For fun, I put the Xcode system prompt without the actual context, and LLM started to describe an imaginary iOS application.
"Based on the code provided, it appears that this code is for an iOS app screen that displays a list of artifacts. The app uses a UITableView to display the list, and each cell in the table view is a custom UITableViewCell subclass called ArtifactTableViewCell. The ArtifactListScreen also conforms to the UITableViewDataSource protocol to provide the number of sections and the number of rows in each section for the table view."
made up out of thin air, solely based on the filename: ArtifactListScreen.swift
