title: Reading JSON properties without structure/model
body: <p>How can we extract arrays from server response JSON strings?</p>
  
  <p>The JSON object is serialized as such:</p>
  
  <pre><code>    do {
          if let json = try JSONSerialization.jsonObject(with: data, options: .mutableContainers) as? [String: Any] {
          print(json)  // output below                      
          }
      } catch let error {
          print(error.localizedDescription)
      }
  </code></pre>
  
  <p>and the resulting output is:</p>
  
  <pre><code>    ["locations": &lt;__NSArrayM 0x280e23f90&gt;(
      {
          lat = "123.111111";
          long = "1.111111";
      },
      {
          lat = "123.222222";
          long = "1.222222";
      },
      {
          lat = "123.333333";
          long = "1.333333";
      }
      ),
      "mobileNo": 55551234, 
      "clientID": 2123456789, 
      "date": 10082019, 
      "time": 1854]
  </code></pre>
  
  <p>How do we read the properties like <strong>mobileNo</strong> and <strong>clientID</strong> from the <strong>json</strong> variable, and more importantly, how do we place the <strong>locations</strong> array into an array or dictionary?</p>
  
  <p>Thanks for any help.</p>
