title: Why do my TableView cells need reuse identifiers?
body: <p>To practice my programming and keep track of my progress I'm building an app for myself. I've created a tableview and for each section and independent cells for each requirement. Now Xcode is upset because each prototype cell doesn't have an identifier.</p>
  <p>I've looked at the Swift docs and gone through Youtube vids on the topic but I still don't understand what reuse identifiers are or what they are used for, let alone how it would help in my case.</p>
