open Skype in a Swift webview
<p>I want to open Skype in a Swift webview by just using a URL. Similar to something like the URL Scheme's provided by Apple for opening Apple Mail mailTo:// or telephone tel://.</p>

<p>1.) must i use the skype-API or just check if skype is installed with</p>

<pre><code>@IBAction func skypeMe(sender: AnyObject) {
   let installed = UIApplication.sharedApplication().canOpenURL(NSURL(string: "skype:")!)
   if installed {
    UIApplication.sharedApplication().openURL(NSURL(string: "skype:echo123?call")!)
   } else {
      UIApplication.sharedApplication().openURL(NSURL(string: "https://itunes.apple.com/in/app/skype/id304878510?mt=8")!)
   }
}
</code></pre>

<p>2.) how must i call this? (<strong>skype:username?call</strong>)</p>

<p>3.) my skype-login should be called automatically</p>

<p>4.) i want to choose the addressee</p>

<p>Is that possible?</p>
