無法遍歷數組

我想在解析json時從本地服務器獲取一些數據。在視圖控制器我訪問本地Ruby on Rails的服務器：無法遍歷數組

override func viewDidLoad() { 
    super.viewDidLoad() 

    var url = NSURL(scheme: "http", host: "0.0.0.0:3000", path: "/api/search?query=auto") 
    var request = NSURLRequest(URL: url) 

    let task = NSURLSession.sharedSession().dataTaskWithRequest(request) {(data, response, error) in 
    var data1: NSDictionary = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers, error: nil) as NSDictionary 
     println(data1) 
     println(data1["companies"]) 
     var companies = data1["companies"] as NSArray 
     for company: AnyObject in companies { 
      println(company) 
     } 
    } 
    task.resume() 
}

println(data1)回報：

{ 
    companies = "[{\"alias\":\"02-avtomoyka-tulybaev-r-t\",\"id\":45693},{\"alias\":\"1001-zapchast-internetmagazin-avtotovarov\",\"id\":42621}]"; 
}

隨着println(data1["companies"])，我得到了在控制檯對象數組：

[{"alias":"02-avtomoyka-tulybaev-r-t","id":45693},{"alias":"1001-zapchast-internetmagazin-avtotovarov","id":42621}]

然後，當我試圖遍歷該數組時，應用程序崩潰。我究竟做錯了什麼？它stucks在控制檯中沒有錯誤，但在輪距6

PS (lldb)和EXC_BREAKPOINT(code=EXC_I386_BPT, subcode 0x0)：Xcode中還拋出在for company in companies {字符串編譯器問題Constant 'company' inferred to have type 'AnyObject', which may be unexpected。我該如何處理？

您能否提供錯誤並編輯您的查詢，以便更清楚地理解。 – nikhil84

@ walle84我添加了更多的代碼，希望這有助於。 –

對於該編譯器警告，將您的for循環更改爲'for company：AnyObject in companies {...}' –
