Warning: UIAlertController is already presenting
<p>I am a novice in swift and XCode so please forgive me the probably really messy code!
When running my code I get the following warning:
    Warning: Attempt to present   on    which is already presenting </p>

<p>I have already checked the forum and found a post regarding  that issue....I applied the help suggested as in:</p>

<pre><code>if presentedViewController !== nil {
     self.presentViewController(alertController, animated: true, completion: nil)
} else{
     self.dismissViewControllerAnimated(false, completion: nil)
     self.presentViewController(alertController, animated: true, completion: nil)
}
</code></pre>

<p>However, it still gives me the same warning....So I guess I must have done something wrong there. It would be great if someone could help me out please :) Also if there any suggestion as to how I can "clean" up my code are appreciated :)</p>
