Noop for Swift's Exhaustive Switch Statements

Question

Swift requires exhaustive switch statements, and that each case have executable code.

'case' label in a 'switch' should have at least one executable statement

Has anybody settled on a good way to handle the cases where you don't want to actually do anything? I can put a println() in there, but that feels dirty.

Answer 1

According to the book, you need to use break there:

The scope of each case can’t be empty. As a result, you must include at least one statement following the colon (:) of each case label. Use a single break statement if you don’t intend to execute any code in the body of a matched case.
