Help with crash report

I recently received this crash report from a user using El Capitan, and my development environment is El Capitan as well.

I am trying to understand what is causing the crash, but having difficulty reading the crash report.

Compared to usual, it doesn't seem to specifically say what the matter is.

Help would be much appreciated.

I believe "EXC_CORPSE_NOTIFY" is what you get in Swift when you reference an "unowned" property that's no longer a valid pointer. The backtrace seems to say that your app received an AppleEvent and it's trying to open a window as a result, and something referenced by the window does't exist any more.


This is most likely a memory management error in your code.

If you can convince Xcode to symbolicate that crash report, then these lines

will point to the exact file and line numbers in your code where the crash occurred.

Thank you junkpile.

I've looked here for directions on how to symbolicate crash reports,

and am awaiting related files such as the DSYM file, CoreData, etc. from the user.


The wierd thing is that I have the same environment as the user, but I don't seem to have any issues starting the app.

Thank you QuinceyMorris.


Simply put, I have two windows I have to show depending on a certain condition.

I know from the user that 'something()' is false.


The storyboard has a NSWindowController with a Storyboard ID of "MainWindowController", and has it's window content set to a NSSplitViewController.

Could it be something in that NSSplitViewController?


class AppDelegate: NSObject, NSApplicationDelegate {

    var mainWindowController: NSWindowController?
    var altWindowController: NSWindowController?


    func applicationDidFinishLaunching(aNotification: NSNotification) {
        self.mainWindowController = NSStoryboard(name: "Main", bundle: NSBundle.mainBundle())
.instantiateControllerWithIdentifier("MainWindowController") as! NSWindowController

        if something() {
           // Set altWindowController and show
        } else {
            showMainWindow()
        }
    }

    func showMainWindow() {
        self.mainWindowController.window?.setFrame(NSMakeRect(self.mainWindowController.window!.frame.origin.x, self.mainWindowController.window!.frame.origin.y, 1050, 700), display: true)
        self.mainWindowController.window?.titlebarAppearsTransparent = true
       // Crashing after this??
        self.mainWindowController.showWindow(self)
    }

As junkpile says, if you can symbolicate the crash report, you'll have a clearer idea of what's going on. However, you can see from the back trace that the window-opening machinery (apparently) got as far as sending 'viewDidAppear:' to your view controller subclass, then there were 4 levels of calls from that method. Looking at what 'viewDidAppear' does might me a good place to start.

I believe 

EXC_CORPSE_NOTIFY
is what you get in Swift when you reference an "unowned" property that's no longer a valid pointer.

Not quite. 

EXC_CORPSE_NOTIFY
is part of the machine-exception-to-crash-log execution chain, and you’ll find it in most crash logs. The critical thing here is 
EXC_BAD_INSTRUCTION (SIGILL)
, which indicates that the process executed an illegal instruction. The most common cause for that is that the compiler inserted this illegal instruction in such a way that it’s executed if one of the compiler’s safety checks fails. This can happen in C-based languages, but is very common in Swift (for example, when you unwrap a nil optional, or access outside of an array’s bounds).
