  <pre><code>    class OvalLayer: CAShapeLayer {
  
      let animationDuration: CFTimeInterval = 0.3
  
      override init() {
          super.init()
          fillColor = Colors.green.CGColor
          path = ovalPathSmall.CGPath
      }
  
      required init?(coder aDecoder: NSCoder) {
          fatalError("init(coder:) has not been implemented")
      }
  
  
      var ovalPathStart: UIBezierPath {
          let path = UIBezierPath(ovalInRect: CGRect(x: 0.0, y: 0.0, width: 100.0, height: 100.0))
  
          return path
      }
  }
  </code></pre>
  
  <p>Now I need to add a text to middle of this circle, I tried to find it on google but nothing that works fine. I am not sure if it's possible or not, can anyone help me if it's possible?</p>
