How do I change the NavigationBar font in Swift?

This is what I have tried so far, but receiving an error (I have correctly implemented CaviarDreams

Answer 1

Try this:

self.navigationController.navigationBar.titleTextAttributes = [ NSFontAttributeName: UIFont(name: "CaviarDreams", size: 20)!]

Edit: Now, UIFont must be unwrapped to be able to be used here.

Swift 5 (+ safe handling of optional UIFont)

self.navigationController?.navigationBar.titleTextAttributes = [ NSAttributedString.Key.font: UIFont(name: "Caviar-Dreams", size: 20) ?? UIFont.systemFont(ofSize: 20)]

Answer 2

Swift 4.2

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
  // Override point for customization after application launch.

  let font = UIFont(name: "FontName", size: 16) ?? UIFont.systemFont(ofSize: 16)
  UINavigationBar.appearance().titleTextAttributes = [.font: font]
}

Answer 3

For Swift 2.3

self.navigationController!.navigationBar.titleTextAttributes = [NSFontAttributeName: UIFont(name: "Roboto-Bold", size: 20.0)!, NSForegroundColorAttributeName : UIColor.whiteColor()];

Answer 4

Swift 4

if let font = UIFont(name: "FontName", size: 16) {

 self.navigationController?.navigationBar.titleTextAttributes = [NSAttributedStringKey.font: font]

}

Or as the other answer recommended doing it on the AppDelegate:

  if let font = UIFont(name: "FontName", size: 16) {

    UINavigationBar.appearance().titleTextAttributes = [
          NSAttributedStringKey.font: font]

}

Answer 6

Change Large Title

self.navigationController!.navigationBar.largeTitleTextAttributes = [.font: UIFont.systemFont(ofSize: 22)]

Change Small Title when layout scrolled down

self.navigationController!.navigationBar.titleTextAttributes = [.font: UIFont.systemFont(ofSize: 14)]
