Answer 1

You can hide back button text in many ways.Try this simple approach.

Step1: Goto your mainstoryBoard and click navigationBar .

Step 2: Goto Attributes Inspector under Navigation Item add a BLANK SPACE in Back Button

Step 3: If you want to change backButton text method is pretty much the same.

Update 1: If you want to use an image as a back button check this link

Update 2:

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 32 pixel size.I am not sure about the asset image size.Check with apple doc about the size class.

Answer 2

Create a new UIBarButton and add it the navigationItem.leftBarButton .

let backButton = UIBarButtonItem(image: UIImage(named:"yourImage"), style: .plain, target: self, action: #selector(yourBackMethod(sender:))
navigationItem.leftBarButtonItem = = backButton


@objc internal func yourBackMethod(sender: AnyObject) {
  navigationController.popViewController()
}

Hope this helps.
