title: Segue in Navigation Controller Xcode 10
body: <p>I am a beginner in terms of coding in swift.</p>
  
  <p>I use a navigation controller to navigate between different ViewControllers. On each ViewController I have buttons with IBOutlets connected to the ViewControllers to trigger a segue to go to the next ViewController.</p>
  
  <p><strong>WHAT I WANT TO HAPPEN:</strong> 
  Inside of the IBOutlets I use the "perform segue with identifier" fuction to trigger the segue action only if the button was pressed.</p>
  
  <p><strong>THE PROBLEM:</strong>
  The segue action always triggers two times.. so how can I disable the automatic segue action ? </p>
