Summary:
If a user types a println statement with an extra quotation mark before a string, then deletes one of the extra marks, Xcode crashes.

Steps to Reproduce:
1. Lauch Xcode 6 beta
2. Create a new playground
3. Type (or paste) the following two lines of code:
     var aValue = 0
     println(aValue, " "some string" )
4. Remove the first or second quotation mark from the string.
5. crash.


Expected Results:
When removing the first quotation mark (") from the string: 
      println(aValue, " "some string" )
I expect to be left with a resulting string:
      println(aValue,  "some string" )

Actual Results:
Xcode 6 beta crashes with the error "SourceKitService Terminated Editor functionality temporarily limited.

Version:
Xcode 6.0 (6A215I)

Notes:
I know the code sample above is not valid code, but it probably still shouldn't crash Xcode.

Configuration:
MacBook Pro Retina, 15-inch, Late 2013
16 GB 1600 MHz DDR3
NVIDIA GeForce GT 750M 2048 MB
OS X 10.9.3 (13D65)
