Plot nodes along a UIBezierPath in spritekit

i'm currently developing a game in spritekit which has a game level map. I'm using an UIBezierPath for the pathway i want the level nodes to follow, the only problem I have is trying to plot them along the path and was wondering how I go about adding them to the scene so they get added to the path way and each one is individually spaced 50 apart from the last one that was plotted before it. currently I have this:

My Code

let path = UIBezierPath()
path.move(to: CGPoint(x: -200, y: 0))
path.addCurve(to: CGPoint(x: 0, y: 0), controlPoint1: CGPoint(x: 0, y: 0), controlPoint2: CGPoint(x: -200, y: 0))
path.addCurve(to: CGPoint(x: 140, y: 0), controlPoint1: CGPoint(x: 60, y: 180), controlPoint2: CGPoint(x: 140, y: 10))
path.addCurve(to: CGPoint(x: 280, y: 0), controlPoint1: CGPoint(x: 220, y: -180), controlPoint2: CGPoint(x: 280, y: 0))
path.addCurve(to: CGPoint(x: 440, y: 0), controlPoint1: CGPoint(x: 400, y: -300), controlPoint2: CGPoint(x: 440, y: 0))

let shapeNode = SKShapeNode(path: path.cgPath)
    shapeNode.strokeColor = UIColor.white
    addChild(shapeNode)


for i in 1...5 {

   let level1 = mapLevelTiles()
   level1.createAndDisplay(Data: lev3)
   level1.position = CGPoint(x: 0 + level1.levelImageNode.size.width * 1.5 * CGFloat(i), y: path.cgPath.currentPoint) //path.cgPath.currentPoint
   level1.zPosition = 10
   addChild(level1)

}

The code above doesn't achieve what I want because it only allows me to get the end point of the last line in the path. How do I plot the nodes along the path that I have drawn?
