游乐场导入:没有此类模块“Foo”

时间:2022-05-11 16:56:20

I've diligently followed the Apple instructions to import a custom module into a playground, including the instructions here. And yet I get:

我认真地按照苹果的说明将一个自定义模块导入到一个游乐场,包括这里的说明。然而我得到:

Playground execution failed: /var/folders/z3/kd0nj4ln1rgcpm8bdz7067wh0000gs/T/./lldb/1874/playground1.swift:7:8: error: no such module 'Foo' import Foo

操场上执行失败:/var/folders/z3/kd0nj4ln1rgcpm8bdz7067wh0000gs / T /。/ / 1874 / playground1 lldb。错误:没有这样的模块‘Foo’导入Foo

How can I recover to a working Playground import? [Edit: Note, two answers have produced detailed instructions to associate a playground with a framework; I have followed those instructions but no luck. The solution will need to involve reconfiguring something in Xcode; my installation is apparently broken]

如何恢复到可工作的游乐场入口?[编辑:注意,有两个答案给出了详细的说明,将操场与框架联系起来;我遵从了这些指示,但没有成功。解决方案将需要重新配置Xcode中的某些内容;我的装置显然坏了]

For some of those that none of the above solutions work (and that Xcode build path setting was already set to Unique), I've found a solution.

对于上述解决方案中任何一个都不起作用的一些解决方案(Xcode构建路径设置已经设置为Unique),我找到了一个解决方案。

The framework must be built with a scheme for an iOS simulator device (any in the list) and NOT a Generic iOS Device, as Playgrounds do not support it. This one worked for me :

这个框架必须建立在一个iOS模拟器设备(列表中的任何一个)的方案中,而不是一个通用的iOS设备,因为操场不支持它。这个对我很有用:

Here's how I proceed for OS X with Xcode 7.1:

以下是我如何用Xcode 7.1操作OS X:

  • Create new project: OS X Cocoa Framework, Swift. For this example I named it "TestPlaygroundFMK".

    创建新项目:OS X Cocoa框架,Swift。对于这个示例,我将它命名为“TestPlaygroundFMK”。

  • Create a new Swift file.

    创建一个新的Swift文件。

  • Add a class to the file. The code has to be public. I made this for our example:

    向文件添加类。代码必须是公共的。我做这个是为了我们的例子:

import Foundation

public class Talk {
    public class func sayHello() {
        print("Hello from framework!")
    }
}
  • Build the project now.

    现在构建项目。

  • In the menu bar, click on File > Save As Workspace.

    在菜单栏中,单击File > Save As Workspace。

  • Create a new Playground and save it inside the project folder next to the Swift files.

    创建一个新的运动场,并将它保存在Swift文件旁边的项目文件夹中。

游乐场导入:没有此类模块“Foo”

The Playground must not have the same name as the project.

运动场不能和项目同名。

  • Build the project again.

    构建项目。

  • Import your framework in the Playground and use it:

    在操场上导入你的框架并使用它:

import TestPlaygroundFMK

Talk.sayHello()

游乐场导入:没有此类模块“Foo”

  1. Create a workspace as below:

    创建如下所示的工作区:

    • Choose File > New > Workspace
    • 选择File >新的>工作区
    • Enter the workspace name, and specify its location in your file system
    • 输入工作区名称,并在文件系统中指定其位置
    • Click Save
    • 点击保存
  2. Now, Create a Cocoa framework with swift file which have your class

