# multiplatform

[Russell Stewart]

Are there any good guides/tutorials on transitioning a KMP app with Native UI (Jetpack Compose and SwiftUI) into using Compose Multiplatform? That is, if I have a large and functional KMP codebase that uses Compose and SwiftUI to build targets for Android and iOS, convert that into a codebase that keeps the same shared code and uses CMP on both platforms - preferably without having to start a new project from scratch.

Just to be clear, it's not the CMP itself I need help with. I've been working with it for a little while, and I think I can handle the transition from Android-only Compose to CMP. I'm more concerned about the structure of the project, the build files, etc.

If you are looking to fully migrate to CMP, that may end up being a fully new app on the iOS side. Is that what you are after?

If you are interested in keeping your iOS Native UI in Swift and sharing the business logic, I can share some extensive guidance we are working on (not yet published). It would be good to get your feedback. Let me know.

I'm already using Compose and SwiftUI with shared business logic in Kotlin. What I'm interested in is transitioning the codebase to a full Compose Multiplatform app (using Swift code where necessary, of course).

[Russell Stewart]

I know this will require some changes to the Compose code, like updating references to String resources, and that's tedious but I can handle it. I also know there will be some platform-specific UI that I'll have to pull out, and that's fine too. My main concern is the build files and the overall structure of the codebase; I don't know how difficult it will be to make that transition.

Could you create a new project using the wizard and compare the gradle-related files?

[Russell Stewart]

Yeah, that's a good idea
