var list: List<xyzClass> = listOf()

data class xyzClass(
    var nullableString? = null
)

list.filterNotNull()

it will not filter if nullableString is null.

unfortunately, due to type system constraints, you may need to have a cast here

items.asSequence()
    .filter { it.nullable != null }
    .groupBy { it.nullable as String }

ok that's fair point.
Thanks @Shawn
