Kotlin collections for SQLDelight file are not importing (KMM)

Question

In my KMM project I'm using SQLdelight. My sample table has a List. Table:

CREATE TABLE profile (
nikName TEXT,
secretKey TEXT,
description TEXT,
tagList TEXT AS List<String>
);

According to documentation I created adapter:

//TODO we cant use comas in this string. Convert to JSON
object ListOfStringsAdapter : ColumnAdapter<List<String>, String> {
    override fun decode(databaseValue: String) =
        if (databaseValue.isEmpty()) {
            listOf()
        } else {
            databaseValue.split(",")
        }

    override fun encode(value: List<String>) = value.joinToString(separator = ",")
}

It compiles and works, but Android Studio marks import and List with red:

Unresolved reference: kotlin

Can I fix this somehow?
