Appending and Updating in a dictionary having a Dictionary as` Value`

Question

I want to add multiple values in same key of dictionary. I have a Dic of type

 var dic1 = [String:[String:AnyObject]](

 dic1.updateValue(["name": cellName,"phone": Phone], forKey: "XYZ")

By this its updating value of key "XYZ" but I want to add more values in same key "XYZ". Can anyone help me out in this?

you need to add that custom operator to use his += suggestion `func += (inout lhs: [Key: Value], rhs: [Key: Value]) { rhs.forEach{ lhs[$0] = $1 } }` — Leo Dabus, Aug 30 '16 at 18:55
@LeoDabus Can you please help me in this. May be by steps or whatsoever suitable for you — Navjot Singh, Aug 30 '16 at 18:57
This will solve the error += cannot be used with two [String:AnyObject] operands — Leo Dabus, Aug 30 '16 at 18:58
@LeoDabus but I don't you how to use your code. please help me out . — Navjot Singh, Aug 30 '16 at 18:59
just put that at the top level of any of your Swift files in your project — Leo Dabus, Aug 30 '16 at 19:00
@LeoDabus I did what you said but its still updating the values for key "XYZ" instead of adding — Navjot Singh, Aug 30 '16 at 19:07
Please add the actual code with the actual result and the expected one — Leo Dabus, Aug 30 '16 at 19:08

You are updating the whole dictionary and you are supposed to update using the key — Leo Dabus, Aug 30 '16 at 19:23

A simple and elegant solution:-

var mutDictionary = [String: NSMutableDictionary]()

//Initialising your mutDictionary:-
mutDictionary = ["Fighters" : ["First" : ["NAME" : "The Tigress", "Phone" : "2131231231"]]]

//Adding a key-hashabale(or in this case String-NSMutableDictionary) pair.  
//`.updateValue` adds a new parent pair to your mutDictionary if your key value is not present if the key is present then it will update that key's value.
mutDictionary.updateValue(["First" : ["NAME" : "Uruguay", "Phone" : "903192301293"]], forKey: "The Bosses")
mutDictionary.updateValue(["FirstOfHisKind" : ["NAME" : "Panda", "Phone" : "123454362"]], forKey: "The Dragon Warrior")    

//Appending data to your mutDictionary:-
mutDictionary["Fighters"]?.setObject(["NAME" : "Guru Shifu", "Phone" : "121212121212"], forKey: "Second")

 print(mutDictionary)

The output that you get from this is something like this :-

   ["Fighters"          : { Second = {  NAME = Guru Shifu; 
                                        Phone = 121212121212;};
                            First = {  NAME = The Tigress;  
                                       Phone = 2131231231;};
                              },
    "The Bosses"        : {First = { NAME = Uruguay;
                                     Phone = 903192301293;};
                              },
    "The Dragon Warrior": {First = { NAME = Panda;
                                     Phone = 123454362;};
                            }]

Thanks a lot buddy. Its not exactly what I want but gave me an idea and I got the desirable output. I am uploading it as a answer — Navjot Singh, Aug 31 '16 at 05:30

can you help me in sorting this array "mutDictionary" by key "name" — Navjot Singh, Aug 31 '16 at 07:26
This is a different question entirely. Avoid building up questions in comments, search net for them, if you dont find any solution ask a well asked question on SO. — Dravidian, Aug 31 '16 at 07:36

Do you mean like this?

var value = Dict1["XYZ"]
value["address"] = "AAA BBB CCC 1234"
Dict1["XYZ"] = value

If I have understood the question:

1) you have to define a class and you can put many values inside it. Example:

 var user_location, user_mail, user_name, user_pass, user_urlPicture: String!

init(user_location: String!, user_mail: String!, user_name: String!, user_pass: String!, user_urlPicture: String!){

    self.user_location = user_location
    self.user_mail = user_mail
    self.user_name = user_name
    self.user_pass = user_pass
    self.user_urlPicture = user_urlPicture

}
// DictionaryConvertible protocol methods
required convenience init?(dict: [String:AnyObject]) {
    guard let user_location = dict["user_location"] as? String, user_mail = dict["user_mail"] as? String, user_name = dict["user_name"] as? String, user_pass = dict["user_pass"] as? String, user_urlPicture = dict["user_urlPicture"] as? String else {
        return nil
    }
    self.init(user_location: user_location, user_mail: user_mail, user_name: user_name, user_pass: user_pass, user_urlPicture: user_urlPicture)
}
var dict:[String:AnyObject] {
    return [
        "user_location": user_location,
        "user_mail": user_mail,
        "user_name": user_name,
        "user_pass": user_pass,
        "user_urlPicture": user_urlPicture
    ]
}

2) In your ("User") class you can add your values:

let user = User(yourLocation, user_mail: yourMail, user_name: yourName, user_pass: yourPass, user_urlPicture: yourUrlPicture)

        var mutDictionary = [String: NSMutableDictionary]()
        let keyVar = String(cellName[cellName.startIndex])
        if mutDictionary[keyVar] == nil {
          mutDictionary.updateValue([:], forKey: keyVar)
          mutDictionary[keyVar]?.setObject(["Name" : cellName, "Phone" : Phone], forKey: cellName)
        }
        else{
          mutDictionary[keyVar]?.setObject(["Name" : cellName, "Phone" : Phone], forKey: cellName)
        }
    print(mutDictionary)
