There’s not nearly enough info there to determine what’s happening other than the fact something is accessing a null pointer.

Jenny Gore,

Please provide us with your full logs, there is not enough information to go on from here. Exception Type: EXC_CRASH (SIGABRT) implies that you’ve crashed because someone aborted the program.

How to get logs off of an iOS device:

Windows:

  • Select a uproject file (Optional)
  • Select the Advance Tools tab
  • Select Other Deployment Tools…

  • Select the IPA for the game you wish to get a log for
  • The documents directory data will then be copied to Engine/Binaries/DotNET/IOS/IOS_Backups or GameDir/IOS_Backups if a uproject was selected
  • The log can then be found at IOS_Backups/Game/Saved/Logs
