title: Calling a phone number in swift
body: <p>I'm trying to call a number not using specific numbers but a number that is being called in a variable or at least tell it to pull up the number in your phone. This number that is being called in a variable is a number that I retrieved by using a parser or grabbing from a website sql. I made a button trying to call the phone number stored in the variable with a function but to no avail. Anything will help thanks!</p>
  
  <pre><code>    func callSellerPressed (sender: UIButton!){
   //(This is calls a specific number)UIApplication.sharedApplication().openURL(NSURL(string: "tel://######")!)
  
   // This is the code I'm using but its not working      
   UIApplication.sharedApplication().openURL(NSURL(scheme: NSString(), host: "tel://", path: busPhone)!)
  
          }
  </code></pre>
