Hey there, iOS developers! 👋 If you've been curious about bringing AI-powered code suggestions into your Xcode workflow, you're in the right place. Today, I'll walk you through setting up GitHub Copilot in Xcode - it's easier than you might think!

What is GitHub Copilot?

Before we dive in, let's quickly cover what Copilot brings to the table. Think of it as your AI pair programmer that:
