Swift- using the array in different classes

Question

I have two classes both for different UIViewController, in one of the classes i have 3 arrays, and i have added those arrays to a NSUserdefaults, now i want to call those/use those arrays in the other class, how do i do that?

let userDefaults = NSUserDefaults.standardUserDefaults()
    userDefaults.setObject(name, forKey: "ThisContainsName")
    userDefaults.setObject(surname, forKey: "ThisContainsSurname")
    userDefaults.setObject(money, forKey: "ThisContainsBudget")
    userDefaults.synchronize()

What's wrong with let xyzObjects = userDefaults.arrayForKey("xyz")? — BaseZen

Just use arrayForKey to get the arrays:

var yourNames =  NSUserDefaults.standardUserDefaults().arrayForKey("ThisContainsName")   
var yourSurnames =  NSUserDefaults.standardUserDefaults().arrayForKey("ThisContainsSurname") 
var yourMoneys =  NSUserDefaults.standardUserDefaults().arrayForKey("ThisContainsBudget")

If i do this way to get the arrays, suppose in my table view cell i wasn't to se the text equal to the string in the array should i do this way? But i doubt it will work since yourNames is just a variable. cell.textLabel?.text = yourNames[0]

It should work exactly that way you mentioned. Just try yourNames[0].

when i do that i get an error saying [AnyObject]? doesn't have a member names 'subscript' if(names?.isEmpty == false ){ return cell.textLabel?.text = names[0] }

you need to cast your array to stringarray: NSUserDefaults.standardUserDefaults().arrayForKey("ThisContainsName") as [String]

i tried as well, still gives me the same errors message. but this time it says [String]? doesn't have a member names 'subscript'
