Invalid Toolchain message even though app not submitted with beta software
<p>I am trying to submit a project to the app store. I accidently opened it in the latest Xcode Beta - but did not save or change anything. </p>

<p>I submitted the app with Xcode 7.3.1 and when I attempt to submit the app for review I get the message: <code>"New apps and app updates must be built with the public (GM) versions of Xcode 6 or later, macOS, and iOS SDK. Don't submit apps built with beta software including beta macOS builds."</code></p>

<p>If I check the Info.plist of the archive it also mentions me using the public version of Xcode</p>

<pre><code>&lt;key&gt;DefaultToolchainInfo&lt;/key&gt;
&lt;dict&gt;
    &lt;key&gt;DisplayName&lt;/key&gt;
    &lt;string&gt;Xcode 7.3.1 Default&lt;/string&gt;
    &lt;key&gt;Identifier&lt;/key&gt;
    &lt;string&gt;com.apple.dt.toolchain.XcodeDefault&lt;/string&gt;
&lt;/dict&gt;
</code></pre>

<p>The Xcode beta version was not open when submitting and I also tried restarting and then resubmitting. Btw I am running El Cap 10.11.6 </p>

<p>What can I do to fix this?</p>

<p>Thanks</p>
