Possible challenges before choosing this path.
iOS Developers depend on Apple tools, operating system changes, App Store policies, and platform updates.
Apps must work across different iPhone models, iPad layouts, screen sizes, and iOS versions.
Releases can be delayed or rejected due to metadata, policy, privacy, permissions, or app behavior issues.
Mobile crashes can affect users directly and require fast diagnosis through logs, crash reports, and device testing.
Swift, SwiftUI, iOS SDKs, app architecture patterns, and Apple APIs continue to evolve.
Flutter and React Native may reduce native iOS hiring in some startups, so native depth and app quality matter.
