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
