title: Hitting strange error: "DOMException 105" in IOS app. Looking for guidance on how to locate the bug in my code
body: <p>Having trouble finding any reference to this error - anywhere!</p>
  
  <p>It happens at the same point every time - just as I click on a UITableView row element.  Below is the stack trace - can someone provide any suggestions as to what the problem might be and/or how to go about finding the bug?</p>
  
  <p>Thank you!</p>
