Install These Skills Before Codex Touches Your Xcode Project



Hey Reader,


This week I'm sharing the Skills and Plugins I'd install before letting Codex touch an Xcode project.

These skills prevent your agent from writing deprecated code (that they trained on), and push agents to use modern Swift app development.

With these skills your agents can make any app:

Grab skills for:

  • Swift + SwiftUI
  • Swift Concurrency
  • Liquid Glass
  • iOS + macOS development

Plus, OpenAI just updated the Build iOS Apps Plugin, and published a new Build Mac Apps Plugin with telemetry (debug logging). These official plugins combine multiple skills, MCPs, and tools.

  4. Adam Lyttle created a new agent skill to help improve your iOS app onboarding process (based on what works).
  5. YarnPal made ~$690K in March. Ariel from App Figures breaks down this breakout app. Ads are driving revenue to a product that customers love.

New App Update!

I updated my coundown timer for Tahoe!

To celebrate, Super Easy Timer is free for a limited time. Download it now and you'll get it for free for life.

Here's how I use Super Easy Timer:

  • Focused writing or coding (25 minutes)
  • Knowing when I need to leave for an appointment (5pm)
  • Try: "5 min 30 sec", "12:30pm", "2 days 3 hours"

I have future updates planned for Full Screen overlay support based on Super Easy Slides (which I use for my YouTube videos).

If you enjoy either app, please leave an App Store review. Every review helps — appreciate it.

Thanks for downloading my apps — have a great day!

Talk soon,

P.S. If you want a simple app workflow, download my skill AppCreator. Use AppCreator so both you and your agent can build apps from the terminal using Makefiles.

P.P.S. Next week: monetization strategies that are working right now.

Hey Reader, One indie dev was stuck at $250 MRR for 13 years. Then he started following Viktor Seraleev, changed 5 things, and hit $5,031 MRR a year later. The fix? Just better packaging.

Hey Reader, What workflow is best for Codex and Xcode? There are a lot of tools you can configure to work with Xcode, but they might be costing you context (or wasting time). Last year, I started using Makefiles with my agents. A Makefile is a script that can be used to build or run anything (like xcodebuild). I love that you can extend Makefile targets to support variables to hyper focus testing with agents. It's better for Codex to make one tool call that does exactly what you need, rather...

App Store Screenshots

Hey Reader, My last app launch was a flop. I wrote the App Store copy after I’d already submitted for App Review — and I knew it. If you’re in that same boat, that’s okay. But don’t stop there. This week’s article breaks down the research workflow I should have used from the start: using AI and competitor reviews to write copy before you design a single screenshot.
