If no internet connection go to rootviewcontroller in swift

Question

I am checking if there is or not internet connection before calling any service method. If there's no internet, I am showing an alert and if I click ok button I want to go to root view controller.

Here's my code:

if TLReachability.isConnectedToNetwork() == true{
    // do here 
} 
else {
    let navigationController = UIApplication.sharedApplication().keyWindow?.rootViewController as! UINavigationController
    let mainStoryboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
    let changeViewController = mainStoryboard.instantiateViewControllerWithIdentifier("TLLoginViewController") as! TLLoginViewController
    navigationController.presentViewController(changeViewController, animated: true, completion: nil)
}

What's your question exactly, are you getting a crash? What is the result of your code example? — koen, Mar 16 '16 at 12:03

Your code sample doesn't seem connected to your question. Where are you testing your connection? How are you trying to return to the root? — Phillip Mills, Mar 16 '16 at 12:10
@Ravi: please edit your code example above with exactly what you are doing, don't use short snippets. — koen, Mar 16 '16 at 12:12

let alert:UIAlertController = UIAlertController.init(title: "ALERT", message: "NO INTERNET", preferredStyle: UIAlertControllerStyle.Alert)
alert.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.Cancel, handler: { action -> Void in
    let rootViewController = mainStoryboard.instantiateViewControllerWithIdentifier("RootViewController") as! RootViewController
    navigationController.presentViewController(changeViewController, animated: true, completion: nil)
}))
self.presentViewController(alert, animated: true, completion: nil)

Try calling your code on the main thread:

dispatch_async(dispatch_get_main_queue(), {
  let navigationController = UIApplication.sharedApplication().keyWindow?.rootViewController as! UINavigationController 
  navigationController.popToRootViewControllerAnimated(true)
})
