title: Is it possible to zoom in/out the text editor in Xcode 9.1 using the trackpad?
body: <p>I'm editing a simple python script in Xcode. </p>
  
  <p>When using TextEdit, I can zoom in/out using the trackpad by pinching with two fingers. </p>
  
  <p>Can a similar behaviour be achieved in Xcode without using:
   <strong>cmd+</strong> or <strong>cmd-</strong>
  ?</p>
