  SceneKit contains a recursive search for childNodes but SpriteKit inexplicably doesn't.
  So here's an extension that adds one, enjoy.

extension SKNode {
    func childNode(withName name: String, recursively: Bool) -> SKNode? {
        let directDescendent = childNode(withName: name)
        if(directDescendent != nil) { return directDescendent }
        
        for c in children {
            let child = c.childNode(withName: name, recursively: true)
            if(child != nil) { return child }
        }
        
        return nil
    }
}

I just realized that you actually can search recursively with special syntax (prepending the name with //.

For example: childNode(withName: "//NAME HERE")
