iOS13 Navigation bar large titles not covering status bar

Use my extension iOS 13 Swift 5 tested

extension UIViewController {
func configureNavigationBar(largeTitleColor: UIColor, backgoundColor: UIColor, tintColor: UIColor, title: String, preferredLargeTitle: Bool) {
    if #available(iOS 13.0, *) {
        let navBarAppearance = UINavigationBarAppearance()
        navBarAppearance.configureWithOpaqueBackground()
        navBarAppearance.largeTitleTextAttributes = [.foregroundColor: largeTitleColor]
        navBarAppearance.titleTextAttributes = [.foregroundColor: largeTitleColor]
        navBarAppearance.backgroundColor = backgoundColor

        navigationController?.navigationBar.standardAppearance = navBarAppearance
        navigationController?.navigationBar.compactAppearance = navBarAppearance
        navigationController?.navigationBar.scrollEdgeAppearance = navBarAppearance

        navigationController?.navigationBar.prefersLargeTitles = preferredLargeTitle
        navigationController?.navigationBar.isTranslucent = false
        navigationController?.navigationBar.tintColor = tintColor
        navigationItem.title = title

    } else {
        // Fallback on earlier versions
        navigationController?.navigationBar.barTintColor = backgoundColor
        navigationController?.navigationBar.tintColor = tintColor
        navigationController?.navigationBar.isTranslucent = false
        navigationItem.title = title
    }
}}

How to use:

configureNavigationBar(largeTitleColor: .yourColor, backgoundColor: .yourColor, tintColor: .yourColor, title: "yuorTitle", preferredLargeTitle: true)

Set ViewController-based status bar...... to NO in info.plist if you want light Content

If you don't want largeTitles set it to false

for tranlsucent change navBarAppearance.configureWithOpaqueBackground() in:

navBarAppearance.configureWithDefaultBackground()
navigationController?.navigationBar.isTranslucent = true

in the call set background color to .clear

UPDATE: If you want to start with navigation controller and large Titles at first controller, don't forget to set launch controller in Scene Delegate like this:

guard let windowScene = (scene as? UIWindowScene) else { return }
window = UIWindow(windowScene: windowScene)
window?.makeKeyAndVisible()
let vC = UINavigationController(rootViewController: YourFirstViewController())
window?.rootViewController = vC

hope this help :)

For full application navigation bar support please add this extension inside your code.

import UIKit
extension UIViewController {


    open func showNavigationBar(_ large: Bool,
                                _ animated: Bool,
                                titleColor: UIColor,
                                barTintColor: UIColor,
                                fontSize: CGFloat) {

        navigationController?.navigationBar.barTintColor = barTintColor
        navigationController?.navigationBar.backgroundColor = barTintColor
        navigationController?.navigationBar.isTranslucent = true
        self.navigationController?.setNavigationBarHidden(false, animated: animated)
        if large {
            self.navigationController?.navigationBar.prefersLargeTitles = true
            if #available(iOS 13.0, *) {
                let appearance = UINavigationBarAppearance()
                appearance.backgroundColor = barTintColor
                appearance.titleTextAttributes = [.foregroundColor: titleColor]
                appearance.largeTitleTextAttributes = [NSAttributedString.Key.foregroundColor: titleColor,
                                                       NSAttributedString.Key.font: UIFont(resource: R.font.robotoMedium, size: fontSize)!]

                navigationController?.navigationBar.standardAppearance = appearance
                navigationController?.navigationBar.compactAppearance = appearance
                navigationController?.navigationBar.scrollEdgeAppearance = appearance
            } else {
                self.navigationController?.navigationBar.largeTitleTextAttributes = [NSAttributedString.Key.foregroundColor: titleColor,
                                                                                     NSAttributedString.Key.font: UIFont(resource: R.font.robotoMedium, size: fontSize)!]
            }
        } else {
            self.navigationController?.navigationBar.prefersLargeTitles = false
            self.navigationController?.navigationBar.titleTextAttributes = [NSAttributedString.Key.foregroundColor: titleColor,
                                                                            NSAttributedString.Key.font: UIFont(resource: R.font.robotoMedium, size: 20.0)!]
        }
    }
}

And Then call this method simply

self.showNavigationBar(true, true, titleColor: UIColor.blue, barTintColor: UIColor.red, fontSize: 32.0)

The official way to customize the UINavigationBar, pre iOS 13, is this:

// text/button color
UINavigationBar.appearance().tintColor = .white
// background color
UINavigationBar.appearance().barTintColor = .purple
// required to disable blur effect & allow barTintColor to work
UINavigationBar.appearance().isTranslucent = false

iOS 13 has changed how navigation bars work, so you'll need to do things slightly differently to support both old & new:

if #available(iOS 13.0, *) {
    let appearance = UINavigationBarAppearance()
    appearance.backgroundColor = .purple
    appearance.titleTextAttributes = [.foregroundColor: UIColor.white]
    appearance.largeTitleTextAttributes = [.foregroundColor: UIColor.white]

    UINavigationBar.appearance().tintColor = .white
    UINavigationBar.appearance().standardAppearance = appearance
    UINavigationBar.appearance().compactAppearance = appearance
    UINavigationBar.appearance().scrollEdgeAppearance = appearance
} else {
    UINavigationBar.appearance().tintColor = .white
    UINavigationBar.appearance().barTintColor = .purple
    UINavigationBar.appearance().isTranslucent = false
}
