Right now I have to make a Separate “FoozleErrors” enum, which just feels messy.<div class=""><br class=""></div><div class="">I would really like to see us be able to nest Structs, Enums, and even other Protocols within a protocol, and it would just act as a namespace. Wil is right though, that if we can only have one, Enums give us the most bang for our buck. That is the case I run into most often. In addition to Error Enums, I also have a lot of places where protocol functions return a classification (as an enum), and it is cluttering the top-level namespace with things named “Foozle____".</div><div class=""><br class=""></div><div class="">It isn’t a huge issue (it doesn’t stop me from doing anything), but it is an annoyance that I run into all the time… I view the fact that Swift doesn’t support this as a bug.</div><div class=""><br class=""></div><div class="">Thanks,</div><div class="">Jon<br class=""><div class=""><div class=""><div class=""><br class=""></div><div class=""><br class=""><div><blockquote type="cite" class=""><div class="">On Jul 8, 2017, at 6:10 PM, Akshay Hegde <<a href="mailto:akshay_hegde@me.com" class="">akshay_hegde@me.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><meta http-equiv="Content-Type" content="text/html charset=utf-8" class=""><div style="word-wrap: break-word; -webkit-nbsp-mode: space; line-break: after-white-space;" class="">Wouldn’t the following work just as well for providing a namespace?<div class=""><br class=""></div><div class=""><span style="font-family: SFMono-Regular; font-size: 12px;" class="">struct Foozle {</span><br style="font-family: SFMono-Regular; font-size: 12px;" class=""> <span style="font-family: SFMono-Regular; font-size: 12px;" class="">enum Errors: Error {</span><br style="font-family: SFMono-Regular; font-size: 12px;" class=""> <span style="font-family: SFMono-Regular; font-size: 12px;" class="">case malformedFoozle</span><br style="font-family: SFMono-Regular; font-size: 12px;" class=""> <span style="font-family: SFMono-Regular; font-size: 12px;" class="">case tooManyFoozles</span><br style="font-family: SFMono-Regular; font-size: 12px;" class=""> <span style="font-family: SFMono-Regular; font-size: 12px;" class="">}</span><br style="font-family: SFMono-Regular; font-size: 12px;" class=""><font face="SFMono-Regular" class=""><span style="font-size: 12px;" class="">}</span></font></div><div class=""><div class=""></div></div><div class="">
