Convenient to add width height ratio constraints

Before

UILabel().do { label in
  label.backgroundColor = .darkGray
  view.addSubview(label)
  label.snp.makeConstraints { make in
    make.width.equalTo(100)
    make.height.equalTo(label.snp.width).multipliedBy(0.5)
    make.center.equalToSuperview() 
  }
}

After

UILabel().do {
  $0.backgroundColor = .darkGray
  view.addSubview($0)
  $0.snp.makeConstraints { make in
    make.width.equalTo(100)
    make.height.equalToSelf(\.width).multipliedBy(0.5)
    make.center.equalToSuperview()
  }
}
