title: Consonants and Vowels Swift
body: <p>I'm new at Swift, could anyone explain to me why I'm keep getting this problem. I'm using Xcode 6.4, but here is my question I hope I cleared it up but I needed my Function to takes in Large String then returns Tuple(numVowels, numConsonants)
  Count the number of words that start with consonants/vowels
  Return the Tuple and print the result of the function call. 
  I did not need for it to count characters, only first character of each word.  I create an for loop which will switch everything to lowercase. But now I'm stuck.  </p>
  
  <pre><code>func count(string: String) -&gt; (Vowels:Int, Consonants:Int) {
      var Vowels = 0, Consonants = 0
      for character in string {
          switch String(character).lowercaseString {
              case "a","e","i","o","u":
                ++Vowels
              case "b","c","d","e","f","g","h","j","k","l","m","n","p","q","r","s","t","v","w","x","y","z":
              ++Consonants
          default: break
          }
  
      }
      return (Vowels, Consonants)
  }
  </code></pre>
