*SOLVED* Error writing to IOS file system works on android & editor
Hi all, Ive got a function that downloads json and the tries to save a copy on the device. It works fine on android and in the editor. Can't put my finger on it. Ipad is running IOS 10 and settings in unity are 9 upwards if that adds anything.
Below is the unity code plus the error on xcode.

public string url2;
private string jsonString;
public static loadJSONHome instance;
public GameObject preloader;
void Awake(){
if(instance==null){
instance = this;
}
}
void Start (){
WWW www2 = new WWW(url);
StartCoroutine(WaitForRequest(www2));
// preloader.SetActive(true);
}
IEnumerator WaitForRequest(WWW www2){
yield return www2;
// check for errors
if (www2.error == null)
{
//SAVE JSON FROM ONLINE LOCALLY
jsonString = www2.text;
writeStringToFile(jsonString, "FoodnDrink_Cats.json");
writeListings();
} else {
Debug.Log("WWW2 Error: "+ www2.error);
}
}
void writeListings(){
WWW www3 = new WWW(url2);
StartCoroutine(WaitForRequest2(www3));

Location service updates are not enabled. Check LocationService.status before querying last location.

Help appreciated.
I figured it out with help of a youtube video (posted at the end).
I changed the methods to store in binary data form to get around apple isolation and authorization file issues. This is also a lot cleaner.
Here's the code :
using UnityEngine;
using System.Collections;
using System;
using System.Runtime.Serialization.Formatters.Binary;
using System.IO;
public class loadJSONHome : MonoBehaviour {
public string url;
public string url2;
private string jsonString;
public static loadJSONHome instance;
public GameObject preloader;
void Awake(){
if(instance==null){
instance = this;
}
}
void Start (){
WWW www2 = new WWW(url);
StartCoroutine(WaitForRequest(www2));
preloader.SetActive(true);
}
IEnumerator WaitForRequest(WWW www2){
yield return www2;
// check for errors
if (www2.error == null)
{
//SAVE JSON FROM ONLINE LOCALLY
jsonString = www2.text;
Save(jsonString, "FoodnDrink_Cats.json");
writeListings();
} else {
Debug.Log("WWW2 Error: "+ www2.error);
}
}
void writeListings(){
WWW www3 = new WWW(url2);
StartCoroutine(WaitForRequest2(www3));
}
IEnumerator WaitForRequest2(WWW www3){
yield return www3;
// check for errors
if (www3.error == null)
{
//SAVE JSON FROM ONLINE LOCALLY
jsonString = www3.text;
Save(jsonString, "listings_FoodnDrink.json");
} else {
Debug.Log("WWW3 Error: "+ www3.error);
}
preloader.SetActive(false);
}
public void Save(string json, string filename){
BinaryFormatter bf = new BinaryFormatter();
FileStream file = File.Open(Application.persistentDataPath + "/" +filename, FileMode.Create);
myFile current = new myFile();
current.theFile = json;
bf.Serialize(file, current);
file.Close();
}
public string Load(string filename){
if(File.Exists(Application.persistentDataPath + "/" + filename)){
BinaryFormatter bf = new BinaryFormatter();
FileStream file = File.Open(Application.persistentDataPath + "/" + filename, FileMode.Open);
myFile data = (myFile)bf.Deserialize(file);
file.Close();
string fileinfo = data.theFile;
return fileinfo;
}else{
return null;
}
}
}
[Serializable]
class myFile {
public string theFile;
}

The location services is next to resolve but I think it's down to xcode p.list gps settings
