From Idea to iOS App in Minutes: Building with Codex and Xcode

June 12, 2026 at 06:00 PM

What if you could go from a rough idea to a working iOS app—UI, logic, and structure—in minutes instead of days?

In this session, you’ll see a live demo of using Codex to build a real iOS app using Xcode from scratch. Instead of treating AI as a gimmick, we’ll use it as a practical development partner—generating views, structuring code, and iterating quickly while staying inside Codex and using Xcode.

What This Session Covers:

  • How to prompt Codex to generate usable SwiftUI code using Xcode
  • Turning rough ideas into structured app features
  • Iterating on UI and logic without starting over
  • Where AI helps—and where it absolutely doesn’t
  • How to keep your codebase clean and maintainable

By the end of this session, you’ll walk away with:

  • A clear workflow for using Codex to build iOS apps
  • Practical prompt patterns that actually produce usable code
  • An understanding of how to integrate AI into your existing dev process
  • A working sample app (or the foundation of one)
  • A realistic sense of what AI can and can’t do for you as a developer

Show up to the session ready to learn and follow along. Maybe you'll even be inspired to release your first iOS mobile application!
