Example of setting up an enum for UITableView sections.

EnumTableViewTutorial_01.swift

class ViewController: UIViewController {
  
  // The magic enum to end our pain and suffering!
  // For the most part the order of our cases do not matter.
  // What is important is that our first case is set to 0, and that our last case is always `total`.
  enum TableSection: Int {
    case action = 0, comedy, drama, indie, total
  }
  
  // This is the size of our header sections that we will use later on.
  let SectionHeaderHeight: CGFloat = 25
  
  // Data variable to track our sorted data.
  var data = [TableSection: [[String: String]]]()
  
}
