Is it possible to develop a KMM library and app in tandem? I mean is there a workflow where I can make changes to the library, make corresponding changes to the app, and build & run to test? Or must I first publish my library changes (to MavenLocal for example), update dependencies in my app, make my app changes, and only then can I build and test?

You're probably looking for Gradle Composite builds; this feature of Gradle enables you to loosely couple separate Library and App projects with 'dependency substitution'.

The bad news is, this is not yet supported with Kotlin Multiplatform.

[darkmoon_uk]

The good news is, support is implemented and due for Kotlin 1.8.20-Beta. Merry K hristmas!

Thanks for the info @darkmoon_uk. Looking forward to the upcoming changes.

Why not just use regular gradle modules in a monorepo instead?

Thanks @Big Chungus. Do you know of an example of this type of project setup? Specifically, I'm building a KMM (iOS and Android) library that will be published internally for use in apps in our organization, and I'd like to include with it a sample app that links directly to the library (no publishing required) for faster iteration while developing the library.

Nothing special about it. Just regular gradle modules with project() dependencies
