Alternatively, you could try using the beta release of swift, Swift 0.95 RC6 with the new cloud mechanism:<br></div><div class="gmail_default"><font face="arial, helvetica, sans-serif"><a href="https://github.com/swift-lang/swift-on-cloud/tree/master/aws" target="_blank">https://github.com/swift-lang/swift-on-cloud/tree/master/aws</a></font></div>
