They now reiterate that Xcode 6.3 requires Yosemite (Mac OS X 10.10). The “Last Modified” date is April 10th, a day after this radar was posted.

MAS version of Xcode 6.3 lists system requirements as "OS X 10.10 or later".

If you check the App Store, Xcode 6.3 is listed as needing OS X 10.10 or later in the "Compatibility" section:
