Hi i was searching for these I have the same issue recursiveFetchLongSparseArray for 2.7.0 alpha03 and under :


```
    @Transaction
    @Query("SELECT * FROM person_local WHERE uid = :uid")
    fun getPersonWithFilesByUid(uid: Long): Flow<PeopleWithFiles>
```
```
import androidx.room.Embedded
import androidx.room.Relation

data class PeopleWithFiles(
    @Embedded val person: Person,
    @Relation(
        parentColumn = "uid",
        entityColumn = "personUid"
    )
    val filesEntity: List<PeopleFileEntity> = emptyList()
) {
    fun toFilePaths(): List<String> {
        return filesEntity.map { it.filePath }
    }
}
```

```
import androidx.room.ColumnInfo
import androidx.room.Entity
import androidx.room.ForeignKey
import androidx.room.Index
import androidx.room.PrimaryKey

@Entity(
    tableName = "person_local_files",
    foreignKeys = [
        ForeignKey(
            entity = Person::class,
            parentColumns = ["uid"],
            childColumns = ["personUid"],
            onDelete = ForeignKey.CASCADE
        )
    ],
    indices = [Index(value = ["personUid"])] // Add this line
)

data class PeopleFileEntity(
    @PrimaryKey(autoGenerate = true) val fileId: Long = 0,
    @ColumnInfo(name = "personUid") val personUid: Long,
    @ColumnInfo(name = "filePath") val filePath: String,
    @ColumnInfo(name = "fileTag") val fileTag: String
)
```

I attach the builded file

I'm also having the same issue, I have a similar setup to https://issuetracker.google.com/issues/341002184#comment6

I don't see an ios/native impl for this method. Not sure if that'll help fix this bug

Thank you!

I am looking to make use of room asap. When can we expect the next release of Room?

    Resolve invalid Relation codegen.
   
    Users were encountering a "missing recursiveFetchLongSparseArray()" error in
    codegen for iOS. This issue was due to the fact that room-runtime was not
    depending on androidx.collection in common. Now that androidx.collection is
    available in KMP (and, therefore, LongSparseArray is available) we can
    depend on it in room-runtime.
   
    This issue was reproduced and verified by adding the androidx.collection
    dependency to the common source set of the kotlin multiplatform test app
    and using existing tests that use @Relation on the iOS target. Once verified, the
    dependency was added to room-runtime common source sets, and the
    `recursiveFetchLongSparseArray()` function has been moved from the
    Android-only RelationUtil.android.kt to the common RelationUtil.kt.

I have a question it will be release with alpha 05 ?

Do you have a release schedule?
