title: I am using FRC to display random pairs on my tableview
body: <p>I am able to separate my persons objects into arrays of 2 randomly but I can't figure out how to display the pairs on my tableview. Here is my randomizer function. </p>
  
  <pre><code>func randomizer(array: [Person]) {
          guard let array = fetchedResultsController.fetchedObjects else { return  }
          let randomGenerator = GKRandomSource.sharedRandom().arrayByShufflingObjects(in: array)
          let splitSize = 2
          let _ = stride(from: 0, to: randomGenerator.count, by: splitSize).map {
              randomGenerator[$0..&lt;min($0 + splitSize, randomGenerator.count)]
          }
      } 
  </code></pre>
  
  <p>Here is my tableview functions:</p>
  
  <pre><code>func numberOfSections(in tableView: UITableView) -&gt; Int {
          guard let sections = PersonController.sharedController.fetchedResultsController.sections else { return 0 }
          return sections.count
      }
  
  func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -&gt; Int {
      guard let sections = PersonController.sharedController.fetchedResultsController.sections else {
          return 2 }
      let sectionInfo = sections[section]
      return sectionInfo.numberOfObjects
  
  }
  </code></pre>
