Comment créer de l'ovalin avec une bordure en pointillés dans UiBezierPath
class DashedCircleView: UIView {
private var shapeLayer: CAShapeLayer = {
let shapeLayer = CAShapeLayer()

shapeLayer.lineCap = .round
shapeLayer.lineDashPattern = [20, 60]
return shapeLayer
}()

let rect = bounds.insetBy(dx: shapeLayer.lineWidth / 2, dy: shapeLayer.lineWidth / 2)
let radius = min(rect.width, rect.height) / 2
let center = CGPoint(x: rect.midX, y: rect.midY)
let path = UIBezierPath(arcCenter: center, radius: radius, startAngle: 0, endAngle: .pi * 2, clockwise: true)
