I want stepper like this one

And I have written below code:

func setupProgressBarWithDifferentDimensions() {
        progressBarWithDifferentDimensions = FlexibleSteppedProgressBar()
        progressBarWithDifferentDimensions.translatesAutoresizingMaskIntoConstraints = false
        self.view.addSubview(progressBarWithDifferentDimensions)

        // iOS9+ auto layout code
        let horizontalConstraint = progressBarWithDifferentDimensions.centerXAnchor.constraint(equalTo: self.view.centerXAnchor)
        let verticalConstraint = progressBarWithDifferentDimensions.topAnchor.constraint(
            equalTo: view.topAnchor,
            constant: 450
        )
        let widthConstraint = progressBarWithDifferentDimensions.widthAnchor.constraint(equalToConstant: 320)
        let heightConstraint = progressBarWithDifferentDimensions.heightAnchor.constraint(equalToConstant: 25)
        NSLayoutConstraint.activate([horizontalConstraint, verticalConstraint, widthConstraint, heightConstraint])

        progressBarWithDifferentDimensions.numberOfPoints = 5
        progressBarWithDifferentDimensions.lineHeight = 5
        progressBarWithDifferentDimensions.progressLineHeight = 6
        progressBarWithDifferentDimensions.radius = 16
        progressBarWithDifferentDimensions.progressRadius = 16
        progressBarWithDifferentDimensions.delegate = self
        progressBarWithDifferentDimensions.selectedBackgoundColor = progressColor
        progressBarWithDifferentDimensions.backgroundShapeColor = UIColor.lightGray
//        progressBarWithDifferentDimensions.centerLayerDarkBackgroundTextColor = UIColor.green
//        progressBarWithDifferentDimensions.centerLayerTextFont = UIFont.systemFont(ofSize: 17)
        progressBarWithDifferentDimensions.selectedOuterCircleLineWidth = 0.0

        progressBarWithDifferentDimensions.completedTillIndex = 2
        progressBarWithDifferentDimensions.currentIndex = 2

        progressBarWithDifferentDimensions.stepTextColor = UIColor.yellow
        progressBarWithDifferentDimensions.currentSelectedTextColor = UIColor.white
        progressBarWithDifferentDimensions.centerLayerTextColor = UIColor.gray
    }
