There are numerous videos on YouTube and articles here on Medium about how this setup works, so my article is not going to be a full tutorial. Instead, I will write about my experience and a few takeaways.

For my second iOS application I wanted to build using the Cursor AI IDE, I wanted to build a simple stock tracking bot. In my initial Composer prompt I gave it a few requirements. These bullet points are a little more concise for this article.

7. When the monitoring is enabled, in a background thread fetch the current stock price every 5 minutes.

When I made my list of requirements, I started by putting them in a text file. I had a few starting sentences to tell the AI what kind of application I wanted to build. After those sentences I had a bulleted list of items like above to tell the AI in more detail each requirement I had.

So this is the application I got after the initial prompt and accepting the changes and saving them into my application.
