title: make an array of arrays in swift
body: <p>so I've been having trouble with my code, specifically where I have these arrays:  </p>
  
  <pre><code>var messageIntents = ["Send a message", "Send message", "Text", "Send text", "Send a text"]
  var weatherIntents = ["weather", "what's the weather", "how's the weather", "the weather"]
  var musicIntents = ["play", "i want to hear", "shuffle"]
  </code></pre>
  
  <p>The goal is to check to see if a string is equal to one of the values in the arrays. Rather than check these arrays one by one, I would like to make an array of arrays to check them all. Is that possible? And how would I check it?</p>
