👋 Hello, team!

I’m exploring KMM library for our separate Android/iOS repos in a e-commerce app. Manual comparison of iOS (which lacks a clean architecture) to gauge shareable code is time-consuming. Is there a smarter, more automated way or recommended tools to know how much code we can realistically share and determine the potential ROI?

Any suggestions or best practices would be super helpful!

Maybe I’m confused on the ask, but as far I’m aware, no there’s tool for such a thing, but I’m confused on what you’re asking for… if you’re looking to make a KMP app/library, none of your shareable code would come from the iOS side. You could potentially salvage some Android code for use across platforms, but that’s still a manual ask of grokking what can be used and refactoring it to KMP.

Maybe think of it this way, in a KMP app you share Kotlin code between platforms. You can still have platform specific code, but that’s not shared across platforms, so you cannot share Swift/ObjC to non-Apple platforms.

If I understand the question, I don't think there would be a purpose-built tool for comparing codebases of different languages/frameworks to find commonalities, but this is a use-case where AI tools like ChatGPT, GitHub Copilot Chat, Cursor, or JetBrains AI Assistant might shine.
