NSString * string =  [[[UIDevice currentDevice] identifierForVendor] UUIDString];

//

let deviceID = UIDevice.currentDevice().identifierForVendor?.UUIDString 

//Swift 3

let deviceID = UIDevice.current.identifierForVendor?.uuidString

:

DeviceToken. DeviceToken - uniq .

:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    if ([[UIApplication sharedApplication] respondsToSelector:@selector(registerUserNotificationSettings:)])
    {
        [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];

        [[UIApplication sharedApplication] registerForRemoteNotifications];
    }
    else
    {
        [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
         (UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert)];
    }
    return yes;

}


- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken
{

   NSString *AppDeviceToken=[[NSString alloc] initWithFormat:@"%@",deviceToken];
    //NSLog(@"My token is: %@", self.AppDeviceToken);

   AppDeviceToken = [self.AppDeviceToken stringByReplacingOccurrencesOfString:@" " withString:@""];
   AppDeviceToken = [self.AppDeviceToken stringByReplacingOccurrencesOfString:@"<" withString:@""];
   AppDeviceToken = [self.AppDeviceToken stringByReplacingOccurrencesOfString:@">" withString:@""];

    NSLog(@"%@ Device Token is : %@",[[UIDevice currentDevice] name],AppDeviceToken);
}
- (void)application:(UIApplication*)application didFailToRegisterForRemoteNotificationsWithError:(NSError*)error
{
    NSLog(@"Failed to get token, error: %@", error);
}

- uniq .
