2015-08-27 Swift Switch must be exhaustive

In Swift, the switch/case statement must contain a default case, otherwise you'll get the following compiler error:

    Switch must be exhaustive, consider adding a default clause

We used to put a non-sensical log statement in there, but today, a colleague found out that you can use the break keyword.

Example:

	switch (self.type!.integerValue) {
	case CustomerTypeNormal.integerValue:
		name = "\(self.lastname?.lowercaseString.capitalizedString), \(self.firstname?.lowercaseString.capitalizedString)"
	case CustomerTypeCrew.integerValue:
		name =  "Crew"
	case CustomerTypeAnonymous.integerValue:
		name = "Anonymous"
	default:
		break
	}
