IOS Serialization How To

I have the following code and t$$anonymous$$s works on all platforms except iOS, does anyone know how I can get the list of classes stored in iOS in a similar fas$$anonymous$$on as below?

 using UnityEngine;
 using System.Collections;
 using System.Collections.Generic;
 using System.IO;
 using System.Linq;
 using System.Runtime.Serialization.Formatters.Binary;
 using System.Runtime.Serialization;
 
 public class SettingsControl : MonoBehaviour {
     
     public static SettingsControl control;
     
     [System.Serializable]
     public class Setting{
         public string Language;
         public string defaultlanguage;
         public string Omschrijving;
         public string Actievoor;
         public string Zoeken;
         public string NoDesription;
         public string panel2;
         public string panel3;
         public string panel4;
         public string panel5;
         public string disclaimer;
         public string twoagree;
 
     }
 
     [System.Serializable]
     public class ListContainer
     {
         public List<Setting> settings; 
     }
     
     public List<Setting> settings=new List<Setting>();
     
     void Awake () {
         // there can be only ONE ! across scenes
         if (control == null)
         {
             DontDestroyOnLoad(gameObject);
             control = t$$anonymous$$s; 
         }
         else if(control != t$$anonymous$$s)
         {
             Destroy(gameObject);
         }
     }
 
     public bool FirstTime()
     {

         //UnitySerializer.SerializeToFile (lc.settings,Application.persistentDataPath + "/SettingsData.dat");
         // Write Data
         bf.Serialize(file,lc.settings);
 
         file.Close ();
     }

         }
         else

         }

         foreach (Setting s in settings)
         {
             s.defaultlanguage = sSelectedLanguage;
         }
         //(from s in settings where s.defaultlanguage == "*" select s).First().defaultlanguage = sSelectedLanguage;
