Question

现在我知道，当swift编译它只是创建一个NSDictionary，但NSDictionary和Swift词典有不同的语法。是否有办法（通过循环或其他方式）将NSDictionary转换为<key, value>的相同类型的快速字典？

OR

有没有办法将其转换为Swift词典而不是NSDictionary？

let jsonDict = NSJSONSerialization.JSONObjectWithData(jsonData, options: nil, error: &error) as NSDictionary

Answer 1

使用：

let jsonDic = NSJSONSerialization.JSONObjectWithData(jsonData, options: NSJSONReadingOptions.MutableContainers, error: &error) as Dictionary<String, AnyObject>;

Answer 2

我从http://www.swift-studies.com/blog/2014/6/6/loading-a-swift-dictionary-from-a-plist-file

找到答案

var swiftDict : Dictionary<String,AnyObject!> = Dictionary<String,AnyObject!>()
for key : AnyObject in ocDictionary.allKeys {
    let stringKey = key as String 
    if let keyValue = ocDictionary.valueForKey(stringKey){
        swiftDict[stringKey] = keyValue
    }
}

Answer 3

NSDictionary和Dictionary几乎可以互换。所以没有必要，但是你可以：

let jsonDict = (NSJSONSerialization.JSONObjectWithData(jsonData, options: nil, error: &error) as NSDictionary) as Dictionary

将NSDictionary转换为Swift Dictionary
