id warning: directory not found for option
<p>I have been using Xcode 6 and I am using Xcode 7.3 beta 3 now and I got this warning</p>

<blockquote>
  <p>ld: warning: directory not found for option
  '-F/Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS9.3.sdk/Developer/Library/Frameworks'</p>
</blockquote>

<p>I've read something to go to "Project > Build Sittings > Search Path > Framework Search Paths" and I found it empty as you can see in the picture below.</p>

<p>Does anybody know how or what should I do?</p>
