Memory Error in SwiftUI that goes way over my head - ios

Question

I'm learning SwiftUI over break for fun over youtube, trying to build a fun little app to learn stuff and i'm attempting to make a custom tab bar at the bottom to control views, and have objects (i made a Person object) that i owuld like to be able to access and modify throughout all my views. From what I can tell, I've achieved that, as it runs perfectly well as I expect it to on the Simulator, but when I try to run on my iPhone I get the error "Thread 1: EXC_BAD_ACCESS (code=257, address=0x481bdfee88082008)"
I'm not familiar with reading memory addresses, i'm just trying to screw around with building apps for fun with my downtime
