title: Decrease iOS Application size to App Store
body: <p>I am trying to submit an application in App Store, and I need to decrease its memory a little bit, if this is possible. I tried a method which I am gonna describe below to make my app lighter, but with not luck.</p>
  <h1>Details</h1>
  <p>I followed these steps to see what was causing this large size</p>
  <ol>
  <li>Make an archive of the project</li>
  <li>Distribute it</li>
  <li>Save for Enterprise or Ad-Hoc Deployment</li>
  <li>Select the <code>.ipa</code> file and changed the extension to <code>.zip</code></li>
  <li>Extract it, and open Payload</li>
  <li>Show the Package Contents</li>
  </ol>
  <h1>Contents</h1>
  <p>I had <code>.png</code> files with 680 <code>Kb</code> (when I added those where 32 kb approximately), I deleted them and I reduced the size of application by <strong>2 MB</strong>. There are other files that take space but not considerably, except one executable file that is taking about 90 % of the <code>.ipa's</code> size.</p>
  <h1>Question</h1>
  <p>Is it possible to decrease executable file's size? If not then can you give me a hint where I should look to make my app lighter in terms of size.</p>
  <p><em>P.S I use third party libraries like <a href="https://developer.vuforia.com/resources/sdk/ios" rel="noreferrer">Vuforia SDK</a> and libraries on <strong>GitHUB</strong></em></p>
