Manual Layout Integration

The @QuickLayout macro is available for all view instances, but not view controllers. When needed, you can still use QuickLayout without this macro. In that case, you will need to manually manage the view hierarchy and override the layoutSubviews and sizeThatFits methods. The snippet below demonstrates a view that does not utilize the @QuickLayout macro, but still utilizes a declarative syntax for layout.

import QuickLayout

final class MyView: UIView {

  private let label = {
    let label = UILabel()
    label.text = "Hello World!"
    return label
  }()

  private let image = {
    let image = UIImageView()
    image.image = UIImage(systemName: "globe.americas")
    return image
  }()

  init() {
    super.init(frame: .zero)
    self.addSubviews {
      label
      image
    }
  }

  var body: Layout {
    HStack {
      label
      Spacer(8)
      image
    }
  }

  override func layoutSubviews() {
    super.layoutSubviews()
    body.applyFrame(bounds)
  }

  override func sizeThatFits(_ proposedSize: CGSize) {
    body.sizeThatFits(proposedSize)
  }
}
