Question

This is the code I written in AppDelegate class (Swift 4):

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.
     UIApplication.shared.statusBarStyle = .lightContent
    goToRootViewController()
    UINavigationBar.appearance().isTranslucent = true

    UINavigationBar.appearance().shadowImage = UIImage()
    UINavigationBar.appearance().setBackgroundImage(UIImage(), for: .default)
    GMSServices.provideAPIKey(googleMapApiKey)
    return true
}

but my status bar is not showing the light content I dont know what is ging on, Any help?

Answer 1

For Specific ViewController Class:

In your viewcontroller class use this code below viewDidLoad() :

override var preferredStatusBarStyle : UIStatusBarStyle {
    return .lightContent
}

this will show your status bar in light content

For Whole App:

Set "View controller-based status bar appearance" Key with Value "NO" in your product's Info.plist

Then Use Following code in AppDelegate.Swift inside "didFinishLaunchingWithOptions":

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.
    
    UIApplication.shared.statusBarStyle = .lightContent
    return true
}
