The function you're looking for is called toList():

val set: Set<Int> = setOf(1,2,3)
val list: List<Int> = set.toList()

Wow! Why is it sometimes "as" and sometimes "to"?! – Dims Mar 11 '18 at 21:42

`as` most often implies that the object is being reused in the created instance. Take `asList` and `toList` for arrays as an example: https://stackoverflow.com/questions/48411392/how-are-kotlin-arrays-tolist-and-aslist-different/48411459#48411459 – s1m0nw1 Mar 11 '18 at 21:44
