Method 2: Using custom image as a back button.

Paste below code into your detailVC and set image for your back Button.

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.

   title = "Detail VC"

    let customButton = UIBarButtonItem(image: UIImage(named: "back"), style: .plain, target: self, action: #selector(backButtonTapped)) //
    self.navigationItem.leftBarButtonItem  = customButton  
}

func backButtonTapped() {     
   _ = navigationController?.popToRootViewController(animated: true)  
}

I am setting back button image in assets catalogue with the 32pixel size.I am not sure about the asset image size.Check with apple doc about the size class.
