Swift 中“未解析标识符的使用" [英] 'Use of Unresolved Identifier' in Swift

问题描述

所以我一直在制作一个应用程序，一切都运行良好.但是今天我像往常一样创建了一个新类，出于某种原因，在这个类中我无法从其他类访问公共/全局变量.所有其他课程都可以，但现在每当我尝试创建一个新课程时，我都做不到.这将如何解决?

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?

我使用 Swift 和 Xcode 6.

I am using Swift and Xcode 6.

工薪阶层:

import UIKit
import Foundation
import Parse
import CoreData

var signedIn = true

class ViewController: UIViewController {

新课程:

import UIKit

class NewClass: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        signedIn = false

}

但是在 signedIn = false

我收到错误:

使用未解析的标识符signedIn"

use of unresolved identifier "signedIn"

推荐答案

一个可能的问题是你的新班级有一个不同的 Target 或与另一个不同的 Targets.

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

例如，它可能有一个测试目标，而另一个没有.对于这种特定情况，您必须将所有类都包含在测试目标中，或者不包含任何类.

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.
