    personViewController.name = person.name
    personViewController.imageName = person.image

    self.presentViewController(personViewController, animated: true, completion: nil)
}

PersonViewController

import UIKit

class PersonViewController: UIViewController {

@IBOutlet weak var personImage: UIImageView!
@IBOutlet weak var overlayImage: UIImageView!
@IBOutlet weak var nameLabel: UILabel!

var name: String?
var imageName: String?

override func viewDidLoad() {
    super.viewDidLoad()

    // Do any additional setup after loading the view.
    self.personImage.image = UIImage(named: imageName!)
    self.overlayImage.image = …
