How do I restore indexing functionality? (Xcode)
<p>One of my projects (containing over 200 files in pure Swift) has just recently started  interfering with the indexing process. The indexing process freezes midway and then stops abruptly, causing <code>SourceKitService</code> to crash. </p>

<p>I simply cannot find the faulty code; because there appears to be none!</p>

<p>My code compiles just fine (without a single warning!) - and yet it fails to be indexed. Initially, I thought it to be an Xcode 7.2 issue and so upgraded to the latest beta (7.3); however the issue still persists. I cannot revert back to my old code because too much work will be undone, and I can't spot a particular file to blame. The crash report is <a href="https://gist.github.com/vmanot/a57f79b22b1fbf16b8f0" rel="nofollow noreferrer">here</a>.</p>

<p>To clarify, Xcode itself does not crash, only the indexing process (and <code>SourceKitService</code> as a consequence). </p>

<p>Any ideas on how to go about fixing this?</p>
