How can I download Swift? I've been trying to get my hands on Swift, but I can't seem to find it.  Is it released yet?  If not, when will it be released?
To use Swift, download Xcode 6 and start using it to develop iOS 8 apps.  Mac apps will become available with the release of Yosemite. More resources are available here: https://developer.apple.com/swift/resources/
