I'm having some trouble with my code preview. This project is part of a SwiftUI tutorial that I’m following from a website. But whenever I try to preview my screen, I get the error modal shown in the image.
It looks like an assert is failing on line 42 of Model Data.swift, based on looking at the crashing thread’s backtrace (“Thread 0 Crashed”) and then finding the frame with the lowest number, and then looking at the source information. Check out Analyzing a crash report for a full explanation of how to read a crash report.
