I’ve built a small Amazon Price Tracker app in React Native. The app is fairly lightweight and not CPU-intensive:
Uses React Navigation
Screens:
Home Screen → lists tracked products
Item Edit Screen → shows product details + price history chart
Deals Screen → lists available deals
All processing happens on the server
API calls are async
No heavy local computation
App has been live on Android for ~1 year without issues
Problem (iOS only):
On iOS devices:
Initial load works perfectly
After a few navigations between screens:
Some screens don’t render at all
Some screens partially render
UI becomes inconsistent/unpredictable
Android has zero issues
This happens on real devices, not just the simulator.
I’ve searched Google, StackOverflow, and Reddit but couldn’t find a clear solution.
Question:
What are the most common causes of this behavior on iOS in React Native apps?
What are the best practices to prevent iOS screens from failing to render after navigation?
Specifically looking for:
iOS-specific rendering pitfalls
React Navigation lifecycle issues
memory/view recycling problems
known RN + iOS rendering constraints
production-grade best practices for stability
