title: Swift: Load .Xib with animation
body: <p>Currently I am loading a new .Xib of class CreateAnAccount: UIView form a button pressed on another view.</p>
  
  <p>At the moment it immediately switches to the Xib which is great, but is there a way of animating this? below is the code in the button.</p>
  
  <pre><code>    @IBAction func createAnAccount(sender: AnyObject) {
      let createAnAccountView = NSBundle.mainBundle().loadNibNamed("CreateAnAccount", owner: self, options: nil)[0] as! CreateAnAccount
      createAnAccountView.frame = CGRectMake(0, 0, UIScreen.mainScreen().applicationFrame.size.width, UIScreen.mainScreen().applicationFrame.size.height + 20)
      createAnAccountView.loginHandler = loginHandler
      self.addSubview(createAnAccountView)
      println("Create An Account Pressed")
  }
  </code></pre>
