title: Storing each char from a text field in an array?
body: <p>I'm having trouble  trying to store input from a textfield into an array where each character is at a separate index. </p>
  
  <p>I have tried storing the input as a string so I can make it all upper case and remove white spaces, but this is causing me problems too. </p>
  
  <p>I figured once it is stored I could just loop through each letter and add each char to a mutable array. </p>
  
  <p>Thank you for any help in advance.</p>
