Swift is Apple's own language for iOS, iPadOS, and macOS, the choice when an app needs to go deeper than a cross-platform framework reaches: the latest OS APIs on day one, tight performance on device-intensive work, or a native feel that cross-platform tooling can't quite match. It's a different tool than React Native or Flutter, not a better or worse one, chosen when the project specifically calls for native-only.
We build the same way regardless of language or role: you tell us what's actually slowing you down, we tell you what's realistic, and we stay around after it ships.
