Can't drag and drop item from storyboard to viewcontroller in xcode

Question

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.

Answer 1

Make sure you're in Assistant Editor Mode (When code and layout editor are side-by-side).

From Apple:

With Interface Builder open in the standard editor pane, select the control you want to configure, and click the Assistant Editor button () in the workspace toolbar. The assistant editor opens your object’s implementation file.

Control-drag from the control in Interface Builder to the implementation file. (In the screenshot, the assistant editor displays the implementation file of the view controller for the Warrior button.) Xcode indicates where you can insert an action method in your code.
