Try with below code

First you need to change in below line, its Dictionary<String, Any> not an AnyObject

let json = try JSONSerialization.jsonObject(with: data, options: JSONSerialization.ReadingOptions.mutableContainers) as! Dictionary<String, Any>

And then get applicationStateJson by below code

if let appJson = json["applicationStateJson"] as? Dictionary<String, Any> {
    print(appJson)
    print("Email : \(appJson["email"] as? String ?? "Email not found")") // For get email
}

The root object of the JSON is a clearly a dictionary, not AnyObject (an object but I-have-no-idea-what-it-is).

The value for key applicationStateJson is a dictionary, too.

do { 
   if let json = try JSONSerialization.jsonObject(with: data) as? [String:Any],
      let applicationStateJson = json["applicationStateJson"] as? [String:Any] {
         print(applicationStateJson)
   }
} catch { 
   print(error)
}

As always, .mutableContainers is completely meaningless in Swift
