Here is some variant:

fun life(i: Array<BooleanArray>) = generateSequence(i) {
    val sz = it.size
    Array(sz) { r -> BooleanArray(sz) { c ->
            val n = (-1..1).sumBy { x -> (-1..1).sumBy { y -> if (it[((c + x) + sz) % sz][((r + y) + sz) % sz]) 1 else 0 } }
            if (it[c][r]) n in 3..4 else n == 3
        }
    }
}
