Cannot call value of non-function type 'String'

I'm trying to pass the ILTItem variable into my ILTViewController, triggered by AppDelegate.swift when the user launches my app via a deeplink.

The code I have errors with:

Cannot call value of non-function type 'String'

on the line where I define

Here's the code I have at the moment:

let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
var ilt = ILT(homeworkID: 1234, title: "History ILT", subject: "History", teacher: "Miss A Smith", teacherCode: "asmith", studentID: 12345, description: "Description....", due: 1450137600, status: "In Progress", hasAttachments: true)
var newVC = ILTViewController()
newVC.ILTitem = ilt

Why could this be? In my ILTViewController class I have:

class ILTViewController: UIViewController {
// accept the incoming ILT struct
var ILTitem: ILT!

IlT Struct Declaration:

struct ILT {
let homeworkID: Int
let title: String
let subject: String
let teacher: String
let teacherCode: String
let studentID: Int
let description: String
let due: Double
let status: String
let hasAttachments: Bool

The error is telling you that you are trying to call a String instead of a method (struct constructor in your case). You've probably declared a String variable named ILT (uppercase) somewhere else and that's why it fails.

Your posted code works fine so the error must be somewhere else in your code.
