What I wish is that it were possible to get rid of implicit captures altogether—instead of just inserting [weak self] when you *don’t* want to capture something strongly, also require [strong self] when you do. Referencing self otherwise causes an error. We’d never get away with it now, though, with the source compatibility promise in place.</div><div class=""><br class=""></div><div class="">Charles</div><div class=""><br class=""></div></body></html>
