'Use of Unresolved Identifier' in Swift

Question

So I have been making an app, and everything has been working great. But today I made a new class like usual and for some reason in this class I can't access Public/Global variable from other classes. All the other classes can, but now when ever I try to make a new class I can't. How would this be fixed?

I am using Swift and Xcode 6.

Working Class:

import UIKit import Foundation import Parse import CoreData  var signedIn = true  class ViewController: UIViewController { 

New Class:

import UIKit  class NewClass: UIViewController {      override func viewDidLoad() {         super.viewDidLoad()          signedIn = false  } 

But on signedIn = false

I get the error:

use of unresolved identifier "signedIn"

Answer 1

One possible issue is that your new class has a different Target or different Targets from the other one.

For example, it might have a testing target while the other one doesn't. For this specific case, you have to include all of your classes in the testing target or none of them.

Once I had this problem after renaming a file. I renamed the file from within Xcode, but afterwards Xcode couldn't find the function in the file. Even a clean rebuild didn't fix the problem, but closing and then re-opening the project got the build to work.
