How to use array of another view controller class?

Question

I need to use the order array in another class (AddOrderVievContoller.swift class)

class OrderListViewController: UITableViewController {

    var orders: [Order] = []

error message in AddOrderVievContoller.swift class: use of unresolved indentifier 'orders'

if results != nil {
    orders = results as! [Order]
}

well, get hold of of an instance of the OrderListViewController inside your AddOrderVievContoller to get its orders value. — luk2302

How are they related? You should have some callback if the view controller is requesting data from something else and particularly if the response is asynchronous — Wain

Create a global variable:

public var orders = [String]()

place this in-between the modules your importing (import UIKit) and the class definition:

import UIKit

public var orders = [String]()

class OrderListViewController: UITableViewController {


//viewDidLoad, etc. 
}

Then you can access the orders array in different viewControllers as you're currently trying to do.
