The simplest way to add paginate (a.k.a infinite scroll) function to your table view.
All you have to do is just set your table view class in the storyboard to PagingTableView, and implement the PagingTableViewDelegate#paginate

PagingTableView is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod "PagingTableView"

See full example here.
To run the example project, clone the repo, and run pod install from the Example directory first.

First set your table view class in the storyboard to PagingTableView

Then implement paginate function. If isLoading is set to true, an indicator is displayed at the bottom of the table view. Otherwise, the indicator disappears and UITableView.reloadData is called.

class MainViewController: UIViewController {

  override func viewDidLoad() {
    ...
    contentTable.pagingDelegate = self
  }

  ...

}

extension MainViewController: PagingTableViewDelegate {

  func paginate(_ tableView: PagingTableView, to page: Int) {
    contentTable.isLoading = true
    contentDataSource.loadData(at: page) { contents in
      self.contents.append(contentsOf: contents)
      self.contentTable.isLoading = false
    }
  }

}
