Answer 1

You have to create IBOutlet Collection like as

@IBOutlet var labels: Array<UILabel>!

For more reference of code check this question :

Answer 2

Follow these steps to create an array of outlets an connect it with IB Elements:

• Create an array of IBOutlets
• Add multiple UIElements (Views) in your Storyboard ViewController interface
• Select ViewController (In storyboard) and open connection inspector
• There is option 'Outlet Collections' in connection inspector (You will see an array of outlets there)
• Connect if with your interface elements

-

class ViewController2: UIViewController {


    @IBOutlet var collection:[UIView]!


    override func viewDidLoad() {
        super.viewDidLoad()
    }
}
