Thanks it seems like I solved the issue. So scrollView.contentView.layer?.removeAllAnimations() doesn't do anything, maybe someone knows what I misunderstood there.
BUT:
I can create a new animation group, which also needs a very short duration (maybe also 0), so it seems like if I set just ScrollView.contentView.animator().setBoundsOrigin(NSMakePoint(0, scrollView.contentView.bounds.origin.y)) it is still using the set 2 second animation interval. Therefore setting the context duration to 0.0 will solve the issue:
NSAnimationContext.runAnimationGroup({ context in
context.duration = 0.00
scrollView.contentView.animator().setBoundsOrigin(NSMakePoint(0, scrollView.contentView.bounds.origin.y))
}) {
}
