I'm kind of new to Swift programming, so this question might look silly!

I have a new viewController named InfoViewController and I have connected it to the visual view controller in main.storyboard as the figure below:

As you can see, the view controller in main.storyboard is connected to `InfoViewController.swift`

However, when I insert the UITextView into the InfoViewController.swift, it does not recognize it as the following pic.

What is the problem, any help is highly appreciated
