Swift Programmatically Navigate to Another View Controller/Scene

Programmatically navigate to another view controller/scene

I already found the answer

Swift 4

let storyBoard : UIStoryboard = UIStoryboard(name: "Main", bundle:nil)
let nextViewController = storyBoard.instantiateViewController(withIdentifier: "nextView") as! NextViewController
self.present(nextViewController, animated:true, completion:nil)

Swift 3

let storyBoard : UIStoryboard = UIStoryboard(name: "Main", bundle:nil)

let nextViewController = storyBoard.instantiateViewControllerWithIdentifier("nextView") as NextViewController
self.presentViewController(nextViewController, animated:true, completion:nil)

Swift programmatically navigate to another view controller/scene

Swift 5

The default modal presentation style is a card. This shows the previous view controller at the top and allows the user to swipe away the presented view controller.

To retain the old style you need to modify the view controller you will be presenting like this:

newViewController.modalPresentationStyle = .fullScreen

This is the same for both programmatically created and storyboard created controllers.

Swift 3

With a programmatically created Controller

If you want to navigate to Controller created Programmatically, then do this:

let newViewController = NewViewController()
self.navigationController?.pushViewController(newViewController, animated: true)

With a StoryBoard created Controller

If you want to navigate to Controller on StoryBoard with Identifier "newViewController", then do this:

let storyBoard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let newViewController = storyBoard.instantiateViewController(withIdentifier: "newViewController") as! NewViewController
        self.present(newViewController, animated: true, completion: nil)

How to Navigate from one View Controller to another using Swift

Create a swift file (SecondViewController.swift) for the second view controller
and in the appropriate function type this:

let secondViewController = self.storyboard.instantiateViewControllerWithIdentifier("SecondViewController") as SecondViewController
self.navigationController.pushViewController(secondViewController, animated: true)

---

Swift 2+

let mapViewControllerObj = self.storyboard?.instantiateViewControllerWithIdentifier("MapViewControllerIdentifier") as? MapViewController
self.navigationController?.pushViewController(mapViewControllerObj!, animated: true)

---

Swift 4

let vc = UIStoryboard.init(name: "Main", bundle: Bundle.main).instantiateViewController(withIdentifier: "IKDetailVC") as? IKDetailVC
self.navigationController?.pushViewController(vc!, animated: true)

Navigate from a ViewController to an another on didSelectRowAt programmatically

Here is a complete answer:

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    let newViewController = NewViewController()
    self.navigationController?.pushViewController(newViewController, animated: true)
}

How to Navigate between Viewcontrollers without any action from user swift

I think u do not require a segue for this. U can just push navigation Controller.

let storyBoardHome = UIStoryboard(name:storyBoardName, bundle: nil)

 let 1stViewController = storyBoardHome.instantiateViewController(withIdentifier: <1stViewControllerID>)


let 2ndViewController = storyBoardHome .instantiateViewController(withIdentifier: 2ndViewControllerID) 


self.navigationController?.pushViewController(1stViewController/2ndViewController, animated: true)

Navigate one collection view controller to another collection view controller?

I did by my own... here I am attaching my code 1st I created struct

import Foundation
struct City {
    var image:String = ""
    var name:String = ""
    
    init(image: String, name: String){
        self.image = image
        self.name = name
    }
}

after that I enter code for my 1st cell view controller

import UIKit

    private let reuseIdentifier = "Cell"
    
    class cityCollectionViewController: UICollectionViewController {
        var cities : [City] = [ City(image: "Ankara", name: "Ankara"),
                                            City(image: "Antalya", name: "Antalya"),
                                            City(image: "Aydin", name: "Aydin"),
                                            City(image: "Bodrum", name: "Bodrum"),
                                            City(image: "Canakkale", name: "Canakkale"),
                                            City(image: "Cappadocia", name: "Cappadocia"),
                                            City(image: "Efes", name: "Efes"),
                                            City(image: "Eskisehir", name: "Eskisehir"),
                                            City(image: "Fethiye", name: "Fethiye"),
                                            City(image: "Istanbul", name: "Istanbul"),
                                            City(image: "Izmir", name: "Izmir"),
                                            City(image: "Mardin", name: "Mardin"),
                                            City(image: "Nemrut", name: "Nemrut"),
                                            ]
    
        override func viewDidLoad() {
            super.viewDidLoad()
    
        }
    
        
    
        // MARK: UICollectionViewDataSource
    
        override func numberOfSections(in collectionView: UICollectionView) -> Int {
            
            return 1
        }
    
    
        override func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
            
            return cities.count
        }
    
        override func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
            var cell = collectionView.dequeueReusableCell(withReuseIdentifier: "dataCell", for: indexPath) as! cityCollectionViewCell
                
                    
            cell.cityImageView.image = UIImage(named: cities[indexPath.row].image )
            cell.cityNameLabel.text = cities[indexPath.row].name
                
                    return cell
        }
        override func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
                let imageDetailVC = self.storyboard?.instantiateViewController(withIdentifier: "collectCollectionViewController") as! collectCollectionViewController
    
    /
                self.navigationController?.pushViewController(imageDetailVC, animated: true)
           
            }

       
        
    
    
    
    }

created a data cell and gave the outlets

import UIKit

class cityCollectionViewCell: UICollectionViewCell {
    @IBOutlet weak var cityImageView: UIImageView!
       @IBOutlet weak var cityNameLabel: UILabel!
    
}

This is for my second cell view controller

import UIKit

private let reuseIdentifier = "Cell"

class collectCollectionViewController: UICollectionViewController {


    override func viewDidLoad() {
        super.viewDidLoad()
        
        
    }

   var obj = cityCollectionViewController()
    var app1 = secondCollectionViewCell()
    override func numberOfSections(in collectionView: UICollectionView) -> Int {
        
        return 1
    }


    override func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
        

        return obj.cities.count
    }

    override func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {

        let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "Datacell1", for: indexPath) as! secondCollectionViewCell
        let city1 = obj.cities[indexPath.row]
        cell.image11.image = UIImage(named: obj.cities[indexPath.row].image)
        cell.label11.text = obj.cities[indexPath.row].name
        

        return cell
    }


    

}

This code for my second data view cell

import UIKit

class secondCollectionViewCell: UICollectionViewCell {
    @IBOutlet weak var image11: UIImageView!
    @IBOutlet weak var label11: UILabel!
}

Switch programmatically from a viewcontroller to another

Your first bit of code doesn't work because EndViewController is a type. You should replace this with secondViewController that you declared above.

The second bit of code doesn't work because you are creating an 'empty' EndViewController type and not instantiating the storyboard view .

I'm guessing the third bit of code is failing because your storyboard isn't called "EndViewController" (unless you've renamed it). Try changing this to "Main" instead.
