain + 332     frame #11: 0x0000000104886188 libdispatch.dylib`_dispatch_mach_invoke + 504     frame #12: 0x0000000104870ff0 libdispatch.dylib`_dispatch_lane_serial_drain + 332     frame #13: 0x0000000104871e08 libdispatch.dylib`_dispatch_lane_invoke + 484     frame #14: 0x0000000104870ff0 libdispatch.dylib`_dispatch_lane_serial_drain + 332     frame #15: 0x0000000104871dd4 libdispatch.dylib`_dispatch_lane_invoke + 432     frame #16: 0x000000010487d4e8 libdispatch.dylib`_dispatch_workloop_worker_thread + 852     frame #17: 0x00000001da86de84 libsystem_pthread.dylib`_pthread_wqthread + 284

I'm running Xcode v 13.2.1 in the iPhone 13 Pro Max simulator. I created a new SwiftUI Core Data project with Xcode and when I run it, it generates an Error/Warning. I have not changed any of the code that was generated. The name of the test app is "DELETE_ME_NOW_ALSO" The run-time error/warning says: 2022-01-17 15:19:20.498339-0700 DELETE_ME_NOW_ALSO[85036:7758906] [error] warning:  View context accessed for persistent container DELETE_ME_NOW_ALSO with no stores loaded Is there a way I can fix this error/warning? Is this a bug in Xcode? Thanks -Bill

In App Store Connect, it's showing that there were 6 units downloaded last week but Proceeds says $0. If 'Units are the number of apps downloaded, and the apps are $2 each, then how can the proceeds be $0? (These apps have been priced at $2 for months and these are the data for the past week.)
