Swift Endless Compiling / Indexing

Swift 不出意外的又坑人了。

今天遇到了一个 Swift 无限卡在 Compiling / Indexing 的问题，这个问题导致的原因最终定位到一个关于类型推断的问题

例如下面这段代码就会导致卡在 Compiling / Indexing

var data = [ [ "price": 1, "name": "a" ],
             [ "price": 1, "name": "a" ],
             [ "price": 1, "name": "a" ],
             [ "price": 1, "name": "a" ],
             [ "price": 1, "name": "a" ],
             [ "price": 1, "name": "a" ],
             [ "price": 1, "name": "a" ],
             [ "price": 1, "name": "a" ],
           ]

所以你帮 Swift 做一下推断即可

var data: [[String: AnyObject]] = [ [ "price": 1, "name": "a" ],
             [ "price": 1, "name": "a" ],
             [ "price": 1, "name": "a" ],
             [ "price": 1, "name": "a" ],
             [ "price": 1, "name": "a" ],
             [ "price": 1, "name": "a" ],
             [ "price": 1, "name": "a" ],
             [ "price": 1, "name": "a" ],
           ]
