How to wait until SKAction.repeatForever completes the animation sequence in SpriteKit?

I have an animation running with SKAction.repeatForever animation loop, which runs an animation all over again for indefinite amount of time.

node.run(SKAction.repeatForever(
    SKAction.animate(with: animationFrames,
                     timePerFrame: timePerFrame,
                     resize: true,
                     restore: true)))

I have a user-triggered (with a touch) animation that I want to fire after the currently animated loop finishes. How can I catch when the current loop of SKAction.animate finishes and then stop, remove and replace the animation with a second one?

|--Loop1--|--Loop2--|--Loop3--|--...
                | user trigger here
                    | wait until Loop2 finishes and then replace the animation

Pseudo code of what kind of functionality I'm looking for:

... somewhere else ... {
    animatedNode.run(SKAction.repeatForever(SKAction.animate(...)))
}

func onTouch() {
    foreverRunningAnimation.waitUntilLoopFinishes() {
        animatedNode.removeAllActions()
        animatedNode.run(SKAction.repeatForever(SKAction.animate(< second animation>)))
    }
}

what? that makes no sense. You want to place a "random" delay after an animation phase ends? Why? That would make your repeat forever action look silly if the animation is pausing for a random duration – Knight0fDragon Sep 27 '18 at 17:21
You can run skaction.sequence as your repeat forever animation – E.Coms Sep 28 '18 at 01:27
@Knight0fDragon Let me update my question. – Markus Rautopuro Sep 28 '18 at 10:58

You dont want repeat forever then, you want a state machine – Knight0fDragon Sep 28 '18 at 11:15
Yes. Please answer with code. :) – Markus Rautopuro Sep 28 '18 at 11:37
