title: XCode 6 GM: Constantly freezing / locking while editing Swift code
body: <p>Since installing XCode 6 GM, it has been freezing and locking, showing the spinning wheel of death while I attempt to edit code that has syntax errors.  Has anyone else seen this, and are there any known work-arounds?  </p>
  
  <p>I foolishly abandoned my cautious strategy of saving the previous version (Beta 7) and it appears that Beta 7 is no longer available for download.  Are there any known archives of / for the link?</p>
  
  <p>I have also posted to the dev forums and will follow up with a bug report, but it is hard to pin down the exact circumstances.</p>
  
  <h1>Edit:</h1>
  
  <p><strong>Additonal Notes:</strong></p>
  
  <p>CPU: SourceKit Service is generally around 100%, but that has seem to have been the norm for the flavors of XCode, and the CPU seems to properly drop off when it finishes recompiling.</p>
  
  <p>RAM: SourceKit is no longer exhibiting the memory leaks that used to cause it to halt and catch fire, memory does not appear to be a factor, and there are several ~ 5+ gigs to spare.</p>
  
  <p><strong>Environment:</strong></p>
  
  <p>Late 2012 Mac Mini, 16GB RAM 
  OS X 10.9.4 (to be fair, this was new today as well, driven by the requirements of XCode 6 GM).</p>
  
  <p>That said, only the software changed today.</p>
  
  <h1>Update</h1>
  
  <p>Apple claims that this bug is fixed in Beta 6.1, for what it's worth.</p>
