Positioning shape at the edge of the screen

Question

Given a PlaygroundBook page, how can you position a SpriteKit node to the right edge of the screen of the liveView so it "snaps" there?

So far I've tried to position the node like so:

// Context: class _: SKScene 
// myNode.frame.size == CGSize(width: self.frame.width / 4, height: self.frame.height)

myNode.position = CGPoint(x: self.frame.maxX - myNode.frame.size.width / 2, y: self.frame.midY)

If I were to position the node at CGPoint(x: self.frame.maxX, y: self.frame.midY), I would expect its center to be right at the right edge of the screen, cropping out half of the node: that doesn't happen, the node gets placed someplace where it isn't visible at all.

Additionally:

the node positions right in the middle if I were to use frame.midX as the x coordinate
the node positions at the bottom-left corner of the screen if I were to use (0, 0) as the position.

What am I missing? Thank you.

(0,0) is center of the scene, so (-midx,-midy) is top left, (midx,midy) is bottom right — Knight0fDragon, Mar 21 '19 at 14:04
Updated the answer. `(midX, midY)` positions right at the center. — Johnny Bueti, Mar 21 '19 at 14:05
`(self.view as! SKView).bounds.size`, `self.view` is the ViewController's object. — Johnny Bueti, Mar 21 '19 at 14:08
hmmm, I wonder if the view size is the same size as the liveView window — Knight0fDragon, Mar 21 '19 at 14:10
I've just printed the `view.bounds.size` for both `.sideBySide` and `.fullScreen` and it seems to be identical; same for `(midX, midY)`... if, however, you rotate the iPad with the node being at `(midX, midY)` it repositions automatically to the center of the screen... ? What? — Johnny Bueti, Mar 21 '19 at 14:16
that is definitely weird, change the scalemode to `.fill`, and see if things pop up. It feels like you are getting cropping from `.aspectFill`, but I do not understand why you would be. — Knight0fDragon, Mar 21 '19 at 14:18
For both `.fill` and `.aspectFill` the `(midX, midY)` values don't change... this is pure black magic. — Johnny Bueti, Mar 21 '19 at 14:20
well the value wouldnt change, but it should display on the screen — Knight0fDragon, Mar 21 '19 at 14:25
To which class does `myNode` belong? If it is an SKSpriteNode, you can use the `anchorPoint` property to manipulate where the sprite node should be positioned. — jraufeisen, Mar 25 '19 at 10:00
