Hi everyone, What is the type safe way to extract list of specific data type in given position from

Array<Any?>

?

fun main() {
    val x: Array<Any?> = arrayOf(listOf(1, 2, 3), listOf('a', 'b', 'c'))
    val y = x[0] as? List<Int> ?: emptyList()
    val z = x[1] as? List<Char> ?: emptyList()
    y.forEach {
        println(it)
    }
    z.forEach {
        println(it)
    }
}

y

has

Unchecked cast: Any? to List<Int>

and

z

has

Unchecked cast: Any? to List<Char>

. How to fix this properly?
