Overring touchesEnded in SKSpriteNode - check if any node in scene is under point

I've had to override touchesBegan and touchesEnded in an SKSpriteNode subclass that has children nodes (because I want to propagate a touch event on the child node)

touchesBegan is working fine, but the problem I'm having is in touchesEnded checking that the same sprite is still under a users finger.

No matter what I try I never get a reference to 'self' in the node list of places at that point

 override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) {
        print("touched ended")
        for t in touches {
            let allNodes = nodes(at: t.location(in: self.scene!))
            print(allNodes)
        }
    }

Should t.location(in: self.scene!) return what I'm looking for? I've also tried self.scene?.view but this also returns an empty node list.

How could I go about checking that the touchesEnded touch was still on this SKSpriteNode? or indeed if they have moved their finger check if it's over an entirely different node? I guess I need to convert this back to the whole scene coordinates some how which I thought t.location(in: self.scene.view)) would do. My other thought was using some kind of delegate method on the main scene file, but would the touch.location be relative to the node that was tapped?

You're checking nodes in self.. self here IS the subclassed parent node.. You should check for nodes in your main scene, which would show the subclassed node properly:

let allNodes = self.scene!.nodes(at: t.location(in: self.scene!))

You can also use the various convert and convertPoint methods to do this.
