An easy way to add Peek and Pop to UITableViewController
Just use this as your superclass instead of UITableViewController and implement the tableView(tableView:, peekViewControllerForRowAt:) method:
class MyCustomTableViewController: JS3DTouchTableViewController {
...
override func tableView(_ tableView: UITableView, peekViewControllerForRowAt indexPath: IndexPath) -> UIViewController? {
return someViewController
}
}
