Resizing a UITextView programmatically in Swift 2 to enlarge its width

EDIT: I post a screenshot of what I would like to implement in iPad and iPhone. When using the button in iPhone, the UITableView opens and has to cover a part of the UITextView.

enter image description here

I have a universal project for iPhone and iPad. In the main storyboard there are two controls, an UITextField and a UITableView. The UITextField keeps the left 1/3 portion of the screen and the UITableView the remaining part of the screen.

When in iPhone, I hide the UITableView and I would like that the UITextView keeps all the screen. Then, when the user taps on a button, the UITableView appears over the text field (I dismiss the UITableView as soon as the user selects a choice).

How can I have the tableView to enlarge in a way that its right border, go to the right border of the screen?

One way to implement what you described is to start with the TableView "outside" of the scene, with a negative Leading Space to the main view. Them when users press the button, the value of the Leading Space Constraint is set to zero.

Example:

enter image description here

Final result:

enter image description here

ViewController code:

class ViewController: UIViewController {

    @IBOutlet weak var tableViewLeadingMargin: NSLayoutConstraint!

    @IBAction func revealTableView(sender: UIButton) {
        UIView.animateWithDuration(
            3.0,
            animations: {
                self.tableViewLeadingMargin.constant = 0
                self.view.layoutIfNeeded()
            }
        )
    }
}

There's just one caveat: you'll need to adjust the width of the TableView programatically, based on the iPhone screen size.

The answer above the iPhone issue. For iPad, I'd suggest using Size Classes, creating a specific layout/constraints for them:
