Simple and clean way to convert JSON string to Object in Swift

Question

I have been searching for days to convert a fairly simple JSON string to an object type in Swift but with no avail.

Here is the code for web service call:

Answer 1

for swift 3/4

extension String {
    func toJSON() -> Any? {
        guard let data = self.data(using: .utf8, allowLossyConversion: false) else { return nil }
        return try? JSONSerialization.jsonObject(with: data, options: .mutableContainers)
    }
}

Example Usage:

 let dict = myString.toJSON() as? [String:AnyObject] // can be any type here
