I always get this error when rebuild room in ios:

Task :composeApp:compileCommonMainKotlinMetadata FAILED
e: file:///Users/mohdhafiz/StudioProjects/katmaans_mobile_frontend/composeApp/src/commonMain/kotlin/com/kloudius/katmaans/data/db/AppDatabase.kt:23:8 Object 'AppDatabaseConstructor' is not abstract and does not implement abstract member 'initialize'.

sample code

// The Room compiler generates the `actual` implementations.
@Suppress("NO_ACTUAL_FOR_EXPECT")
expect object AppDatabaseConstructor : RoomDatabaseConstructor<AppDatabase>

Event upgrade library room also the same and running ./gradlew build failed because of this.

does it work on Android? in my case I had to override initialize like this

expect object AppDatabaseConstructor : RoomDatabaseConstructor<AppDatabase> {
    override fun initialize(): AppDatabase
}

@Giorgi it does work in android and ios only things that above error happen when do ./gradlew build

hard to say what is really wrong. Have you seen Fruities sample https://github.com/android/kotlin-multiplatform-samples/tree/main/Fruitties? it uses Room and you could compare your implementation to theirs

[hafiz]

@Giorgi still the same :
@Database(entities = [Fruittie::class], version = 1)
@ConstructedBy(AppDatabaseConstructor::class)
abstract class AppDatabase : RoomDatabase() {
abstract fun fruittieDao(): FruittieDao
}

// The Room compiler generates the actual implementations.
@Suppress("NO_ACTUAL_FOR_EXPECT")
expect object AppDatabaseConstructor : RoomDatabaseConstructor<AppDatabase> {
override fun initialize(): AppDatabase
}
