Wtf does this do

This repository contains a simple iPhone app that recreates the classic Magic 8 Ball toy. You ask a question, give the phone a shake (or tap), and it displays a random answer like "Yes," "No," or "Ask again later." At a high level, the app works by presenting a basic on-screen interface with an 8 ball graphic. When the user interacts with it, the code picks a response from a predefined list and shows it on the screen. The project is written in Objective-C, which is an older programming language historically used to build iOS apps before Apple introduced Swift. The creator built this as a quick experiment for a Thursday meetup, so it's really aimed at people learning iOS development or someone who wants a very basic example of how an app handles user input and displays a response. A beginner studying how mobile apps work could look at this code to see a straightforward, concrete example. The README is extremely sparse and notes that the app is experimental and constantly changing, advising users to proceed with caution. It doesn't go into detail about specific features or setup instructions. Because it was built as a class or meetup project, it likely trades polish and completeness for simplicity, serving as a learning exercise rather than a production-ready application.