    现在,使用包含类的swift文件创建一个Cocoa框架

    • Choose File > New > Project
    • 选择文件>新的>项目
    • Select Cocoa framework > Next
    • 接下来选择Cocoa framework >
    • Enter Product Name and Language > Next
    • 接下来输入产品名称和语言>
    • Before clicking create, in 'Add to:' and 'Group' list choose 'Your workspace name' as shown 游乐场导入:没有此类模块“Foo”
    • 在单击create之前,在“Add to:”和“Group”列表中选择“您的工作区名称”。
    • Framework is added to your workspace
    • 框架被添加到您的工作区中
  3. Create swift file in your framework
    • In Xcode right click on the folder where you want to add swift file and select new file...
    • 在Xcode中,右键单击要添加swift文件的文件夹并选择new file…
    • Select swift > Next > Name your file > Create
    • 选择swift >下一个>名称创建您的文件>
  4. 在您的框架中创建swift文件,在Xcode中右键单击要添加swift文件的文件夹,并选择新文件…选择swift >下一个>名称创建您的文件>
  5. Select your framework in Xcode -> Build your framework
  6. 在Xcode中选择您的框架——>构建您的框架
  7. Create playground -> Playground should also be part of your workspace, if not drag it to your workspace, it'll be added automatically.
    • Right click in Xcode's files section > New file... > Playground
    • 右键点击Xcode's files section > New file…>操场
    • import
    • 进口
    • Call your method
    • 打电话给你的方法
  8. 创建游乐场->游乐场也应该是你的工作空间的一部分,如果不把它拖到你的工作空间中,它会自动添加。右键点击Xcode's files section > New file…调用你的方法

Note: If you just wanted to add classes instead of framework to your playground check the link How to import my own class into an Xcode 7 playground?

注意:如果你只是想添加类而不是框架到你的操场,检查链接如何将我自己的类导入到Xcode 7的操场上?

I had my playground working fine but found that when I quit Xcode and re-opened it, I would get an error like this:

我的游乐场运行得很好,但当我退出Xcode重新打开它时,我发现会出现如下错误:

error: /var/folders/ft/bmk8wh6s5ms4my2pxhn3qbp40000gn/T/playground1-9216e0..swift:3:8: error: no such module 'Playground_Sources' import Playground_Sources

错误:/var/folders/ft/bmk8wh6s5ms4my2pxhn3qbp40000gn / T / playground1 - 9216 e0 . .错误:没有这样的模块“Playground_Sources”导入Playground_Sources

... where "Playground" is the name of my playground file.

…“游乐场”是我的游乐场文件的名字。

The solution to this (in Xcode 9.0) is to:

这个(Xcode 9.0)的解决方案是:

  • click any playground file in your workspace
  • 单击工作区中的任何游乐场文件
  • show the Utilities panel (opt-cmd-0)
  • 显示实用程序面板(opt-cmd-0)
  • under "Playground Settings" change the "Platform" to anything else then set it back.
  • 在“操场设置”下,将“平台”更改为任何其他设置,然后将其设置为后退。

In my case, it's set to macOS. I changed it to iOS then back to macOS (no recompilation necessary) and it started to work fine... that is until I close Xcode and open it again.

在我的例子中,它被设置为macOS。我把它改成了iOS,然后又改成了macOS(不需要重新编译),它开始运行得很好……直到我关闭Xcode并再次打开它。

This is the only solution I found to work with macOS playgrounds. This bug still exists in Xcode 9.3.

这是我在macOS操场上找到的唯一解决方案。这个错误仍然存在于Xcode 9.3中。

The solution, from Apple Support, was to adjust my Xcode Preferences. On Locations :: Advanced my configuration was 'Legacy'. By changing to 'Unique', and undoing any paths I'd attempted to insert, Playgrounds can now import frameworks.

苹果支持的解决方案是调整我的Xcode首选项。位置:高级配置为“遗留”。通过更改为“Unique”,并取消我试图插入的任何路径,Playgrounds现在可以导入框架。

I don't think it's a stretch to say that Xcode is somewhat of a blackbox. I make no claim that this will work for anyone else, but for me, after having the same issue after creating a new playground and a new framework target, and all the other proposed solutions, what finally worked was deleting the workspace file and (in my case) regenerating it with cocoapods.

我不认为Xcode有点像黑盒子。我没有声称这将为其他人工作,但对我来说,在同样的问题后,创建一个新操场和一个新的框架目标,和所有其他的提出解决方案,最后是删除工作区文件工作,(对于我来说)与cocoapods再生。

I have no idea why this worked.

我不知道为什么会这样。
