EXC_BAD_ACCESS (SIGSEGV) crash
Hi Friends. With the new iOS 16.2 update in my iPad device, my app started failing. It works in simulator but fails in real device. Below are the device logs : Tried searching various forums, tried address santizer and zombies but couldn't find useful. I am a bit newbie to Xcode so not so knowledge on how to debug. Can anyone help me on how can I determine place of error and possible fix from the log. thanks in advance Exception Type:    Exception Subtype: KERN_INVALID_ADDRESS at 0x0000000000000020 Exception Codes: 0x0000000000000001, 0x0000000000000020 VM Region Info: 0x20 is not in any region.  Bytes before following region: 68719476704       REGION TYPE                 START - END      [ VSIZE] PRT/MAX SHRMOD  REGION DETAIL       UNUSED SPACE AT START --->         commpage (reserved)     1000000000-7000000000 [384.0G] ---/--- SM=NUL  ...(unallocated) Termination Reason: SIGNAL 11 Segmentation fault: 11 Terminating Process: exc handler [394] Triggered by Thread:  0 Kernel Triage: VM - pmap_enter retried due to resource shortage VM - pmap_enter retried due to resource shortage VM - pmap_enter retried due to resource shortage Thread 0 name:   Dispatch queue: com.apple.main-thread Thread 0 Crashed: 0   libobjc.A.dylib                      0x1c7bdae5c objc_retain + 16 1   UIKitCore                            0x1d0c2f000 -[_UIButtonBarItemLayout _updateItemViewSizing] + 116 2   UIKitCore                            0x1d0c30970 -[_UIButtonBarItemLayout _updateItemView] + 364 3   UIKitCore                            0x1d108c964 -[_UIButtonBarItemLayout minimumLayoutWidthGivenMinimumSpaceWidth:] + 28 4   UIKitCore                            0x1d108d074 -[_UIButtonBarItemGroupLayout recalculateLayoutWidthsGivenItemSpaceWidth:] + 296 5   UIKitCore                            0x1d1084ddc -[_UIButtonBar _widthInfoForLayout:] + 200 6   UIKitCore                            0x1d10ca6b4 -[_UINavigationBarContentViewLayout _buttonBarLayoutInfo] + 336 7   UIKitCore                            0x1d10caa14 -[_UINavigationBarContentViewLayout layoutSubviews] + 64 8   UIKitCore                            0x1d0a84400 -[_UINavigationBarContentView layoutSubviews] + 172 9   UIKitCore                            0x1d0a81860 -[UIView(CALayerDelegate) layoutSublayersOfLayer:] + 1980 10  QuartzCore                           0x1cff54b0c CA::Layer::layout_if_needed(CA::Transaction*) + 500 11  UIKitCore                            0x1d0b4ee80 -[UIView(Hierarchy) layoutBelowIfNeeded] + 292 12  UIKitCore                            0x1d0c23680 -[UINavigationController _positionNavigationBarHidden:edge:initialOffset:] + 580 13  UIKitCore                            0x1d0c233c0 -[UINavigationController _positionNavigationBarHidden:edge:] + 268 14  UIKitCore                            0x1d0c231c4 -[UINavigationController __viewWillLayoutSubviews] + 148 15  UIKitCore                            0x1d0c230f4 -[UILayoutContainerView layoutSubviews] + 172 16  UIKitCore                            0x1d0a81860 -[UIView(CALayerDelegate) layoutSublayersOfLayer:] + 1980 17  QuartzCore                           0x1cff54b0c CA::Layer::layout_if_needed(CA::Transaction*) + 500 18  QuartzCore                           0x1cff681c0 CA::Layer::layout_and_display_if_needed(CA::Transaction*) + 148 19  QuartzCore                           0x1cff79534 CA::Context::commit_transaction(CA::Transaction*, double, double*) + 444 20  QuartzCore                           0x1cffae930 CA::Transaction::commit() + 652 21  UIKitCore                            0x1d0f10304 __34-[UIApplication _firstCommitBlock]_block_invoke_2 + 36 22  CoreFoundation                       0x1ce8eb524 CFRUNLOOP_IS_CALLING_OUT_TO_A_BLOCK + 28 23  CoreFoundation                       0x1ce953d7c __CFRunLoopDoBlocks + 368 24  CoreFoundation                       0x1ce923ba0 __CFRunLoopRun + 856 25  CoreFoundation                       0x1ce928ec0 CFRunLoopRunSpecific + 612 26  GraphicsServices                     0x2080d3368 GSEventRunModal + 164 27  UIKitCore                            0x1d0e1e86c -[UIApplication _run] + 888 28  UIKitCore                            0x1d0e1e4d0 UIApplicationMain + 340 29  RD Vurdering TEST                    0x100486f94 main + 28564 (main.m:9) 30  dyld                                 0x1ed13a960 start + 2528
