How do I detect a touch on a UIBezierPath and move a ball along that?

Question

How do I move a ball along a specific UiBezierPath? Is that possible?

I\'ve tried everything including doing a hit test using

-(BOOL)containsPoint:(

Swit: for @rakesh's answer

 func tapTargetForPath(_ path: CGPath) -> UIBezierPath? {
    let path = UIBezierPath(cgPath: path)
   guard let tapTargetPath = CGPath(__byStroking: path.cgPath,
           transform: nil,
           lineWidth: CGFloat(fmaxf(35.0, Float(path.lineWidth))),
           lineCap: path.lineCapStyle,
           lineJoin: path.lineJoinStyle,
           miterLimit: path.miterLimit) else {
            return nil
    }

    return UIBezierPath(cgPath: tapTargetPath)
}
