A step-by-step tutorial on building a cross-platform mobile app for iOS and Android using Compose Multiplatform and Kotlin.

Compose Multiplatform for iOS is currently in Alpha, so now is a great time to explore the technology: Let’s build a simple app from start to finish in Kotlin. In the process, you’ll see how Compose Multiplatform and Kotlin Multiplatform enable sharing everything - from the networking layer, to business logic, to UI. The end result will be a small app that can load and display different bird pictures from an API, that will run on both Android and iOS!
