如何将自己的课程导入Xcode 7游乐场? [英] How to import my own class into an Xcode 7 playground?

问题描述

我知道之前曾问过这个问题，但是我没有找到有关Xcode 7和Swift 2的答案.许多答案只是模棱两可，不正确或过时.

I know this question was asked before, but I didn't find an answer in relation to Xcode 7 and Swift 2. Many answers are just ambiguous, incorrect or outdated.

是否有将单个班级或一组班级导入操场的明确方法?

Is there a clear way to import a single class or a set of classes to a playground?

推荐答案

在操场上转到菜单

查看/导航器/显示项目导航器

View / Navigators / Show Project Navigator

并将您的课程文件复制到Sources文件夹中.

and copy your class files into the Sources folder.

您的班级必须这样标记为public:

Your classes have to be marked public like this:

public class MyPlayGround {
    public class func sayHello() {
        print("Hello")
    }
}

然后，游乐场可以访问课程:

The Playground will then have access to the classes:

MyPlayGround.sayHello()
