We’ll look at how to install and use these agent skills in Xcode, Claude Code, Codex, Gemini, and more. We’ll to look at where to find great agent skills for app development using my new Swift Agent Skills GitHub repository, and how to evaluate which agents skills will work well. And I’m also going to show you how agent skills are different from AGENTS files, and why you might want both.
The result will be that using AI to write, review, or test code will be so much better, whether you’re using SwiftUI, Swift concurrency, SwiftData, Swift Testing, or something else.
If you missed my previous video about how to build apps with AI, I suggest you start there – it walks you through using Xcode, Claude Code, Codex, and more, with lots of tips for getting the most from Xcode, configuring your terminal, getting the most from ChatGPT, and more.

Still here? Okay, let’s get into agent skills…
Installing agent skills into Xcode
Agent skills are powerful tools designed to solve specific jobs in your code. I’ve written agent skills to improve your SwiftUI code, to make the most of Swift Testing, to optimize your Swift concurrency code, and even to make sure you’re using SwiftData effectively – each skill does one thing, and does it well.Before we get into how agent skills work, I want you to see them in action because they are really transformative.
If you’re installing skills from the command line for tools like Claude Code or Codex, it’s easy. But when using Xcode, it might take a few more steps.
