EXC_BAD_ACESS crash xcode - ios

Question

I'm getting this crash : link
in my app ,i did many search abou it but i didn't find how to solve it.
i also enabled Zombies object & Analyzer of xcode but without succes.
Here is my code :
import UIKit
class CameraViewController: UIViewController{
#IBOutlet weak var playerContainer: UIView!
#IBOutlet weak var imageView: UIImageView!
#IBOutlet weak var loading: UIActivityIndicatorView!
var device : GTLUserendpointGeneralCamera!
var myfoxCam : CloseliCameraDevice!
var retryToPlayCount = 0
override func viewDidLoad() {
super.viewDidLoad()
NSNotificationCenter.defaultCenter().addObserver(self,selector: "playerStatusChanged:",name: CameraPlayerStatusChangedNotification,object: nil)
NSNotificationCenter.defaultCenter().addObserver(self,selector: "playerStoppedDispose:",name: CameraPlayerStoppedNotification,object: nil)
}
override func viewDidAppear(animated: Bool) {
if(device.brand == "myfox"){
showLive()
}
}
override func viewWillDisappear(animated: Bool) {
MyFoxManager.sharedInstance.destroyPlayer()
}
deinit {
NSNotificationCenter.defaultCenter().removeObserver(self)
}
func showLive(){
loading.startAnimating()
MyFoxManager.sharedInstance.showLive(myfoxCam , image: self.imageView)
}
func playerStatusChanged(notification: NSNotification){
let waiting = notification.userInfo!["NSLocalizedDescription"] as! Bool
dispatch_async(dispatch_get_main_queue()) { [weak self] in
if let strongSelf = self {
if(waiting){
strongSelf.loading.startAnimating()
}else{
strongSelf.retryToPlayCount = 0
strongSelf.loading.stopAnimating()
}
}
}
}
func playerStoppedDispose(notification: NSNotification){
let code = notification.userInfo!["NSLocalizedFailureReason"] as! Int
dispatch_async(dispatch_get_main_queue()) { [weak self] in
if let strongSelf = self {
if(code & strongSelf.retryToPlayCount < 4){
strongSelf.retryToPlayCount = strongSelf.retryToPlayCount + 1
strongSelf.performSelector("showLive", withObject: nil, afterDelay: 2.0)
}
}
}
}
}
And
import UIKit
import Foundation
import CoreBluetooth
class MyFoxManager: NSObject {
static let sharedInstance = MyFoxManager()
var closeSDK : CloseliSDK!
var login = false
private override init() {
closeSDK = CloseliSDK(productKey: MyFoxAppId, withPassword: MyFoxAppSecret, serverType: "us")
}
func getCamera(device: GTLUserendpointGeneralCamera) -> CloseliCameraDevice? {
if(!login){
do {
try closeSDK.loginWithToken(device.appUrl, withAccount: device.url)
login = true
}catch{
return nil
}
}
do {
let myfoxCameras = try closeSDK.getCameraListError()
let myfoxCamera = myfoxCameras.filter{$0.deviceUUID == device.idDevice}
return myfoxCamera[0] as? CloseliCameraDevice
}catch {
return nil
}
}
func showLive(myfoxCam: CloseliCameraDevice, image: UIImageView){
closeSDK.preparetoLivePreview(myfoxCam , withUI: image)
}
func destroyPlayer(){
closeSDK.destoryPlayer()
}
}
Notification definition from third-party library :
/**
Notification for live preview status changing.
NOTICE: The notification may not be sent by CloseliSDK, so please fill parameter with sender to nil when adding observer
#param userInfo in NSNotification is a NSDictionary, value for NSLocalizedDescriptionKey is a NSNumber, YES means live preview is buffering, NO means live preview begin.
BOOL bWaiting = [[[notification userInfo] valueForKey:NSLocalizedDescriptionKey] boolValue];
*/
extern NSString *const CameraPlayerStatusChangedNotification;
/**
Notification for player stopped.
NOTICE: The notification may not be sent by CloseliSDK, so please fill parameter with sender to nil when adding observer
#param userInfo in NSNotification is a NSDictionary, value for NSLocalizedFailureReasonErrorKey is a NSNumber, represent the reason why it stopped, normally 0.
long stopReason = [[[notification userInfo] valueForKey:NSLocalizedFailureReasonErrorKey] longValue];
stopReason: 0x3261-means there is another client playing in p2p mode.
*/
extern NSString *const CameraPlayerStoppedNotification;
Any idea ?
Thanks in advance
