What we're building
This tutorial builds one real app, end to end: 4Notice, a small SwiftUI sticky-notes app — four notes, always at hand — for macOS and iOS from shared sources. It is deliberately tiny: the app is not the point. The point is the way it gets built, because the same way scales to apps that are not tiny.
By the end, you will have gone from an empty folder to an App Store submission, and along the road you will have:
- set up a project that a terminal agent can work on productively — plan, board, actions, all as files in the repo;
- learned to make steady progress with plans and tickets, and to keep the history honest with atomic commits;
- imported skills from a source and taken them through expand → execute → evaluate;
- exported your own skill — a workflow you learned while building — into your own Speccify work repo, where your next project will find it;
- localized the app, wired up fastlane and App Store Connect automation, and run pre-release checks before uploading.
The three tools
Section titled “The three tools”| Tool | Role in this tutorial |
|---|---|
| Claude Code | the agent: implements tickets, writes tools, commits |
| iKanban AI | the owner’s cockpit: board, plans, skills, toolbar actions |
| Speccify | the skill/tool manager: sources, expand, check, export |
None of them is load-bearing for the result: everything ends up as plain files and ordinary Xcode builds. That’s a feature — it means you can inspect every step, and swap any tool later.
How to read this
Section titled “How to read this”The tutorial is honest about its origin: 4Notice is a real project, and each chapter was written after the corresponding step actually happened there. Chapters whose step hasn’t happened yet are visible as marked stubs — the arc is real, not projected. If you want the concepts behind any step, the reference sections (Fundamentals, Speccify, iKanban AI) go deeper; the tutorial links into them rather than repeating them.
First stop: what you need installed.
