Swift - Control Flow

Given this enum and switch, how can you make the switch exhaustive without listing all cases explicitly?

enum Status { case success, failure, unknown }
let currentStatus = Status.unknown
switch currentStatus {
 case .success: print("Success")
 case .failure: print("Failure")
}

AAdd a <code>default</code> case to handle all other values.

BRemove the switch and use if-else instead.

CAdd a case for .unknown explicitly.

DChange enum to have only two cases.

Step-by-Step Solution

Solution:

Step 1: Understand the problem with current switch
The switch handles .success and .failure but misses .unknown, so it's not exhaustive.
Step 2: Find a way to cover missing cases without listing all explicitly
Adding a default case covers any cases not explicitly handled, making the switch exhaustive.
Final Answer:
Add a default case to handle all other values. -> Option A
Quick Check:
Use default to cover missing cases = A [OK]

Quick Trick: Use default to cover all unlisted cases quickly [OK]

Common Mistakes:

Thinking you must list every case explicitly
Removing switch instead of fixing it
Changing enum just to fix switch
