GM release of Xcode 6 compile

Question

I just downloaded the GM release of Xcode 6 and it won\'t compile with this error:

Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault         


        

Answer 1

In my case i changed 3 places:

Target > Build Settings > Swift Compiler >

• Optimization Level.
  • Debug: None [-Onone]
  • Distribution: Fastest [-O]
  • Release: Fastest [-O]

When i changed just Debug, i have errors like "Source Kit crashed...." This combination of parameters, works very good for me!
