title: Swift Filter other arrays based on another Bool array
body: <p>I have an array of Bools and want to edit an array of Scores and an array of Dates for the values that are False. I can't get to it. I thought of getting elements that are false and using that array to remove those elements from the score array but I can imagine there is a direct way of doing it.</p>
  
  <pre><code>let hbiCompleteArray = [true, true, true, true, false, true, true, false, false]
  
  let hbiScoreArray = [12, 12, 12, 12, 3, 13, 13, 2, 2]
  </code></pre>
  
  <p>I want an array of completeHbiScores = [12, 12, 12, 12, 13, 13]</p>
