JSON到NSMutableArray在Swift 2.3 iOS 10中停止工作

Question

我有一个代码来消费一个REST服务，但它停止工作后更新到swift 2.3和iOS 10。我在JSON中得到错误到NSMutableArray转换:

  class func getStores(latitude:Float, longitude: Float,  completion : (Array<Store>?, NSError?) -> ()) {
    let latString: String = "(latitude)"
    let lonString: String = "(longitude)"
    var listStores: Array<Store> = []
    let urlFull : String = ConstantHelper.baseURLStore
         Alamofire.request(.GET, urlFull, parameters: ["latitude":latString, "longitude": lonString])
            .responseJSON { response in
                switch response.result {
                case .Success:
                    if let repoJSON = response.result.value {
                        print(repoJSON)
                        let jsonArray = repoJSON as? NSMutableArray
                        for item in jsonArray! {
                            guard let store = Store(json: item as! JSON) else
                            {
                                print("Issue deserializing model")
                                return
                            }
                            listStores.append(store)
                        }
                        completion(listStores, nil)
                    }
                    break
                case .Failure(let error):
                        completion(nil, error)
                    break
                }
        }
}

编辑:

错误是"致命错误:在展开可选值时意外发现nil "

表示变量jsonArray为nil。但是只有在swift 2.3中它是nil。因为json到NSMutableArray的转换不再有效。我需要改变皈依的方式……但如何?

这是repoJSON值

我刚刚用

更新了我的代码

let jsonArray = repoJSON as! NSArray

不是

let jsonArray = repoJSON as? NSMutableArray

效果很好!
