I started working with xcode a few days ago, and today I tried to connect a textview from the main storyboard to the viewcontroller, but I figured out that its not working.
I'm using Xcode 9.2 I had my ViewControlled refactored into sections using the "extension" keyword. It appears you can't control drag into an extension of a ViewController. If you go up to the top part that is in the class definition, control dragging works fine (assuming you did the other things in this thread about making sure the right class is associated with the view controller.
