XCode 8.3.2 Storyboard UI elements won't appear in simulator

Question

disclaimer: I've found a number of these questions but none of them helped.

Just like the title says, the storyboard UI elements for my CarDetailViewController won't appear in the simulator, but they do in other view controllers in the project.

vc in question

overall project

code:

import UIKit
import EventKit
import CoreData


class CarDetailViewController: UIViewController, 
UIImagePickerControllerDelegate, UINavigationControllerDelegate, 
NSFetchedResultsControllerDelegate {


/* -------------------------------------------------------------------------------------------------------- */
let managedObjectContext = (UIApplication.shared.delegate as! AppDelegate).persistentContainer.viewContext

/* -------------------------------------------------------------------------------------------------------- */

@IBOutlet weak var myImageView: UIImageView!
let picker = UIImagePickerController()
@IBOutlet weak var carLabel: UILabel!

@IBAction func photoFromLibrary(_ sender: UIButton) {
    picker.allowsEditing = false
    picker.sourceType = .photoLibrary
    picker.mediaTypes = UIImagePickerController.availableMediaTypes(for: .photoLibrary)!
    present(picker, animated: true, completion: nil)

}

override func viewDidLoad() {
    super.viewDidLoad()
    picker.delegate = self
    self.view = UIImageView(image: UIImage(named: "Landing.png"))
    // Do any additional setup after loading the view.

}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

@nonobjc func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String: AnyObject])
{
    let chosenImage = info[UIImagePickerControllerOriginalImage]
    myImageView.contentMode = .scaleAspectFit //3
    myImageView.image = chosenImage as? UIImage //4
    dismiss(animated: true, completion: nil) //5
}

func imagePickerControllerDidCancel(_ picker: UIImagePickerController)
{
    dismiss(animated: true, completion: nil)
}


/*
// MARK: - Navigation

// In a storyboard-based application, you will often want to do a little preparation before navigation
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    // Get the new view controller using segue.destinationViewController.
    // Pass the selected object to the new view controller.
}
*/

}

Answer 1

Try this :

Remove this Line :

self.view = UIImageView(image: UIImage(named: "Landing.png"))

You need to set background image as

  self.view.backgroundColor = UIColor(patternImage: UIImage(named:"Landing.png")!)

Answer 2

you donot assign an imageview into a uiview so instead of

self.view = UIImageView(image: UIImage(named: "Landing.png"))

You have the following options:

1. You should add a uiimageview into your uiview and assign it that image.
2. you can create a gradient background color with this image.

IMHO use the first approach, as the second might cause resolution issues with different devices

Edit update: Instead of initializing the vc as following

let destination = CarDetailViewController() // Your destination

try doing the following

let storyboard = UIStoryboard(name: <Storyboard-name>, bundle: nil)
let inquireViewController = storyboard.instantiateViewController(withIdentifier: String(describing:CarDetailViewController.self)) as! CarDetailViewController
