How I Structured My iOS App for Scalability Using Modular Architecture (Full Breakdown)

Hey folks 👋

I recently hit a point in my iOS project where everything felt messy — build times were long, testing was a pain, and working with teammates was starting to feel like a PR minefield.

So I decided to go modular 🧱

I just wrote a breakdown of how I structured my app using modular architecture, with practical steps like:

• Using Swift Package Manager for feature & core modules
• Keeping clean access boundaries with internal/public
• Separating interfaces and injecting dependencies properly
• Avoiding overengineering (because nobody needs a module for one enum 😂)

Here’s the article if you’re facing similar chaos:

Would love to hear how others here are approaching modularity or structuring large apps!
