How can I bring a SKSpriteNode to the front of all other node?
With UIView, I can use bringSubviewToFront to bring an uiview in front of other views.
You can't "bring it to front" but you can change the zPosition
of it.
The higher the zPosition
of the node the later it gets rendered.
So if you have three nodes with zPositions
of -1, 0 and 1 then the -1 will appear at the back. Then the 0. Then 1 will appear at the front.
If they all use the default zPosition
of 0.0 then they are rendered in the order they appear in the children array of the parent node.
You can read it all in the docs.
