Dictionary [String: String] keys order changed when converted to array swift

I have a dictionary like below,

var dataSource: [String: String] = ["FirstName": "Austin",
                                    "ListName": "Michael",
                                    "Address": "Street Address",
                                    "City": "Chennai"]

I want to populate these values in a UITableView, so I tried to get all the keys from Dictionary to an Array like below,

let dataArray = Array(dataSource.keys)

I got the output as [String] like,

["LastName", "FirstName", "City", "Address"]

The problem is, the order of the keys has changed, I want the array in the same order as dictionary has.

Can you anyone help?

Use plain dictionary as tableview datasource is bad idea.

However Dictionary can not be sorted. So it doesn't matter in what order you add your keys-values to the dictionary.

If you need sorted then use array of dictionary instead.

You should use models instead of plain dictionary that is easy to maintain :]

like 

struct User {

    var firstName:String?
    var lastName:String?
    var address:String?
    var city:String?
}
