Use cases

let label = UILabel()
let button = UIButton()
let simpleView = UIView()

let hstack = HStackView {
    label
    button
    simpleView
}

let label = UILabel()
let button = UIButton()
let simpleView = UIView()

let vstack = VStackView {
    label
    button
    simpleView
}

let refresh = Bool.random()
let refreshAnother = Bool.random()
let idx = Int.random(in: 1 ... 12)
HStackView {
  VStackView {
    UILabel()
    UIButton()
  }
  if refresh {
    VStackView {
      UIImageView()
      UIView()
    }
  }
  if refreshAnother {
    VStackView {
      UIImageView()
      UIView()
    }
  } else {
      UIView()
  }
  UIView().withSubViews {
    HStackView {

Sample

private lazy var registerActionStack = VStackView(spacing: minorSpacing, alignment: .fill) {
  registerButton
  UIView.spacer()
  loginButton
}

private lazy var registerPolicyStack = HStackView(spacing: mediumSpacing) {
  UIView.spacer()
  policyCircleButton
  tipLabel
  policyInfoButton
  UIView.spacer()
}

private lazy var contentStack = VStackView(spacing: mainMargin, alignment: .center) {
  sloganImageView
  loginLogoImageView
  registerActionStack
  UIView.spacer()
  registerPolicyStack
}

view.withSubViews {
  contentStack
}

contentStack.snp.makeConstraints {
  $0.top.equalTo(view.safeAreaLayoutGuide.snp.top).offset(topPadding)
  $0.leading.trailing.equalToSuperview().inset(horizontalPadding)
  $0.bottom.equalTo(view.safeAreaLayoutGuide.snp.bottom)
}

registerButton.snp.makeConstraints {
  $0.width.equalTo(view).inset(horizontalPadding)
}
