 <p><a href="http://swift-lang.org/tryswift/" rel="nofollow">http://swift-lang.org/tryswift/</a> doesn't look like it's anything to do with Apple Swift. The "try Swift" page you're using is for <a href="https://en.wikipedia.org/wiki/Swift_%28parallel_scripting_language%29" rel="nofollow">Swift</a>, not <a href="https://en.wikipedia.org/wiki/Swift_%28Apple_programming_language%29" rel="nofollow">Swift</a>.</p> <p>Note that Apple's has the stylised <a href="https://en.wikipedia.org/wiki/Swift" rel="nofollow">swift</a> in its logo heading downwards; the parallel scripting language Swift is heading upwards :)</p> <p>To try Apple's Swift in a similar way, you'll need the Xcode 6 beta and a "playground" file.</p>
