Access array in another Swift file
I have an array called result that I created in a file that I named ParseJSON.swift that is called from ViewController.swift, but when I want to access the array in a separate file MyView.swift it says "Use results" unresolved identifiers "
Obviously the problem is that MyView.swift does not have access to the items in ParseJSON.swift, but I was wondering what is the typical solution for this?
In ParseJSON.swift:
var results = [Int]()
In MyView.swift:
var rect = DataRectangle<Int>()
rect.data = results << error here

don't know what your code structure is, but in general, if you want to access some variables of one file in another:
Here's how you can do it:
//First file
class ParseJson: NSObject {
var results: NSArray = ["1", "2", "3", "4", "5"]
}
//controller
class MyView: UIViewController {
var copiedArray: NSArray = NSArray()
override func viewDidLoad() {
super.viewDidLoad()
var json: ParseJson = ParseJson() //Create object of ParseJson
copiedArray = json.results //access class variables
}}

Create a separate file named Manager.swift and put this code in it ...
//manager.swift
import Foundation
struct Manager {
static var results = [Int]()
}
Clean up the project by pressing Shift + Command + K.
You can now access and change this variable from any view controller. Here's an example.
//viewController.swift
println(Manager.results)
