Deevaa - Building Apps, Connecting People

Introduction

So far we've built shared UI and run it on Desktop + Android. Now let's take the same code to iOS.

Step 1: Create ViewController in iosMain

MainViewController.kt (iosMain)kotlin

1fun MainViewController() = ComposeUIViewController {
2    QuotesScreen()
3}

Step 2: Hook into Swift

In iosApp:

ContentView.swiftswift

1struct ContentView: UIViewControllerRepresentable {
2    func makeUIViewController(context: Context) -> UIViewController {
3        MainViewController()
4    }
5    func updateUIViewController(_ uiViewController: UIViewController, context: Context) {}
6}

Step 3: Run in Simulator

Quick Tip: Select iosApp run config in IntelliJ, or open in Xcode.

▶ Run → your app launches in iOS Simulator with the same UI.
