Found a workaround by adding another subview to the incorrectly gray view: datePicker.subviews.first?.subviews.forEach { grayView in let view = UIView() view.translatesAutoresizingMaskIntoConstraints = false view.backgroundColor = .white grayView.insertSubview(view, at: 0) view.topAnchor.constraint(equalTo: grayView.safeAreaLayoutGuide.topAnchor).isActive = true view.bottomAnchor.constraint(equalTo: grayView.safeAreaLayoutGuide.bottomAnchor).isActive = true view.leadingAnchor.constraint(equalTo: grayView.safeAreaLayoutGuide.leadingAnchor).isActive = true view.trailingAnchor.constraint(equalTo: grayView.safeAreaLayoutGuide.trailingAnchor).isActive = true }
