title: Non-case-sensitive switch statement in swift?
body: <p>I'm playing around with an app that takes in user input, and prints a simple output.</p>
  
  <p>My code looks like this:</p>
  
  <pre><code>switch text {
          case "Hi", "hi", "Hello", "hello", "Good day", "good day":
              return "Hello, sir."
          default:
              return "Sorry, I didn't understand!"
  }
  </code></pre>
  
  <p>My question is, instead of having 5-10 possible inputs for one output, is it possible to put one input that isn't case sensitive? For example, could I just put "hello", and have my statement check for "Hello", "hello", "HELLO", etc.?</p>
