Do I need bcsymbolmap files created by Carthage : <p>I am using Carthage dependency manager in my iOS project.
I have the <code>Carthage/build</code> folder in my repository to always have ready to go built frameworks when checking out the repo.</p>

<p>I am wondering what the <code>bcsymbolmap</code> files in the build folder are for. Quite a few of them are created with every <code>carthage update</code>. </p>

<p>Do I need to keep these files? Should I have them in my repository? </p>
