My breakpoint hits this line before it crashes:
let rootVC: UINavigationController = UIApplication.sharedApplication().keyWindow.rootViewController as UINavigationController
Following is the whole method that contains this line:
func session(session: MCSession!, didReceiveData data: NSData!, fromPeer peerID: MCPeerID!) {
//Check to see what kind of data is received
var dataReceived:AnyObject = NSKeyedUnarchiver.unarchiveObjectWithData(data)!;
if let newData = dataReceived as? String {
let rootVC: UINavigationController = UIApplication.sharedApplication().keyWindow.rootViewController as UINavigationController;
let topVC = rootVC.topViewController;
if let block = self.commandResolver[newData] {
block(topVC);
return;
} else {
println("Command resolver returns nil block");
}
} else if let newData = dataReceived as? NSDictionary {
let rootVC: UINavigationController = UIApplication.sharedApplication().keyWindow.rootViewController as UINavigationController;
let topVC = rootVC.topViewController as ViewController;
topVC.connected(true, withGroupName: newData["GroupName"] as String!);
} else {
println("Data is not a String");
}
}
My window.rootViewController is UINavigationController so it should not be nil if that is the problem. Can it be though?
I would really appreciate your help guys.
It's crashing in a background thread inside this block:
3 MultipeerConnectivity 0x2824ba26 __58-[MCSession syncHandleNetworkEvent:pid:freeEventWhenDone:]_block_invoke617 + 114
UIKit is generally not thread-safe and is "Main Thread only", so the fact that calling UIApplication.sharedApplication().keyWindow.rootViewController from a background thread crashes is not surprising. You probably want to dispatch this whole block back to the main thread.
This issue is getting on my nerves. Please see the crash report and help. In iOS 6 app is working fine. I am performing some operations. After 30 operations are completed I am experiencing this crash. This number can go till 20 also or 1 also. Attaching crash log with this. All the experts please help.

Can anyone tell me if this crashing stack appears to be caused by Reachability? I am running apple's latest implementation of Reachability, downloadable at https://developer.apple.com/library/ios/samplecode/reachability/Introduction/Intro.html
I have an app where ARC is not enabled by default (it is a legacy app) but I enable it on a per-file basis. I have enabled -fobjc-arc for Reachability.m
When I look at these threads, my code is nowhere to be found. I see some activity happening because of a WebHTMLView (probably the ad network view code currently on screen; it's not mine).
On Thread 10, I see a SCNetworkReachabilityDeallocate, then a dispatch_semaphore_wait_slow, and the crash happens on Thread 14 in libdispatch.
Do you think this crash is being caused by that Reachability code, and have I erred in using -fobjc-arc with Reachability.m?

This crash could be caused by just about any piece of code, including your own.
The stack trace indicates that a block has previously retained a pointer that is now being released with CFRelease. If the pointer was not properly retained in the first place - or was in the process of being dealloc-ed when it was originally retained, you could see this stack trace.
If you are accessing the pointer on one thread, but releasing it another, then you may well have the kind of race condition that can cause this kind of crash.
I'm updating a Game I have for the Mac and the update works fine while running through XCode.
I try to Distribute through Developer ID-signed Application so I can have a friend test it and when I run the app and also give them the app it crashes just after the Main Menu. Am I exporting it wrong? Why would it run fine through XCode and then I try to export it and it crashes every time?
Here is my error log:

scratch that.
after staring at this line for hours:
0 com.lasthaven.wordshufflemac 0x000000010bacc52a -[GameScene scrambleWord:] + 158 (GameScene.m:322)
I realized that the code consisted of a for loop and I couldn't figure out what was wrong with it! So in the end I forgot to initialize the int i in beginning of the for loop.
for(int i = 0; i < [word length]; i++ {
}
So for something so simple that caused a crash outside of XCode but not within it drove me nuts!
Thanks for reading!

Will be grateful for any suggestions how to fix this crash.
This crash happens because of a memory leak or zombie object. You are releasing an object which later on is accessed on the main thread. Best way to track this down is to use instruments leaks detection or NSZombie.
The leak could be anywhere in your app, the crash report can't give you a lot of help on that.
