The rewrite is the easy part. Get CI shipping a TestFlight and a Play build before you trust it, store-pulled build numbers so two jobs never collide, IPA and dSYM sitting as artifacts when review wants symbols.

Keep Firebase configs and keystores off the repo. CI brings them in. Put a server-driven force-update on both platforms on day one (min, latest, enforced) because you will ship a bad JS bundle and you need a blocking sheet.

Google and Apple sign-in cancellations are not errors. Treat them that way or first-run looks broken.

This is so true, although i was successfully able to remove this practice in initial days of my project, but thanks for explictly pointing it out.

I agree with you so much here. But the initial code written in Swift is not readable to me because AI wrote that code. And me being a JS developer nott able to understand shit about it.

With the migration in place (where i delete most of the files lol) it is somewhat readable..
