Hello, Devs! On the last years with my team, were are using Storyboards. From now on we get started with View Code. I was writing the and learning the best way to do that and I have some doubts around it. In particular case I writing something like that (Is not done from while) import UIKit class TopView: UIView {        override init(frame: CGRect) {         super.init(frame: frame)         setupTopView()     }          required init?(coder: NSCoder) {         fatalError("init(coder:) has not been implemented")     }     func setupTopView() {         self.addSubview(contentTopView )     }     let contentTopView: UIView = {         let topView = UIView(frame: CGRect(x: 0, y: 0, width: 80, height: 80))         topView.backgroundColor = .gray         topView.layer.cornerRadius = 12         topView.layer.shadowRadius = 1.0         topView.layer.shadowOpacity = 0.5         topView.layer.shadowColor = UIColor.lightGray.cgColor         topView.layer.shadowOffset = CGSize(width: 0, height: 10)                   return topView     }() } This is the best way to write View Code? Why I should to use () on the final block of the contentToTopView after the }? Thanks, Cheers!!!

Hello from NY o/ On the many projects, I was working out with Storyboards. From now on, I'm beginning with View Code and I'm trying to change the size of the UIView as something like that: e.g class ViewController: UIViewController { // MARK: - Subviews private lazy var containerView: UIView = { let view = UIView()   view.backgroundColor = UIColor.green view.frame.size.height = 200.0 view.frame.size.width = 300.0   view.sizeToFit() view.translatesAutoresizingMaskIntoConstraints = false return view }() // MARK: - Lifecycle override func viewDidLoad() { super.viewDidLoad() view.backgroundColor = UIColor.white      view.addSubview(containerView) containerView.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true containerView.centerYAnchor.constraint(equalTo: view.centerYAnchor).isActive = true } } And the size of the View is not sizing. I need use CGRect to change the size of the UIView? But how to center with auto layout when CGRect(x: 0, y: 0, height: 200, width: 350)? The x & y stay to hard to keep center x & center y at any screen size? Thanks a lot for you help. Cheers.

Hello Devs!! Hello from NY o/ On this particular case, I'm make some studying about Dependency Injection and I'm just making a couple mockups to improve my lessons. By the way, I would like understand more deep why the ...{ coder in ... at my closure be represented a casting with my another class as something like this below: ... import UIKit class ViewController: UIViewController {     override func viewDidLoad() {         super.viewDidLoad()         self.title = "Movie"     }     @IBAction func inject(_ sender: Any) {                  let movie = Movie(title: "GoldenEye 007", genre: "Action", poster:  imageLiteral(resourceName: "007 Goldeneye"))                  guard let moviesDetailsVC = self.storyboard?.instantiateViewController(identifier: "ShowMore", creator: { coder in             return MoviewsDetailViewController(coder: coder, movie: movie)                      }) else {             fatalError("MoviesViewController has not been implemented")         }                  self.navigationController?.pushViewController(moviesDetailsVC, animated: true)     }      } ... That's my another class: import UIKit class MoviewsDetailViewController: UIViewController {          @IBOutlet weak var posterImageView: UIImageView!     var movie: Movie     override func viewDidLoad() {         super.viewDidLoad()         // Do any additional setup after loading the view.         self.title = movie.title         self.posterImageView.image = movie.poster     }          init?(coder: NSCoder, movie: Movie) {         self.movie = movie         super.init(coder: coder)              }          required init?(coder: NSCoder) {         fatalError("init(coder:) has not been implemented")     }      } Cheers!!!
