Experimentation

To help you experiment with QuickLayout, the macro provides a way to disable QuickLayout on a specific view. This is achieved by overriding the isBodyEnabled property.

@QuickLayout
final class ExperimentedView: UIView {

  override var isBodyEnabled: Bool {
    featureFlags.isQuickLayoutEnabled
  }

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

  var body: Layout {
    ...
  }

  override public func layoutSubviews() {
    super.layoutSubviews()
    /// Note: you don't need to call
    /// _QuickLayoutViewImplementation.layoutSubviews(self)
    /// because it's automatically injected by the macro.
    if !isBodyEnabled {
      imperativeManualLayoutSubviews()
    }
  }

  override public func sizeThatFits(_ size: CGSize) -> CGSize {
    if !isBodyEnabled {
      imperativeManualSizeThatFits(size)
    }
    /// OK to call for migration.
    _QuickLayoutViewImplementation.sizeThatFits(self, size: size) ?? .zero
  }
}
