iOS development classroom · Android lessons under development

Learn SwiftUI
on the phone
you’re building for.

Every drill is an iOS screen: tap the line that breaks it, patch one SwiftUI token, and watch the iPhone preview update. Jetpack Compose lessons stay closed while Android Studio is under development.

iOS track · 4 SwiftUI modules

Build the screen. Then explain it.

Start with the view on the phone: state that redraws it, a guard that blocks an empty send, an actor that survives a network handoff, and type that scales with the reader. Android modules are listed below as under development.

Android development lessons (Jetpack Compose state, navigation, and Dynamic Type equivalents) are under development with PhoneCoding Studio for Android. The playable modules on this page are iOS.

State on a screen

0 / 3 steps

Why the classroom is iOS first

The lesson is the screen.

You are learning to build the iPhone app, on the iPhone. Each module is a SwiftUI decision you can finish with a thumb, then see on the preview beside the code.

Principle 01

Read the SwiftUI first

The skill is spotting the line that breaks the screen, before you try to retype the view on a glass keyboard.

Principle 02

Visible cause and effect

Every token patch updates the live phone preview beside the snippet so beginners immediately connect syntax to runtime behavior.

Principle 03

Studio diffs become the next lesson

When the iOS studio ships a SwiftUI change, that hunk is the next drill. Compose lessons wait on the Android studio.
