Insights Gained from Using Claude Code for My iPhone App

Introduction

Delving into 'vibe coding'—a term suggesting a smooth and intuitive coding journey—revealed more complexities than anticipated. My venture into creating a comprehensive iPhone application with Claude Code underscored the significance of cautious planning, consistent backups, and rigorous testing. Here are ten crucial insights I wish I'd known beforehand.

Start Small and Gradual

Initially, I believed inputting full project specs into Claude at the outset would streamline development. However, this approach proved unwieldy. Instead, I found more success by tackling individual tasks. First, I got the AI to interpret NFC tags, then sequencing actions such as writing and verifying tags, and progressively adding capabilities like photo handling.

Document Every Session

A major breakthrough came from having Claude take meticulous notes post-session. It started with tracking the steps to enable NFC features and grew into complete session logs that included actions, decisions, and future plans. These notes became a crucial project compass.

Efficient Recap and Prep

This approach eradicated the time lost reacquainting myself with the project. Even sporadic work sessions became productive, facilitated by Claude’s ability to summarize past progress and recommend next steps. This allowed me to code effectively in short bursts rather than needing extended timelines.

Watch for Compacting Triggers

Claude’s compaction—a memory management routine—signals it's time to wind down a session. I use this occurrence as a cue to pause, record work accomplished, and start afresh if more time remains for that day.

Use GitHub for Protection

Despite solo coding, connecting to GitHub proved invaluable. Creating branches for each new feature ensured I could trial and error safely before consolidating successful code. Regular backups of my dev machine and phone were indispensable safeguards against potential mishaps.

Early Implementation of Data Exchange

Incorporating data import and export mechanisms early on in the application development facilitated smoother testing and debugging phases. This readiness prevented data loss, as it allowed for easy reinstatement after necessary deletions.

Debugging and Problem Solving

Debugging became a collaborative process. By explaining objectives clearly to Claude, like adjusting time-outs for real-world delays in executing app actions, it improved the app's flow and reduced frustration.

Organize Your Project Structure

While Claude might not concern itself with file placement, a well-organized directory structure is crucial for human comprehension and efficiency. Regularly reorganizing and refactoring under guidance maintained clarity and focus throughout development.

Maintain Control and Leadership

At times, Claude might overly direct tasks, offering instructions rather than executing them. Insisting it follows designated roles ensures that you remain in control of the development process.

Leverage Swift and SwiftUI

Utilizing Apple’s native Swift language and SwiftUI framework not only aligns development with iOS standards but lays a foundation for future scalability across Apple devices, such as transitioning an app to macOS with shared code logic.

Final Thoughts

Exploring 'vibe coding' with Claude was enlightening. The value of incremental progress, comprehensive documentation, and command over the development process cannot be overstated. If embarking on similar projects, these lessons are critical to facilitating a smoother, more adaptable experience.
