How to automatically set MyCellView frame

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
       // how to set MyCellView frame
        view.addSubview(MyCellView())
    }
}

@QuickLayout
class MyCellView: UIView {
    
    let titleLabel = UILabel(text: "titleLabel")
    let subtitleLabel = UILabel(text: "subtitleLabel")
    
    let imageView = UIImageView()
    
    var body: Layout {
        HStack {
            VStack(alignment: .leading) {
                titleLabel
                Spacer(4)
                subtitleLabel
                imageView.resizable()
            }
            Spacer()
        }
        .padding(.horizontal, 16)
        .padding(.vertical, 8)
    }
}

Hi @zeroskylian, thanks for trying QuickLayout. There are multiple way of achieving what you need:

1. Define the body and call body.applyFrame in the viewDidLayoutSubviews.

class ViewController: UIViewController {

  let cellView = MyCellView()

  override func viewDidLoad() {
    super.viewDidLoad()
    view.addSubview(cellView)
  }

  var body: Layout {
    ZStack {
      cellView
    }
  }

  override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()
    body.applyFrame(view.bounds.inset(by: view.safeAreaInsets))
  }
}

You also can achieve that without QuickLayout as well just call the sizeThatFits and set the returned size on cellView.

class ViewController: UIViewController {

  let cellView = MyCellView()

  override func viewDidLoad() {
    super.viewDidLoad()
    view.addSubview(cellView)
  }

  override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()
    let cellSize = cellView.sizeThatFits(view.bounds.inset(by: view.safeAreaInsets).size)
    cellView.frame = CGRect(origin: .zero, size: cellSize)
  }
}

Let me know if you have any further questions. Cheers!
