Not allowed to use property observer

I want two SKSpriteNodes to be at the same position and static to each other. I first tried setting this up in the update() function.

sprite1.position = sprite2.position

It gives sprite1 the position of sprite2 one frame before. With high speeds (changes in sprite2's position ) it gets clear they are not static to each other. I then tried using a property observer:

sprite2.position = sprite2Position{ didSet{ sprite1.position = sprite2.position } }

I'm not allowed to do this. Xcode says I have to separate multiple statements on line.

To make sure the sprites have the same position, set the position after physics and SKActions have been simulated. Do this in the didFinishUpdate() method of SKScene:

override func didFinishUpdate() {
    sprite1.position = sprite2.position
}
