Hello!
I want to integrate a target into an iOS project using Compose Multiplatform. I am using Kotlin version 1.7.20 (Compose Multiplatform does not allow above), agp version 7.4.0-beta02. In Gradle, I connected iOS target, locked all platform features on the iOS side. To build the ios module I use the command
./gradlew clean ios:iosDeployIPhone13Debug

As a result, I get an error (shortened version), where almost all project files are listed in Source files:
> Task :common:compileKotlinUikitX64 FAILED
e: Compilation failed: null cannot be cast to non-null type org.jetbrains.kotlin.ir.declarations.IrFunction

* Source files: AppDatabase.kt, AppDatabaseImpl.kt, AccountsEntity.kt, AccountsEntityQueries.kt, CategoriesEntity.kt, CategoriesEntityQueries.kt, CurrencyRatesEntity.kt, CurrencyRatesEntityQueries.kt, G....

I found only this issue in Google, which is very similar to my mistake, but in my project I checked that there are no expect functions with default values in any file. At the same time, the files that are listed in the Source files do not contain within themselves the code associated with Compose or expect / actual.

How to fix this error? In which direction should I look?

A note on the Kotlin version: 1.3.0-rc02 allows Kotlin 1.8.0

Try marking all Composable methods as internal. This fixed a similar issue for me.

And what kotlin kotlinCompilerExtensionVersion version should I use for Kotlin 1.8.0?

I try it, thank you

[Landry Norris]

It should work by default if you don’t specify a compiler version.

[Landry Norris]

If you do want to specify a version of the compose compiler, use the new forKotlin(version) method.

[Виталий Перятин]

Could you send me link on new forKotlin(version) method please?
I can't find it
