Hi there. I'm getting a weird crash that only happens on offline mode and the crash it self does not provide useful information in order to fix it . It appears that is crashing on the UIViewController.present it self. Also the viewdidload from the controller that I am trying to open is not being called , so it's not a problem with the target controller. Also I don't have any init(coder) for the target controller . Any help would be great What I get on the console is this : First throw call stack: (0x18d44186c 0x1a245cc50 0x18d33a4a4 0x196747f30 0x1966d0f3c 0x18fa06300 0x196747ee0 0x1967480f8 0x1966d0f3c
