ios - SceneKit application dumps when swiping up from lower edge -

i'm creating application using new scenekit framework ios , i'm wondering weird bug. because didn't know if causing bug, created new project , still there. occurs when ipad (i'm using physical testing device) in landscape right mode when swiping "home-button-sided" border center of screen. compiler gives next information:

2014-06-20 18:22:12.066 game[727:60518] * terminating app due uncaught exception 'nsinvalidargumentexception', reason: '* -[__nssetm addobject:]: object cannot nil' * first throw phone call stack: (0x2afea2bf 0x37ee0d2f 0x2af0aee5 0x2e846c97 0x2e5cd22b 0x2afb1e47 0x2afb1257 0x2afaf8bd 0x2aefcfb1 0x2aefcdc3 0x320782c9 0x2e62ca1d 0x7fd25 0x38461aaf) libc++abi.dylib: terminating uncaught exception of type nsexception
