So, to add file associations, we need to be able to pass both the .properties file and the --file-associations option. At the time of writing this article, the org.jetbrains.compose plugin doesn't provide such a mechanism. There is an open issue on GitHub that describes a possible workaround, which, unfortunately seems to not work on macOS.
GraphQL queries are just HTTP POST queries with a JSON body. They're supported everywhere.
If you want specialized tooling for them, Kotlin and Swift both have great strongly-typed GraphQL libraries.
Apollo publishes libraries for both:

Project mention: SLF4K VS kotlin-logging - a user suggested alternative | libhunt.com/r/solo-studios/SLF4K | 2024-03-18kotlin-logging is a Multiplatform logger for kotlin, whereas SLFK4 is a lightweight wrapper around SLF4J, so it only works on JVM. but if you only need JVM support, SLF4K is very good
Business logic is not only about backend. Apps usually have a lot of client-side logic that can be written once in KMM and used on both platforms. See [1] for a high level architecture diagram.
I'm an iOS dev and I've been using KMM on a couple of projects for more than a year now. It's really a powerfull technology which allows teams to move faster, but there are downsides, for example lack of native Swift interop, though there are opensource tools trying to solve this [2].
