Question 1

Evidence-based research into offline-first React Native apps identifies which library as the most mature solution for local-first data with automatic sync?

Accepted Answer

Realm (now Atlas Device SDK)

Answer

Realm (now Atlas Device SDK) provides built-in offline-first storage with automatic cloud sync, and is consistently cited in production case studies as the most capable offline sync solution for React Native.

Question 2

Studies on React Native app store rejection rates show that which category of issue is most frequently cited by Apple's App Review team for React Native apps?

Accepted Answer

Privacy labels not matching actual data collection

Answer

Privacy Nutrition Labels introduced in iOS 14+ require accurate disclosure of all data collected, and mismatches between declared and actual data collection are the leading cause of React Native app rejections.

Question 3

Research comparing React Native and Flutter for enterprise adoption in 2023–2024 shows what primary advantage React Native retains over Flutter?

Accepted Answer

Better native module ecosystem and JavaScript talent pool availability

Answer

React Native benefits from the massive JavaScript/React developer ecosystem, making hiring easier and enabling code sharing with web teams, which is its consistently reported enterprise adoption advantage.

Question 4

Evidence-based localization research for React Native apps recommends which library as the community standard for i18n (internationalization)?

Accepted Answer

i18next with react-i18next

Answer

i18next paired with the react-i18next binding is the most widely adopted i18n solution in React Native community surveys, offering namespace splitting, lazy loading, and pluralization support.

Question 5

A team researches the best practice for error boundary implementation in React Native. What does the evidence show is the correct component-level approach?

Accepted Answer

Place error boundaries at feature/screen level boundaries

Answer

Placing error boundaries at the screen or feature level isolates failures to individual sections without crashing the whole app, and allows graceful fallback UI per feature area.
