Navigationview Bar Material Invisible on iOS 15

Transparent iOS navigation bar

You can apply Navigation Bar Image like below for Translucent.

Objective-C:

[self.navigationController.navigationBar setBackgroundImage:[UIImage new]
                     forBarMetrics:UIBarMetricsDefault]; //UIImageNamed:@"transparent.png"
self.navigationController.navigationBar.shadowImage = [UIImage new];////UIImageNamed:@"transparent.png"
self.navigationController.navigationBar.translucent = YES;
self.navigationController.view.backgroundColor = [UIColor clearColor];

Swift 3:

self.navigationController?.navigationBar.setBackgroundImage(UIImage(), for: .default) //UIImage.init(named: "transparent.png")
self.navigationController?.navigationBar.shadowImage = UIImage()
self.navigationController?.navigationBar.isTranslucent = true
self.navigationController?.view.backgroundColor = .clear
    

Tab & Navigation Bar changes after upgrading to XCode 13 (& iOS 15)

About Navigation Bar is black, try do it:

let appearance = UINavigationBarAppearance()
appearance.configureWithOpaqueBackground()
appearance.backgroundColor = .red
appearance.titleTextAttributes = [.font: 
UIFont.boldSystemFont(ofSize: 20.0),
                              .foregroundColor: UIColor.white]

// Customizing our navigation bar
navigationController?.navigationBar.tintColor = .white
navigationController?.navigationBar.standardAppearance = appearance
navigationController?.navigationBar.scrollEdgeAppearance = appearance

I wrote a new article talking about it.
