IOS中奇怪的统一错误

Question

I am suffering from a strange bug in my project. It runs in unity perfectly but when I build it for IOS, it does one thing in particular differently. When a user picks up 8 items, I have an input box display these items and what order they selected them in. This works perfectly in unity but doesn't in IOS. Anyone have any suggestions as to why this might be the case. Below are the two appropriate scripts.

using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using System.IO;

public class PickUpItem : MonoBehaviour, IInteractable
{

    //Go back to older version of clavem, find out what broke. 

    public string DisplaySprite;

    public string DisplayImage;

    public static string ItemChoosenOrder;

    public static int counter;

    public static GameObject InventorySlots;

    public static GameObject[] PlayerItems = new GameObject[8];

    public void Interact(DisplayImage currentDisplay)
    {
        ItemPickUp();
    }

    void Start()
    {
        PlayerItems = GameObject.FindGameObjectsWithTag("ChoosenItem");
    }

    void Update()
    {

    }

    public void ItemPickUp()
    {
        InventorySlots = GameObject.Find("Slots");

        counter = 0;

        foreach (Transform slot in InventorySlots.transform)
        {
            if (slot.transform.GetChild(0).GetComponent<Image>().sprite.name == "empty_item")
            {
                slot.transform.GetChild(0).GetComponent<Image>().sprite =
                    Resources.Load<Sprite>("Inventory Items/" + DisplaySprite);
                Destroy(gameObject);
                break;
            }


            if (counter <= 7)
            {

                counter++;

                if (counter >= 7)

Working answer using a List collection and directly linking the order by adding each item to the array corresponding to each inventory slot in the appropriate order.
