🍉 KMP Wizard Template — AGP 9.0.0 Ready

A clean Kotlin Multiplatform (KMP) starter generated with the Kotlin Multiplatform Wizard and then updated to work smoothly with Android Gradle Plugin (AGP) 9.0.0.

Here is a Medium article to explain all changes. Moreover, this repository is published as a GitHub Template — click “Use this template” to create your own project in seconds.

Why this template?

If you’ve ever generated a project from the KMP Wizard and then hit friction upgrading to AGP 9, this template is meant to be the “already-migrated” starting point.

It follows the modern recommendation of having:

• a shared KMP module (for Compose Multiplatform shared UI + shared logic)
• a dedicated Android app module (Android entry point)
• a dedicated iOS app (Xcode entry point)

(Those modules are already present in this repo.)

---

What’s inside?

• Kotlin Multiplatform project targeting Android + iOS
• Compose Multiplatform shared UI in composeApp
• Android entry point in androidApp
• iOS entry point in iosApp
• Gradle Kotlin DSL + version-catalog style dependency management (typical wizard output)
• Updated build setup aligned with AGP 9 / “built-in Kotlin” direction

Repo description: “This repository is created by KMP Wizard but updated to use AGP 9.”

Requirements

• Android Studio recent enough to support modern KMP + AGP 9 tooling
• Xcode (to run the iOS app)
• A JDK compatible with your Android Studio / Gradle / AGP setup

See:

• Kotlin Multiplatform Wizard: https://kmp.jetbrains.com/
• Android KMP Gradle plugin guidance: https://developer.android.com/kotlin/multiplatform/plugin
• AGP 9 release notes: https://developer.android.com/build/releases/agp-9-0-0-release-notes

Getting started

1) Create a new repo from this template

1. Open this GitHub repository.
2. Click Use this template → Create a new repository
3. Clone your new repository locally.

2) Run the Android app

Open the project in Android Studio and run the androidApp configuration.

If you prefer the terminal, the wizard-style README in this repo includes:

./gradlew :composeApp:assembleDebug

Depending on your Android module setup, you may also want to use tasks like: ./gradlew :androidApp:assembleDebug or ./gradlew :androidApp:installDebug. Run ./gradlew tasks to see what’s available in your environment.

3) Run the iOS app

Open iosApp/ in Xcode and press Run.

Notes about AGP 9 + KMP (the “why it works” part)

AGP 9 introduces / solidifies changes that matter for KMP projects, including:

• Built-in Kotlin support on the Android side (reduces reliance on legacy Kotlin Android plugin wiring)
• A dedicated Android KMP library plugin (com.android.kotlin.multiplatform.library) recommended for KMP library modules
• Guidance to keep com.android.application in a separate module from the shared KMP module

This template is structured with those realities in mind.
