Xcode 6.3 builds all swift files twice

Question

I just upgraded to Xcode 6.3, and am attempting to reduce the compile time to something manageable. I have ~120 swift files/classes in my project and it\'s taking 2-3 minute

Answer 1

Change the Build Active Architecture Only setting for Debug and any other non-Release configuration from No to Yes. You want it to be Yes when you build for distribution, but otherwise having it set to No means your files won't be compiled twice.
