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

Answer 1

The cleanest solution I've found is to simply include your last statement in the switch case as your default. This avoids the need to add break or other unnecessary statements while still covering all possible cases.

For example:

switch myVar {

case 0:
    myOtherVar = "Red"

case 1:
    myOtherVar = "Blue"

default:
    myOtherVar = "Green"

}
