While Swift 2 did introduce OptionSetType for structs, it still feels somewhat obtuse and non-obvious. It would be great if we could something like:<div class=""><br class=""></div><div class=""><div style="margin: 0px; line-height: normal; font-family: 'Courier New';" class="">options NotSoSecretVariations {</div><div style="margin: 0px; line-height: normal; font-family: 'Courier New';" class=""><span class="Apple-tab-span" style="white-space:pre"> </span>case ProteinStyle,</div><div style="margin: 0px; line-height: normal; font-family: 'Courier New';" class=""><span class="Apple-tab-span" style="white-space:pre"> </span>case AnimalStyle,</div><div style="margin: 0px; line-height: normal; font-family: 'Courier New';" class=""><span class="Apple-tab-span" style="white-space:pre"> </span>case GrilledOnions,</div><div style="margin: 0px; line-height: normal; font-family: 'Courier New';" class=""><span class="Apple-tab-span" style="white-space:pre"> </span>...</div><div style="margin: 0px; line-height: normal; font-family: 'Courier New';" class="">}</div></div><div class=""><br class=""></div><div class="">That said, I have a feeling this isn’t the first time the Swift team has come across a pitch like this. If this really is unfeasible, it would be great and really educational to hear what the challenges are.</div><div class=""><br class=""></div><div class="">Dan</div></body></html>
