ios - Xcode 11.4. Navigation's Title Color gone BLACK from storyboard

Question

I recently updated my Xcode to 11.4. When I run the app on the device, i've noticed that all my navigations item's titles gone fully black when being set from storyboard.

You can't change neither from code, the following line of code doesn't work anymore

self.navigationController?.navigationBar.titleTextAttributes = [.foregroundColor: UIColor.white]

I only make it work using some iOS 13 stuffs UINavigationBarAppearance

@available(iOS 13.0, *)
    private func setupNavigationBar() {
        let app = UINavigationBarAppearance()
        app.titleTextAttributes = [.foregroundColor: UIColor.white]
        app.backgroundColor = Constants.Color.barColor
        self.navigationController?.navigationBar.compactAppearance = app
        self.navigationController?.navigationBar.standardAppearance = app
        self.navigationController?.navigationBar.scrollEdgeAppearance = app

        self.navigationController?.navigationBar.titleTextAttributes = [.foregroundColor: UIColor.white]
    }

Can somebody explain me why??? This is a crucial bug, or some new hidden feature?

This fixed it for me, using UINavigationBarAppearance instead, from: Customizing Your App’s Navigation Bar

if #available(iOS 13.0, *) {
    let appearance = UINavigationBarAppearance()
    appearance.configureWithOpaqueBackground()
    appearance.backgroundColor = UIColor.black
    appearance.titleTextAttributes = [.foregroundColor: UIColor.white] // With a red background, make the title more readable.
    self.navigationBar.standardAppearance = appearance
    self.navigationBar.scrollEdgeAppearance = appearance
    self.navigationBar.compactAppearance = appearance // For iPhone small navigation bar in landscape.
} else {
    self.navigationBar.barTintColor = UIColor.black
    self.navigationBar.tintColor = UIColor.white
    self.navigationBar.titleTextAttributes = [.foregroundColor: UIColor.white]
}

Note: I subclassed UINavigationController, and this was called from the override of viewWillAppear.

...or for AppDelegate, app-wide:

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

    let buttonAppearance = UIBarButtonItemAppearance()
    buttonAppearance.normal.titleTextAttributes = [.foregroundColor: UIColor.white]
    appearance.buttonAppearance = buttonAppearance

    UINavigationBar.appearance().standardAppearance = appearance
    UINavigationBar.appearance().scrollEdgeAppearance = appearance
    UINavigationBar.appearance().compactAppearance = appearance

    UIBarButtonItem.appearance().tintColor = UIColor.white
} else {
    UINavigationBar.appearance().barTintColor = UIColor.black
    UINavigationBar.appearance().titleTextAttributes = [
        NSAttributedStringKey.foregroundColor: UIColor.white
    ]
    UINavigationBar.appearance().tintColor = UIColor.white

    UIBarButtonItem.appearance().tintColor = UIColor.white
}

...for AppDelegate, app-wide, in Objective-C:

if (@available(iOS 13, *)) {
    UINavigationBarAppearance *appearance = [[UINavigationBarAppearance alloc] init];
    [appearance configureWithOpaqueBackground];
    appearance.backgroundColor = UIColor.whiteColor;
    appearance.titleTextAttributes = titleAttributes;

    UIBarButtonItemAppearance *buttonAppearance = [[UIBarButtonItemAppearance alloc] init];
    buttonAppearance.normal.titleTextAttributes = barButtonItemAttributes;
    appearance.buttonAppearance = buttonAppearance;

    UINavigationBar.appearance.standardAppearance = appearance;
    UINavigationBar.appearance.scrollEdgeAppearance = appearance;
    UINavigationBar.appearance.compactAppearance = appearance;

    [[UINavigationBar appearance] setTintColor:UIColor.blackColor];
} else {
    [[UINavigationBar appearance] setBarTintColor:UIColor.whiteColor];
    [[UINavigationBar appearance] setTintColor:UIColor.blackColor];
    [[UINavigationBar appearance] setTranslucent:false];
    [[UINavigationBar appearance] setTitleTextAttributes: titleAttributes];
    [[UIBarButtonItem appearance] setTitleTextAttributes:barButtonItemAttributes forState:UIControlStateNormal];
}
