title: Type 'Bool' does not conform to protocol 'Sequence'
body: <p>I started learning Swift few weeks ago and in one lesson (Arrays and for .. in loops) I had to make func that counts votes and gives an answer.</p>
  
  <p>So I made this code thinking thats it but this error pops in -> "Type 'Bool' does not conform to protocol 'Sequence'"</p>
  
  <p>here's the code:</p>
  
  <pre><code>func printResults(forIssue: String, withVotes: Bool) -&gt; String {
      positive = 0
      negative = 0
      for votes in withVotes {
          if votes == true {
              positive += 1
          } else {
              negative += 1
          }
      }
      return "\(forIssue) \(positive) yes, \(negative) no"
  }
  </code></pre>
  
  <p>The error pops in 4th line with 'withVotes' </p>
  
  <p>There are already some arrays that got Bool type values. </p>
