如何在 xcode 的 Playground 中导入 RxSwift？

How to import RxSwift in Playground of xcode?

提问by Istiak Morsalin

I am trying to import rxswift in xcode playground by this:

我正在尝试通过以下方式在 xcode 操场中导入 rxswift：

gem install cocoapods-playgrounds

and after that

在那之后

pod playgrounds RxSwift

But it is not happening. How to do it?

但它并没有发生。怎么做？

1. You should clone the RxSwift repositoryon your computer
2. Open Rx.xcworkspace
3. Build the RxSwift-macOSscheme
4. Open Rx.playgroundin the Rx.xcworkspacetree view and add a new page
5. import RxSwiftin the new page.
6. Choose View > Debug Area > Show Debug Area

1. 您应该在您的计算机上克隆RxSwift 存储库
2. 打开 Rx.xcworkspace
3. 构建RxSwift-macOS方案
4. Rx.playground在Rx.xcworkspace树视图中打开并添加一个新页面
5. import RxSwift在新页面中。
6. 选择 View > Debug Area > Show Debug Area

it's super easy:

这非常简单：

1. Create a new project, Xcode menu > File > New > Project… (Single View App)
   2. Close Xcode
   3. Initialize pods in the new project (pod init in terminal)
   4. Edit Podfile, add RxSwift, RxCocoa
   5. Install pods (pod install in terminal)
   6. Open RxSwiftProject.xcworkspace created by CocoaPods
   7. Build and run project using default scheme
   8. Add a new playground, Xcode menu > File > New > Playground…
   9. Select Add to: RxSwiftProject , to add it to the RxSwift workspace
   10. Save it in the workspace folder

1. 创建一个新项目，Xcode菜单>文件>新建>项目...（Single View App）
   2. 关闭 Xcode
   3. 在新项目中初始化 pods（终端中的 pod init）
   4. 编辑 Podfile，添加 RxSwift、RxCocoa
   5. 安装 pods（在终端中安装 pod）
   6. 打开 CocoaPods 创建的 RxSwiftProject.xcworkspace
   7. 使用默认方案构建和运行项目
   8. 添加一个新的playground，Xcode menu > File > New > Playground…
   9. 选择 Add to: RxSwiftProject ，将其添加到 RxSwift 工作区
   10. 将其保存在工作区文件夹中

No longer works in Xcode 9.1

不再适用于 Xcode 9.1

$ pod playgrounds RxSwift,RxCocoa

$ pod playgrounds RxSwift,RxCocoa

gives

给

Errno::ENOENT - No such file or directory @ dir_initialize - /Applications/Xcode.app/Contents/Developer/Library/Xcode/Templates/File Templates/Source/Playground with Platform Choice.xctemplate

@Jason, you need to run following commands:

@Jason，您需要运行以下命令：

$ gem install cocoapods-playgrounds

$ gem install cocoapods-playgrounds

$ pod playgrounds RxSwift,RxCocoa

$ pod playgrounds RxSwift,RxCocoa

and it'll work. The second command opens a workspace with already added pods. Just remember to first build a target and then you can play with your new playground.

它会起作用。第二个命令打开一个已经添加了 pod 的工作区。请记住首先建立一个目标，然后你就可以在你的新操场上玩耍了。

You can create a playground with 3rd party SPM libraries with Arena:

您可以使用Arena使用 3rd 方 SPM 库创建游乐场：

arena https://github.com/finestructure/Gala
  resolving package dependencies
  libraries found: Gala
?  created project in folder 'SPM-Playground'

That should work for RxSwift as well.

这也适用于 RxSwift。

回答by Mete

As @sas has hinted at, you can use Arena.

正如@sas 所暗示的那样，您可以使用Arena。

To be more specific:

One line to install Arena:

一行安装 Arena：

brew install finestructure/tap/arena

One line to create your RxSwift enabled Playground:

一行代码来创建启用 RxSwift 的 Playground：

arena https://github.com/ReactiveX/RxSwift

Results:

结果：

??  Package: https://github.com/ReactiveX/RxSwift @ from(5.1.1)
 Resolving package dependencies ...
 Libraries found: RxSwift, RxCocoa, RxRelay, RxBlocking, RxTest
 Building package dependencies ...
? Created project in folder 'Arena-Playground'

Done! Open Arena-Playgroundand find your Playground (probably called MyPlayground), code there. It may require a click on Product -> Build to get going the first time.

完毕！打开Arena-Playground并找到您的 Playground（可能称为 MyPlayground），在那里编写代码。第一次可能需要单击“产品”->“构建”。

That so easy!

就这么简单！

1. Create playground in your project(of course you need to need to add the dependency of RxSwift)

2. In Xcode project navigation, below the playground file, you will find a folder named source

3. Create this swift file in this folder: https://github.com/ReactiveX/RxSwift/blob/master/Rx.playground/Sources/SupportCode.swift

4. Then enjoy it!

   // example
   
   import RxSwift
   
   playgroundShouldContinueIndefinitely()
   
   example("of") {
   
   let disposeBag = DisposeBag()
   
   Observable.of("", "", "", "")
       .subscribe(onNext: { element in
           print(element)
       })
   }
   

1. 在你的项目中创建 playground（当然你需要添加 RxSwift 的依赖）

2. 在 Xcode 项目导航中，在 playground 文件下方，您会找到一个名为 source 的文件夹

3. 在此文件夹中创建此 swift 文件：https: //github.com/ReactiveX/RxSwift/blob/master/Rx.playground/Sources/SupportCode.swift

4. 那就尽情享受吧！

   // example
   
   import RxSwift
   
   playgroundShouldContinueIndefinitely()
   
   example("of") {
   
   let disposeBag = DisposeBag()
   
   Observable.of("", "", "", "")
       .subscribe(onNext: { element in
           print(element)
       })
   }
