The reason, I think, is that Xcode 6.0.x was released to support iOS 8 
when iOS 8 was released so it does not include an OS X 10.10 SDK since 
10.10 wasn't released at that point yet.  Xcode 6.1 will support iOS 8.1 
which apparently is anticipated to release on Monday 10/20 US time so I 
would expect to see Xcode 6.1 released via the Mac App Store then as 

Apparently, Apple decided (somewhat understandably) that it wasn't worth 
the effort to rev bump Xcode 6.0.x just to include a 10.10 SDK just for 
the four days between the release of 10.10 and the release of 8.1 and 
they didn't want to publicly pre-release an 8.1 SDK.  Thus we're in this 
weird limbo state - unless you are a member of one of the (paid) Apple 
Developer programs that give non-disclosure access to pre-releases.  Why 
Apple chose to not release 10.10 and 8.1 simultaneously may never be 
known but it could just be they didn't want to overload the Interwebz 
and/or their support organizations.
