title: Converting from snake case to camel case using keyDecodingStrategy
body: <p>I am trying to use <strong>Codable</strong> to automatically parse incoming <code>JSON</code> into my models. It is working fine, but then I learnt about <code>_keyDecodingStrategy_</code>, and wanted to use this. It is working great and able to lessen my code as I do not have to write <code>CodingKeys</code> enum for my models. </p>
  
  <p>But now the problem is a new variable sent from server. The variable is <em><code>post_url_110x110</code></em>. </p>
  
  <p>I thought it will convert to <em><code>postUrl110x110</code></em>, but it doesn't. Do help me into its <code>camelCase</code> conversion or suggest if I should avoid automatic conversion in this case.</p>
