Load a uiviewcontroller in main controller section

Question

I'm trying to load all controllers in the main controller. Trying to use main controller as a navigation controller.

I try modal segue but I can only load the first one because even if i can see the navigation on the main controller I'm not able to press it.

I think that the top controller have to be resized to contrains but I have not being able to find how.

Here is the screenshot of what I'm trying to achieve.
The controllers need to go in the orange section.

To understand your question more clearly, why are you not embedding the main View Controller in a navigaton controller? That will make loading other view controllers easy by just pushing them onto the navigation stack. — as diu, Sep 04 '17 at 17:41

Here is the answer. Found an old tutorial and just made some adjustments. Maybe helps someone else.

MenuCV

import UIKit

class MenuCV: UIViewController {
@IBOutlet weak var tableView: UITableView!
var containerView: ContainerVC?
var menuItems = [String]()

override func viewDidLoad() {
    super.viewDidLoad()

    tableView.delegate = self
    tableView.dataSource = self

    menuItems = ["Dashboard", "Companies", "Makes"]

}

}

extension MenuCV: UITableViewDataSource, UITableViewDelegate {
func numberOfSections(in tableView: UITableView) -> Int {
    return 1
}

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return menuItems.count
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

    guard let cell = tableView.dequeueReusableCell(withIdentifier: "menuCell") as? MenuTVC else { return UITableViewCell() }

    let image = UIImage(named: "logo")

    cell.configureCell(menuIcon: image!, menuLbl: menuItems[indexPath.row])

    return cell
}

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {

    containerView?.segueIdentifierReceivedFromParent(button: menuItems[indexPath.row])
}

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    if segue.identifier == "container" {
        containerView = segue.destination as? ContainerVC
    }
}

 }

ContainerVC

import UIKit

class ContainerVC: UIViewController {

var vc : UIViewController!
var segueIdentifier : String!
var lastViewController: UIViewController!

override func viewDidLoad() {
    super.viewDidLoad()
    segueIdentifierReceivedFromParent(button: "Dashboard")
}

func segueIdentifierReceivedFromParent(button: String){

self.segueIdentifier = button
    self.performSegue(withIdentifier: self.segueIdentifier, sender: nil)

}

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    if segue.identifier == segueIdentifier{
        //Avoids creation of a stack of view controllers
        if lastViewController != nil{
            lastViewController.view.removeFromSuperview()
        }
        //Adds View Controller to Container
        vc = segue.destination
        self.addChildViewController(vc)
        vc.view.frame = CGRect(x: 0,y: 0, width: self.view.frame.width,height: self.view.frame.height)
        self.view.addSubview(vc.view)
        vc.didMove(toParentViewController: self)
        lastViewController = vc

    }
}

}

DashboardVC

import UIKit

class DashboardVC: UIViewController {


override func viewDidLoad() {
    super.viewDidLoad()

}

}

CompaniesVC

import UIKit

class CompaniesVC: UIViewController {

override func viewDidLoad() {
    super.viewDidLoad()

}

}

MakesVC

import UIKit

class MakesVC: UIViewController {

override func viewDidLoad() {
    super.viewDidLoad()

}

}

EmptyVC

import UIKit

class EmptyCV: UIStoryboardSegue {

override func perform() {

}

}
