Extract Data out of JSON in swift - json

Question

This question has been asked a hundred times, but the internet isn't helping, mostly because I am new to swift and programming, so my apologies in advance.
I am trying to extract some data out json.
Here is my code:
let request = NSMutableURLRequest(url:myUrl! as URL);
request.httpMethod = "POST";
let postString = "email=\(email)";
request.httpBody = postString.data(using: String.Encoding.utf8);
let task = URLSession.shared.dataTask(with: request as URLRequest){
data, response, error in
if error != nil {
print("error=\(error)")
return
}
var err: NSError?
do
{
let myJson = try JSONSerialization.jsonObject(with: data!, options: JSONSerialization.ReadingOptions.mutableContainers) as AnyObject
print(myJson)
let name = myJson["name"]
}
catch let error as NSError {
err = error
}
}
task.resume()
And here is the JSON out of print(myJson):
(
{
name = "TestTest";
}
)
But I am receiving an error for:
let name = myJson["name"]
fatal error: unexpectedly found nil while unwrapping an Optional value

The first issue you have is this line:
let myJson = try JSONSerialization.jsonObject(with: data!, options: JSONSerialization.ReadingOptions.mutableContainers) as AnyObject
You specify that the data will be of type AnyObject. But it should really be an array of dictionaries. So, instead, you should specify:
let myJson = try JSONSerialization.jsonObject(with: data!, options: JSONSerialization.ReadingOptions.mutableContainers) as [[String:Any]]
Of course, that alone will not fix things since you have to extract items from the array before you can use dictionary notation to get at the "name" value. So, you'd have to do something like this, after that:
let row = myJson[0]
let name = row["name"]
