Interval Matching Using Switch in Swift

You may have learned how enums are best used with switch from the previous articles, but wondered how the switch statement handles matching cases with a specific range or interval.

In Swift, you can create a range of values as a switch case using the built-in range operators.

A great example of it would be handling the response code from a network call. The response code is a number for a standard HTTP code.

switch response.code {
case 200...299:
	print("Success")

case 400...599:
	print("Failed")

default:
	print("Unsupported")
}
