Convert NSDictionary to Swift Dictionary

Question

Now I know that when swift compiles it just makes a NSDictionary, but the NSDictionary and Swift dictionaries have different syntax. Is there a way (through a loop or something) to convert a NSDictionary to a swift dictionary of the same type for <key, value>?

OR

Is there a way to convert this to a Swift dictionary instead of NSDictionary?

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

Answer 1

use:

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

Answer 2

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

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
    }
}
