How to draw multiple horizontally circles in rectangle (UIButton or UIControl) Swift iOS

How to draw about three circle in horizontally area with main and ring color in rectangle. I need to create custom button with this circles, something like this:

Is there any good way to do this?

We can design such kind of views with UIStackView in very ease manner. Take a stackView, set its alignment to center, axis to horizontal and distribution to fill. Create a UILabel/UIButton/UIImageView or even UIView and add rounded radius and border to it. Finally, add those views to the main stackView. Try this.

override func viewDidLoad() {
    super.viewDidLoad()

    //Setup stackView
    let myStackView = UIStackView()
    myStackView.axis = .horizontal
    myStackView.alignment = .center
    myStackView.distribution = .fillEqually
    myStackView.spacing = 8
    view.addSubview(myStackView)

    //Setup circles
    let circle_1 = circleLabel()
    let circle_2 = circleLabel()
    let circle_3 = circleLabel()

    myStackView.addArrangedSubview(circle_1)
    myStackView.addArrangedSubview(circle_2)
    myStackView.addArrangedSubview(circle_3)

    myStackView.translatesAutoresizingMaskIntoConstraints = false
    myStackView.centerXAnchor.constraint(equalTo: view.centerXAnchor, constant: 0.0).isActive = true
    myStackView.centerYAnchor.constraint(equalTo: view.centerYAnchor, constant: 0.0).isActive = true
}

func circleLabel() -> UILabel {

    let label = UILabel()
    label.backgroundColor = UIColor.red
    label.layer.cornerRadius = 12.5
    label.layer.masksToBounds = true
    label.layer.borderColor = UIColor.orange.cgColor
    label.layer.borderWidth = 3.0

    label.widthAnchor.constraint(equalToConstant: 25.0).isActive = true
    label.heightAnchor.constraint(equalToConstant: 25.0).isActive = true

    return label
}
