dealing with nested json array swift - json

Question

I am trying to convert some json data which i receive from a get request into a usable array or something like this
the json data i recieve looks like this
{
"elementlist":{
"Ready Position":{
"Neutral Grip":["1,2,3,4,5"],"
Back Straight (Concave ir Convex?)":["1,2,3,4,5"],"
Body Low & Feet a little more than sholder width apart":["1,2,3,4,5"],"
Weight on Balls of Feet":["1,2,3,4,5"],"
Head Up":["1,2,3,4,5"],"
Sholder Blades Close":["1,2,3,4,5"],"
Eyes Drilled":["1,2,3,4,5"]
},
"Split Step":{"
Ready Position Conforms":["Yes,No"],"
Body Position Low":["1,2,3,4,5"],"
Legs Loaded/Prepared":["1,2,3,4,5"]
}
}
}
this is the swift i am using
let playerAPIurl = "http://linkcoachuat.herokuapp.com/api/v1/session/element?organisation=5&group=green&sport=tennis"
var request = URLRequest(url: URL(string: playerAPIurl)!)
request.httpMethod = "GET"
let configuration = URLSessionConfiguration.default
let session = URLSession(configuration: configuration, delegate: nil, delegateQueue: OperationQueue.main)
let task = session.dataTask(with: request) { (data, response, error) in
if error != nil {
print("ERROR")
}
else{
do{
print("hello")
let myJson = try JSONSerialization.jsonObject(with: data!, options: []) as? [String: Any]
// Convert myJson into array here
print(myJson)
}
catch
{
}
}}
What i would like to be able to do is get an array of the names of the nested arrays so elementarray = ["Ready Position","Split Step"] and then be able to access the arrays by saying myJson[elementarray[0]] or something similar
im a bit of a swift noob so any help is appreciated please try and explain the answers so they are easily understood
thank you for any help

You can try to downcast that json same way you've already made:
let myJson = try JSONSerialization.jsonObject(with: data!, options: []) as? [String: Any]
//creating the new array of additional elements
let elementArray: [[String: Any]] = []
//making myJson parsing for additional items
if let readyPosition = myJson?["Ready Position"] as? [String: Any] {
elementArray.append(readyPosition)
}
if let splitStep = myJson?["Split Step"] as? [String: Any] {
elementArray.append(splitStep)
}
make print(elementArray) to be sure that all was parsed correctly.
Honestly, I prefer to use objects (custom classes or structs) to store values and have an ability to make related instances or values, but up to you
