Since we used the UIPageViewController control, no matter which system the model of the phone, every version always happens the same crash。 We use UIPageViewController control style is "UIPageViewControllerTransitionStyleScroll" , flip back and forth through "setViewControllers:" to set.We suspect that the crash is caused by a problem with the UIPageViewController control itself.Has anyone encountered it, and how should you avoid it The crash log is as follows： Fatal Exception: NSInternalInconsistencyException 0 CoreFoundation 0x9cb4 __exceptionPreprocess 1 libobjc.A.dylib 0x183d0 objc_exception_throw 2 Foundation 0x4e156c _userInfoForFileAndLine 3 UIKitCore 0x7951c4 -[UIPageViewController queuingScrollView:didEndManualScroll:toRevealView:direction:animated:didFinish:didComplete:] 4 UIKitCore 0x79f1d8 -[_UIQueuingScrollView _notifyDelegateDidEndManualScroll:toRevealView:direction:animated:didFinish:didComplete:] 5 UIKitCore 0x7a0b3c -[_UITransitionState cleanupWithFinishedState:completedState:] 6 UIKitCore 0x79e2e0 -[_UIQueuingScrollView _cleanUpCompletionState:didFinish:didComplete:] 7 UIKitCore 0x7a0718 -[_UIQueuingScrollView _didEndScroll:] 8 UIKitCore 0x7a08b8 -[_UIQueuingScrollView _didEndManualScroll] 9 UIKitCore 0x79ce40 -[_UIQueuingScrollView _scrollViewDidEndDecelerating] 10 UIKitCore 0x290f44 -[UIScrollView _scrollViewDidEndDeceleratingForDelegate] 11 UIKitCore 0x290ea4 -[UIScrollView _stopScrollDecelerationNotify:] 12 UIKitCore 0xbb238 -[UIScrollView _smoothScrollSyncWithUpdateTime:] 13 UIKitCore 0xba960 -[UIScrollView _smoothScrollWithUpdateTime:] 14 UIKitCore 0x387c90 -[UIScrollView _smoothScrollDisplayLink:] 15 QuartzCore 0x2946c CA::Display::DisplayLink::dispatch_items(unsigned long long, unsigned long long, unsigned long long) 16 QuartzCore 0x146f28 CA::Display::DisplayLink::dispatch_deferred_display_links(unsigned int) 17 UIKitCore 0x64e4b0 _UIUpdateSequenceRun 18 UIKitCore 0xcb2c8c schedulerStepScheduledMainSection 19 UIKitCore 0xcb21e8 runloopSourceCallback 20 CoreFoundation 0xd3128 __CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE0_PERFORM_FUNCTION__ 21 CoreFoundation 0xdf7b4 __CFRunLoopDoSource0 22 CoreFoundation 0x645e8 __CFRunLoopDoSources0 23 CoreFoundation 0x7a0d4 __CFRunLoopRun 24 CoreFoundation 0x7f3ec CFRunLoopRunSpecific 25 GraphicsServices 0x135c GSEventRunModal 26 UIKitCore 0x39d6e8 -[UIApplication _run] 27 UIKitCore 0x39d34c UIApplicationMain 28 ZongHeng 0x3d6fe0 main + 20 (main.m:20) 29 ??? 0x1cfc06dec (缺少) apple crash log is： 2023-06-11_08-57-36.0180_+0800-5913f345621ee9343b650052710f4d0ecdabadc6.crash 2023-06-10_03-38-38.1645_+0800-e6b405cf6b7044d62e0c25ea5a86865b1c515206.crash 2023-06-09_19-57-04.0177_+0800-5a23d96f5b2749c82056a938177521fc91ce7e36.crash 2023-06-04_09-12-40.8371_+0800-cdb129f42a53197ab519e061063102834a17d430.crash 2023-06-03_16-14-29.8388_+0800-45901a35aa78ec311ffd21551599433eb848c815.crash 2023-02-18_23-55-21.2704_+0800-39473cb20287d9708946d0886e54b6de2b64bc05.crash 2023-02-04_09-55-54.1312_+0800-a0b645c34d2186354c91f18f8c1e4463b419ee17.crash 2022-12-13_05-32-52.7418_+0800-a9ba3c3e72257c6f3a2cf7811509b6e8daa836bc.crash 2022-12-09_03-40-26.5813_+0800-90bd72a94d87e907c8cc3d1096da45ed79cbfe46.crash

Later, I discovered that this problem occurred not only iOS16.1.0 and later. This problem does not occur to all users (approximately one in a thousand) I have tried several methods (such as using different versions of xcode build App), but still not solved... And all the people around me who use iPhone can’t reproduce this problem, which also makes testing difficult Here are the crash logs caught by firebase： ****crash：com.apple.network.connections EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x0000000000000036 Crashed: com.apple.network.connections 0 libxpc.dylib 0x16020 _xpc_dictionary_insert + 96 1 libxpc.dylib 0x17bcc _xpc_dictionary_copy_apply + 76 2 libxpc.dylib 0x1566c _xpc_dictionary_apply_node_f + 156 3 libxpc.dylib 0x148e8 _xpc_dictionary_copy + 88 4 Network 0x27c6c8 -[NWConcrete_nw_protocol_options initWithOptions:] + 184 5 Network 0x321094 __nw_protocol_stack_copy_block_invoke_2 + 64 6 Network 0x7018b4 nw_array_apply + 124 7 Network 0x320c20 nw_protocol_stack_copy + 308 8 Network 0x328164 -[NWConcrete_nw_parameters initWithParameters:stripConnected:shallowCopy:] + 592 9 Network 0x475994 nw_endpoint_resolver_create_child_parameters + 116 10 Network 0x474540 nw_endpoint_resolver_update + 5920 11 Network 0x47dfc0 __52-[NWConcrete_nw_endpoint_resolver startWithHandler:]_block_invoke_2 + 84 12 Network 0x1448e8 __nw_resolver_update_client_block_invoke + 88 13 libdispatch.dylib 0x24b4 _dispatch_call_block_and_release + 32 14 libdispatch.dylib 0x3fdc _dispatch_client_callout + 20 15 libdispatch.dylib 0xd620 _dispatch_workloop_invoke + 2076 16 libdispatch.dylib 0x16e10 _dispatch_workloop_worker_thread + 652 17 libsystem_pthread.dylib 0xdf8 _pthread_wqthread + 288 18 libsystem_pthread.dylib 0xb98 start_wqthread + 8 com.apple.main-thread 0 libsystem_kernel.dylib 0xb48 mach_msg2_trap + 8 1 libsystem_kernel.dylib 0x13008 mach_msg2_internal + 80 2 libsystem_kernel.dylib 0x13248 mach_msg_overwrite + 388 3 libsystem_kernel.dylib 0x108c mach_msg + 24 4 CoreFoundation 0x7aaf0 __CFRunLoopServiceMachPort + 160 5 CoreFoundation 0x7bd34 __CFRunLoopRun + 1232 6 CoreFoundation 0x80ed4 CFRunLoopRunSpecific + 612 7 GraphicsServices 0x1368 GSEventRunModal + 164 8 UIKitCore 0x3a23d0 -[UIApplication _run] + 888 9 UIKitCore 0x3a2034 UIApplicationMain + 340 10 wetalktalk 0x38b394 main + 14 (main.m:14) 11 ??? 0x1d6e34960 (缺少)
