Unable to connect IBOutlet from storyboard to UIView subclass

Question

I am able to right-click and drag from my custom UIView subclass file to the storyboard elements to connect them, but unable to do so the other way around. I believe this is

Answer 1

Create an outlet like this in Objective-C

@property (nonatomic, weak) IBOutlet UIView *view;

or as in swift 3

@IBOutlet weak var instruction: UILabel?

and then connect it as given in this image.

Sometimes the normal way of connecting action and outlet doesn't work due to subclassing. This way comes handy for such situations.
