Adding table view to detail view controller - ios

Question

I am in the process of making my first app. Right now I am trying to make a settings page. So far it looks like this.
I have the split view controller hooked up to a master view controller and a detail view controller (code below). As you can see, right now there is a table view on the left side of the split view controller containing different buttons. When each button is pressed I want it to display a list of words on the right side of the view controller. It does display a list of words already but I want it to display the words stacked horizontally in a table view and I am not sure how to go about doing this.

#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
let splitViewController = self.window!.rootViewController as! UISplitViewController
let leftNavController = splitViewController.viewControllers.first as! UINavigationController
let MasterViewController = leftNavController.topViewController as! MasterViewController
let Detail = splitViewController.viewControllers.last as! Detail
let firstWord = MasterViewController.words.first
Detail.word = firstWord
MasterViewController.delegate = Detail
return true
}
PS. If you look at the MasterViewController code you will see where it says "description". the lists contained in description is what should be displayed in the table view on the right.

Answer 1

In the func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath), of the masterviewcontroller, you need to replace the viewcontroller.
Get the splitviewcontroller instance from the appdelegate, now to the splitview controllers view controller property assign your desired viewcontroller object, and make sure your desired view controller object has a navigation controller.
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
if indexPath.row == 1 {
let storyBoard : UIStoryboard = UIStoryboard(name: "Main", bundle:nil)
let splitViewController = appDelegate.window!.rootViewController as! UISplitViewController
let nextViewController = storyBoard.instantiateViewController(withIdentifier: "yourviewcontrollername") as! UINavigationController
splitViewController.viewControllers[1] = nextViewController
}
