> Hi all,<br>> <br>> As Ted mentioned in his email, it is great to finally kick off discussions for what concurrency should look like in Swift. This will surely be an epic multi-year journey, but it is more important to find the right design than to get there fast.<br>> <br>> I’ve been advocating for a specific model involving async/await and actors for many years now. Handwaving only goes so far, so some folks asked me to write them down to make the discussion more helpful and concrete. While I hope these ideas help push the discussion on concurrency forward, this isn’t in any way meant to cut off other directions: in fact I hope it helps give proponents of other designs a model to follow: a discussion giving extensive rationale, combined with the long term story arc to show that the features fit together.<br>> <br>> Anyway, here is the document, I hope it is useful, and I’d love to hear comments and suggestions for improvement:<br>> <a href="https://gist.github.com/lattner/31ed37682ef1576b16bca1432ea9f782" target="_blank">https://gist.github.com/<wbr>lattner/<wbr>31ed37682ef1576b16bca1432ea9f7<wbr>82</a><br>> <br>> -Chris<br>> <br>> <br>><span class="gmail-m_157869858268366294Apple-converted-space"> </span>
