swift2 - Playground Xcode : Failed to obtain sandbox extension

Question

我在 IOS9 xcode 项目中的 .playground 文件中有此错误消息:

2015-10-28 16:28:45.159 Playground[83944:17501939] Failed to obtain sandbox extension for path=/var/folders/h7/cbc1x51x2rs7sjzfk0ndtxkr0000gp/T/com.apple.dt.Xcode.pg/containers/

我所做的是:

启动了 Xcode 7/Swift 2 项目

使用“pod install Alamofire”

使用以下代码创建了一个 .playground 文件:

进口 Alamofire

Alamofire.request(.GET, "http://httpbin.org/get" , parameters: ["foo": "bar"]).responseJSON { response in

        print(response.request)  // original URL request
        print(response.response) // URL response
        print(response.data)     // server data
        print(response.result)   // result of response serialization

        let str = response.data!

        if let JSON = response.result.value {
            print("JSON: \(JSON)")
        }
}

如何在 .playground 文件中测试这个库而不会出错？

Answer 1

根据所有者的说法，从版本 3 开始，似乎已经取消了对操场的支持:

We removed the playground in the latest versions of Alamofire. Caused more problems than it was worth.

不幸的是，要启用 Playground 支持，您必须降级 Alamofire。
