Round image view with gradient border color

UIImageView+Ext.swift

import UIKit

extension UIImageView {
    
    func addCircleGradiendBorder(_ width: CGFloat) {
        let gradient = CAGradientLayer()
        gradient.frame =  CGRect(origin: CGPoint.zero, size: bounds.size)
        let colors: [CGColor] = [UIColor.supSoftGreenThree.cgColor, UIColor.supSoftGreenTwo.cgColor,
                                 UIColor.supSoftGreen.cgColor, UIColor.supTea.cgColor,
                                 UIColor.supAquaMarineTwo.cgColor, UIColor.supAquaMarineThree.cgColor,
                                 UIColor.supAquaMarineFour.cgColor, UIColor.supAquaMarineFive.cgColor,
                                 UIColor.supAzureThree.cgColor, UIColor.supAzureFour.cgColor, UIColor.supAzure.cgColor]
        gradient.colors = colors
        gradient.startPoint = CGPoint(x: 1, y: 0.5)
        gradient.endPoint = CGPoint(x: 0, y: 0.5)
        
        let cornerRadius = frame.size.width / 2
        layer.cornerRadius = cornerRadius
        clipsToBounds = true
        
        let shape = CAShapeLayer()
        let path = UIBezierPath(ovalIn: bounds)
        
        shape.lineWidth = width
        shape.path = path.cgPath
        shape.strokeColor = UIColor.black.cgColor
        shape.fillColor = UIColor.clear.cgColor // clear
        gradient.mask = shape
        
        layer.insertSublayer(gradient, below: layer)
    }
    
}

great.thanks
