Cannot convert value of type 'NSDictionary' to specified type 'Dictionary'

Why is this possible: 

var orderRequestUserValues : Dictionary  = [ "ClientID": "TEST",
                                                 "UserName": "sysadmin",
                                                 "Password": "123456",
                                                 "ModuleID": "StockProcessing",
                                                 "FunctionID": "SetStockActivity",
                                                 "TransmissionFlags": 32,
                                                 "TransmissionMethod": 5
    ]

But this is not:

let userName : String = (dataSourceForUserInfo.last?.UserName)!
let password : String = (dataSourceForUserInfo.last?.Password)!
let clientID : String = (dataSourceForUserInfo.last?.ClientID)!
var orderRequestUserValues : Dictionary  = [  "ClientID": "\(clientID)",
                                              "UserName": "\(userName)",
                                              "Password": "\(password)",
                                              "ModuleID": "StockProcessing",
                                              "FunctionID": "SetStockOrder",
                                              "TransmissionFlags": 32,
                                              "TransmissionMethod": 5


    ]

Getting error :Cannot convert value of type 'NSDictionary' to specified type 'Dictionary'

I need it to work like this because I have to append data to it like so: 

orderRequestUserValues.updateValue(requestParameters, forKey: "RequestParameters")

This should be what you want

var orderRequestUserValues : [String : Any]  = [
    "ClientID": "TEST",
    "UserName": "sysadmin",
    "Password": "123456",
    "ModuleID": "StockProcessing",
    "FunctionID": "SetStockActivity",
    "TransmissionFlags": 32,
    "TransmissionMethod": 5
]

And this works too with string interpolation: 

var orderRequestUserValues : [String : Any]  = [
    "ClientID": "\(clientID)",
    "UserName": "\(userName)",
    "Password": "\(password)",
    "ModuleID": "StockProcessing",
    "FunctionID": "SetStockOrder",
    "TransmissionFlags": 32,
    "TransmissionMethod": 5
]

And also notice that you can use let instead of var if the dictionary is immutable.

Can't we write NSDictionary instead of Dictionary. It works too.

We need to stop using NSDictionary in swift? where Dictionary is native for Swift struct

 let orderRequestUserValues : NSDictionary  = ["ClientID": "\(clientID)",
                                                  "UserName": "\(userName)",
                                                  "Password": "\(password)",
                                                  "ModuleID": "StockProcessing",
                                                  "FunctionID": "SetStockOrder",
                                                  "TransmissionFlags": 32,
                                                  "TransmissionMethod": 5]


    let name = orderRequestUserValues.object(forKey: "Username")
    print(name)

For swift2 or swift3 you need to specify the type of key and value for dictionary. So use the below code-

        let userName : String = (dataSourceForUserInfo.last?.UserName)!
        let password : String = (dataSourceForUserInfo.last?.Password)!
        let clientID : String = (dataSourceForUserInfo.last?.ClientID)!
        let orderRequestUserValues : Dictionary  = [  "ClientID": "\(clientID)",
                                                      "UserName": "\(userName)",
                                                      "Password": "\(password)",
                                                      "ModuleID": "StockProcessing",
                                                      "FunctionID": "SetStockOrder",
                                                      "TransmissionFlags": 32,
                                                      "TransmissionMethod": 5


            ] as [String : Any]
