Answer 1

Swift 5/Xcode 11

Write this code as extension from UINavigationBar

extension UINavigationBar {
    func customNavigationBar() {
        // color for button images, indicators and etc. 
        self.tintColor = UIColor.Custom.mainAppColor

        // color for background of navigation bar
        // but if you use larget titles, then in viewDidLoad must write
        // navigationController?.view.backgroundColor = // your color
        self.barTintColor = .white
        self.isTranslucent = false

        // for larget titles 
        self.prefersLargeTitles = true

        // color for large title label
        self.largeTitleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.someColor]

        // color for standard title label 
        self.titleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.someColor]

        // remove bottom line/shadow
        self.setBackgroundImage(UIImage(), for: .default)
        self.shadowImage = UIImage()
    }
}

then in AppDelegate.swift call UINavigationBar.appearance().customNavigationBar() in didFinishLaunchingWithOptions function

For iOS 13 you have to change the color in the appearance property and for older iOS versions you can do it directly in the navigation bar property.

if #available(iOS 13.0, *) {
    navigationController?.navigationBar.standardAppearance.titleTextAttributes = [.foregroundColor: UIColor.white]
} else {
    navigationController?.navigationBar.titleTextAttributes = [.foregroundColor: UIColor.white]
}

The didSet is called if your set the user, maybe you're setting the user's name variable and expecting the program to enter didSet. try setting the user.

And if you want to change the color of the text when the navigation title is changed to the name of the user just call this code.

navigationController?.navigationBar.titleTextAttributes = [NSForegroundColorAttributeName : UIColor.red]

var user: User? {
    didSet {
        navigationItem.title = user?.name
    }
}

override func viewDidLoad() {
    super.viewDidLoad()

    let newUser = User()
    newUser.name = "John Doe"
    user = newUser
}

in objetive c:

[UINavigationBar appearance] setTitleTextAttributes: 
    [NSDictionary dictionaryWithObjectsAndKeys: 
        [UIColor blackColor], NSForegroundColorAttributeName, 
           [UIFont fontWithName:@"ArialMT" size:16.0], NSFontAttributeName,nil]];

Solution for iOS 13

To customize the appearance of a navigation bar you need to use UINavigationBarAppearance:

let appearance = UINavigationBarAppearance()
appearance.titleTextAttributes = [.foregroundColor: UIColor.red]
appearance.largeTitleTextAttributes = [.foregroundColor: UIColor.red]

navigationItem.standardAppearance = appearance
navigationItem.scrollEdgeAppearance = appearance

create project and test this with ViewController easy to use

import UIKit
class ProfileViewController: UIViewController {
      override func viewDidLoad() {
        super.viewDidLoad()
        configureNavigationBar()
          
          }
        func configureNavigationBar() {
            navigationItem.title = "Profile"
   let textChangeColor =[NSAttributedString.Key.foregroundColor:UIColor.black]
navigationController?.navigationBar.titleTextAttributes = textAttributes
              navigationItem.rightBarButtonItem?.tintColor = .white
            navigationItem.rightBarButtonItem = UIBarButtonItem(image: #imageLiteral(resourceName: "arrow_right").withRenderingMode(.alwaysOriginal), style: .plain, target: self, action: #selector(handleDismiss))
              navigationController?.navigationBar.prefersLargeTitles = true
            navigationItem.rightBarButtonItem?.tintColor = .white
                    }
}
