In my life coding, I always put a comment where a break would be that reads
// intentionally omitted break
I'd vote something like that.

@elephantronic I love the phrase "life coding"!
I go with a boring /* fallthrough */
myself. I agree, this should always been commented if you mean to leave out the break
.
switch (foo) {
case 1:
// stuff
// *** fallthrough! ***
case 2:
// moar stuff
break;
default:
}
from objective-c-style-guide.
hm .. I think I have never in my life had a switch that lets cases fall through ... I find it confusing and easy to miss out on when debugging.
I have either completely overlapping cases:
case 1: case 2: case 5:
// stuff
break;
or
case 1:
//stuff 1
break;
case 2
//stuff 2
break;
etc.
from objective-c-style-guide.
I suggest we always include a default:
case.
switch (condition) {
case 1: {
// ...
break;
}
case 2: {
// ...
break;
}
default: {
// ...
break;
}
}
I don't think the braces are necessary all the time, but definitely when a case contains more than one line.

More over: if you are switching on an enumeration default
is not needed.

If you are switching on an enumeration, it's recommended practice to not include a default case because the compiler cannot warn you for unhandled values.
