What is a native app?
A native app is software built for a specific platform using that platform's own programming languages and tools, then compiled and installed to run directly on the device. On iOS, a native app is written in Swift or Objective-C and built with Apple's toolchain, which lets it call the operating system directly and use the full range of device features.
How a native app works
A native iOS app is compiled into a binary that the device runs directly, rather than interpreted inside a browser. Because it runs on the metal of the platform, it can call system APIs for the camera, location, notifications, secure storage, background tasks, and more, and it can keep working offline. The user interface is drawn with the platform's own UI framework, which is why a well-built native app feels consistent with the rest of the system: the same gestures, animations, and controls users already know.
This direct access is the defining trait. A native app does not sit behind a browser's limits. It uses the device the way the platform intends, which is why native apps generally lead on performance and on the polish users expect.
Native versus hybrid and web
A native app contrasts with two alternatives. A web app runs in the browser and reaches any device with one, but works within the browser's constraints. A hybrid app runs web code inside a native container, sharing one codebase across platforms while usually giving up some speed and native feel. Native trades cross-platform reach for the deepest integration and the best performance on the platform it targets.
Why it matters
For iOS specifically, native matters because the App Store and its users expect apps that behave like part of the system. Apple's guidelines discourage submissions that are mostly a website in a wrapper, and a native app sidesteps that concern entirely. If your goal is a real App Store app that feels at home on the device, native is the foundation. AppFlight is built only for native iOS, generating Swift and SwiftUI from a plain-English prompt so the result is a genuine native app, with code you can read and edit.
FAQ
What makes an app native on iOS?
A native iOS app is written in Swift or Objective-C, built with Apple tooling, and compiled to run directly on the device. It calls iOS APIs directly, which a web page wrapped in an app shell does not.
What is the difference between native and hybrid apps?
A native app is built with the platform native language and runs directly on the device. A hybrid app runs web code inside a native container. Hybrid shares one codebase across platforms but usually trades away some performance and native feel.
Do I need to know Swift to make a native iOS app?
Traditionally yes. Tools that generate native code from a prompt let you describe the app instead. AppFlight produces native Swift and SwiftUI from plain English, and you can still read and edit the code.
