My cocoa app occasionally crashes with the above specific information. I'm sure that it's due to NSTableView display in my app but I can't figure out what's wrong. The crash report is as below. Can anyone tell what's going on?

I was working with Xcode last night, in morning I relaunch the XCode and it crash, an error appears.
I tried to delete the Preferences, cache, reinstall all... nothing.
But if I run Xcode from terminal with root privilege, it runs but Simulator doesn't work properly...
Error dump:

I'm seeing quite a few problems with the latest release of our software.
I'm getting customer complaints about crashes. Unfortunately though, I can't get any information from the crash reports. Here is one I receive the most:

The odd thing is that in the piece of code that produces the crash, the application is not doing anything. It's almost completely idle sitting there and waiting. This really makes it look like a memory corruption issue.
I've tried and profiled with Instruments to find any leaks. I also tried Xcode 7's new address sanitizer. To no avail.
Can anyone please give me a hint on what I could try to fix the issue?
I'm pretty sure that the issue only appears with release builds but I still couldn't pin down the reason of the crashes.
There are other stackoverflow questions concerning this, but my the solutions mentioned do not appear to apply to this problem. I have a NSTextField and I want to be notified everytime the text changes in the field. I have a NSViewController controlling the view that contains the NSTextField and it will be the observer.
My class simply looks like this:
import Cocoa
class ADDViewController: NSViewController
{
#IBOutlet weak var fieldText: NSTextField!
func fieldTextChanged( notification: NSNotification )
{
println( "fieldTextChanged" )
}
override var nibName: String?
{
return "ADDViewController"
}
override func viewDidLoad()
{
super.viewDidLoad()
NSNotificationCenter.defaultCenter().addObserver( self, selector: "fieldTextChanged:" as Selector, name: NSControlTextDidChangeNotification, object: fieldText )
}
}
The notification is being added and is firing. When I type a character into the field, I see in the stack trace:
#0 0x00007fff905880e9 in objc_msgSend ()
#1 0x00007fff8f27c45c in __CFNOTIFICATIONCENTER_IS_CALLING_OUT_TO_AN_OBSERVER__ ()
#2 0x00007fff8f16c634 in _CFXNotificationPost ()
#3 0x00007fff8fcf0aa1 in -[NSNotificationCenter postNotificationName:object:userInfo:] ()
#4 0x00007fff8f27c45c in __CFNOTIFICATIONCENTER_IS_CALLING_OUT_TO_AN_OBSERVER__ ()
#5 0x00007fff8f16c634 in _CFXNotificationPost ()
#6 0x00007fff8fcf0aa1 in -[NSNotificationCenter postNotificationName:object:userInfo:] ()
#7 0x00007fff8ab3deb1 in -[NSTextView(NSSharing) didChangeText] ()
right before it crashes. I did try changing the selector to:
#objc func fieldTextChanged( notification: NSNotification )
{
println( "fieldTextChanged" )
}
but, when I do this, it still doesn't work. What I see in the console:

The first question is, do I need the #objc in front of my selector? I do not believe this should be necessary as a NSViewController is a subclass of a NSObject and that appears to make #objc unnecessary. Is this correct?
What do I need to do to make this work?
I have a sample test project at:

Thank you.
In your applicationDidFinishLaunching, you are not keeping a reference to the view controller, so the object is released immediately. Then a notification is being sent to another object which took its place in memory (a __NSCFString in this case).
You need to store a strong reference to your view controller, e.g. as an instance variable.
I have an app on the Mac App Store, and I get these crash reports from my users which I cannot reproduce or figure out how to debug. It seem like something crashes due to NSManagedObjectContext reset, but it's not obvious, and users don't have a reproducible case. The main thread can have a different stack trace, but the non-main thread always has the same stack trace.

Any idea how to find out what's causing the issue and possibly fix it? I've tried enabling zombies, setting NSBindingDebugLogLevel to 1, and running Zombies instrument, but no luck.
This one is quite weird. I recently upgraded to Mountain Lion on my dev machine and now every time I bring up the main project window of my app it crashes. The strange thing is that it only happens on 10.8.3 and it only happen if I sandbox the app. I have another test machine running 10.8.2 (also Mountain Lion) and the crash does not happen. Also, if I recreate the app without sandboxing it does not crash. This app is actually created with an implementation of common lisp the uses a cocoa bridge called CCL.
Here are some of the reports I get in the console when my app crashes:

I am very confused by all this and I am wondering what could have changed in 10.8.3 that interacts badly with the sandboxing?
