How do I change just the starting point of an existing UIBezierPath? .. and leave all other points the same?

How do I change just the starting point of an existing UIBezierPath? .. and leave all other points the same?

I have definitely seen many posts on how to do this .. honestly, I just do not understand many of them

My existing path has one .move(to:) and many .addLine(to:)

My goal is:

(1) replace the .move(to:) with .addLine(to:) and then (2) change one of the .addLine(to:) with .move(to:)

All other CGPoints stay the same.

In order to get the new starting point, I set:

savedPathPoint = myPath.currentPoint

when I stop the following motion.

At some point, I want to resume this following motion with the new starting point = savedPathPoint via

    myPath.move(to: savedPathPoint)

    let myAction = SKAction.follow(
                               myPath.cgPath,
                               asOffset: false,
                               orientToPath: true,
                               duration: 0.1)
    mySprite.run(myAction)

When I look at the above problem description, it really appears simple.

Nevertheless, its implementation alludes me.

Thanks bunches in advance for any hints whatsoever.
