String to JSON Object Convert iOS Swift

Question

From the Server, I am receiving the below string as (AnyHashable : String)

{Type:1, OrderId:174}

I know it is not a valid Json String, but I have to deal with Type and OrderId separately

I am converting a string to JSONObject but as my string is invalid, therefore below code not converting it.

if let tag = notification.request.content.userInfo["tag"]{
        if let json = try? JSONSerialization.data(withJSONObject: tag, options: []) {
            // here `json` is your JSON data
            print(json)
        }
    }

Anyone can suggest what should I do to get Type and OrderId value so I can handle the response? Or I have to convert string to json and then convert to JSONObject?

The server response is not valid JSON.

Since the string is not valid JSON you have to convert it manually.

The code

Removes the leading and trailing braces.
Splits the string by ", ".
Converts each item to [String:Int].

It assumes that all keys are String and all values are Int

let string = "{Type:1, OrderId:174}"
let trimmedString = string.trimmingCharacters(in: CharacterSet(charactersIn: "{}"))
let components = trimmedString.components(separatedBy: ", ")
var result = [String:Int]()
_ = components.map { item in
    let keyValue = item.components(separatedBy: ":")
    result[keyValue[0]] = Int(keyValue[1])
}

Console:

["Type": 1, "OrderId": 174]

Thanks, man, I changed the code little bit for my requirements. Now the result can be ended/decoded in JSON.
