+1 for lower camel & case _<span></span><br><br>On Saturday, 27 February 2016, Joel Lopes Da Silva via swift-evolution <<a href="mailto:swift-evolution@swift.org">swift-evolution@swift.org</a>> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div style="word-wrap:break-word">I agree with Michel that we might as well standardize on "case _" instead of “default”.

One unfortunate wrinkle here is that it’s not at all uncommon to have a case named “Default” for an enumeration.
