## Frequently Asked Questions

### Should I learn native or cross-platform?

Native (Swift/Kotlin) offers more opportunities and deeper platform integration. Cross-platform (React Native, Flutter) is efficient for startups with small teams. Both have strong job markets; choose based on interest.

### Is iOS or Android better for jobs?

Both are equally in demand. iOS developers are slightly higher paid in the US. Android dominates globally. Knowing both makes you extremely valuable. Most startups need at least one of each.

### Do I need to know backend development?

Not required but helpful. Understanding APIs, authentication, and how mobile connects to backend makes you more effective. Many mobile developers learn basic backend for personal projects.

### Is Flutter/React Native replacing native development?

Not replacing, but complementing. Many startups choose cross-platform for efficiency. Companies with mature apps often stick with native for performance. Both skill sets are valuable.
