Swift SKNode position help - sprite position always 0,0 as it moves - ios

Question

Problem: I’m working in swift playground on an iPad Pro.
I’d like to get the current position coordinates of an SKSpriteNode with attached physicsBody as they move around the screen. No matter what it try, the sprite position returns 0,0, despite seeing it move across the screen.
I’ve attempted various implementations of convert(_:to:) and convert(_:from:) but the sprite position always ends up 0,0. My understanding is that this isn’t really necessary in the specific case here since the sprite is the direct child of the scene so the sprite’s position property should already be what it is in the scene coordinate system.
I’ve spent a lot of googling time attempting to figure this out without much success which makes me think I’m asking the wrong question. If so, please help me figure out what the right question to ask is!
The touch position print returns the correct position relative to the initial screen size. That’s what I’d like to get for the sprite.
Disclaimer - i don’t do this professionally so please forgive what I’m sure is ugly coding!
