Hashsets Unity iOS

Do HashSets work on Unity iOS?

It looks like HashSets work on iOS (not just in editor)

using UnityEngine;
using System.Collections;
using System.Collections.Generic;

public class HashSets : MonoBehaviour {

	string hash;

	void Start(){
		GenHash ();
	}

	void GenHash(){
		hash = "";
		HashSet hashset = new HashSet ();

		for(int i=0;i<100;i++){
			hashset.Add (new Vector2(Random.value,Random.value));
		}

		foreach (Vector2 v in hashset) {
			hash+=v.ToString();
				}
	}

	void OnGUI(){
		GUI.Label (new Rect(5,5,Screen.width,Screen.height),hash);
	}

}
