I cannot open another an assistent editor in Xcode, the top right plus button is greyed out (see screenshot).

  • I tried everything that may work to my knowledge.
  • I tried quitting and again force quitting Xcode.
  • I tried restating my computer
  • I finally tried to open the ViewController in AppCode in a different window and tried to connect the IBOutlet that way and Nothing worked

here is a ScreenShot enter image description here

    What is "my split screen button"? What is "not working"? – matt Jun 19 '21 at 20:46
  • This is a legit question, the issue is very confusing if you are new to Xcode. I vote for reopening. – de. Jun 20 '21 at 07:50

    The question is currently closed so I cannot post a proper answer. But click on the little icon with arrows pointing to toward each other in the top left above your editor view. It will "Unfocus" the editor. Keyboard: Command-Control-Shift-Return – de. Jun 20 '21 at 07:52

I am assuming you mean you cant open the Assistant editor. If so then:

  • Open story board
  • Know which file you want to open in the side by side view, aka assistant editor
  • option click or control click with your mouse on the desired file, then it will automatically open the file in the side view for you
  • Additionally you may also want to make sure you have linked correct files to your views in storyboard.
