CoreGraphics: CGPDFPageCopyRootTaggedNode
My app uses PDFKit, but I don't know how to solve this bug at all. Under the same IOS system and device model, some users' devices may experience crashes, while our own devices are functioning normally. The following is the stack information for crashing: 0 libsystem_platform.dylib__os_unfair_lock_recursive_abort + 36 1 libsystem_platform.dylib__os_unfair_lock_lock_slow + 308 2 CoreGraphics_CGPDFPageCopyRootTaggedNode + 56 3 PDFKit-[PDFPageViewAccessibility accessibilityElements] + 76 4 UIAccessibility-[NSObject(AXPrivCategory) _accessibilityElements] + 56 5 UIAccessibility-[NSObjectAccessibility accessibilityElementCount] + 68 6 UIAccessibility-[NSObject(AXPrivCategory) _accessibilityHasOrderedChildren] + 44 7 UIAccessibility-[NSObject(AXPrivCategory) _accessibilityFrameForSorting] + 216 8 UIAccessibility-[NSObject _accessibilityCompareGeometry:] + 116 9 UIAccessibility-[NSObject(AXPrivCategory) accessibilityCompareGeometry:] + 52 10 CoreFoundation___CFSimpleMergeSort + 100 11 CoreFoundation___CFSimpleMergeSort + 248 12 CoreFoundation_CFSortIndexes + 260 13 CoreFoundation-[NSArray sortedArrayFromRange:options:usingComparator:] + 732 14 CoreFoundation-[NSMutableArray sortedArrayFromRange:options:usingComparator:] + 60 15 CoreFoundation-[NSArray sortedArrayUsingSelector:] + 168 16 UIAccessibility___57-[NSObject(AXPrivCategory) _accessibilityFindDescendant:]_block_invoke + 268 17 UIAccessibility___96-[NSObject(AXPrivCategory) _accessibilityEnumerateAXDescendants:passingTest:byYieldingElements:]_block_invoke + 140 18 UIAccessibility-[NSObject _accessibilityEnumerateAXDescendants:passingTest:byYieldingElements:] + 244 19 UIAccessibility-[NSObject _accessibilityFindFirstAXDescendantPassingTest:byYieldingElements:] + 272 20 UIAccessibility-[NSObject(AXPrivCategory) _accessibilityFindDescendant:] + 100 21 UIAccessibility__axuiElementForNotificationData + 276 22 UIAccessibility__massageAssociatedElementBeforePost + 36 23 UIAccessibility__UIAXBroadcastMainThread + 292 24 libdispatch.dylib__dispatch_call_block_and_release + 32 25 libdispatch.dylib__dispatch_client_callout + 20 26 libdispatch.dylib__dispatch_main_queue_drain + 980 27 libdispatch.dylib__dispatch_main_queue_callback_4CF + 44 28 CoreFoundation___CFRUNLOOP_IS_SERVICING_THE_MAIN_DISPATCH_QUEUE__ + 16 29 CoreFoundation___CFRunLoopRun + 1996 30 CoreFoundation_CFRunLoopRunSpecific + 572 31 GraphicsServices_GSEventRunModal + 164 32 UIKitCore-[UIApplication _run] + 816 33 UIKitCore_UIApplicationMain + 340 34 SwiftUIclosure #1 (Swift.UnsafeMutablePointer<Swift.UnsafeMutablePointer<Swift.Int8>?>) -> Swift.Never in SwiftUI.(KitRendererCommon in _ACC2C5639A7D76F611E170E831FCA491)(Swift.AnyObject.Type) -> Swift.Never + 168 35 SwiftUI SwiftUI.runApp(A) -> Swift.Never + 100 36 SwiftUI static (extension in SwiftUI):SwiftUI.App.main() -> () + 180
