Answer 1

Thank you, everyone, after being looking for answer to change the tabbar color I found the answer to this question earlier my my AppDelegate was .

UINavigationBar.appearance().backgroundColor = UIColor(red: 159/255, green: 31/255, blue: 99/255, alpha: 100)
UINavigationBar.appearance().tintColor = UIColor.white
UINavigationBar.appearance().titleTextAttributes = [NSAttributedString.Key.foregroundColor:UIColor.white] 

Now I changed this to

UINavigationBar.appearance().barTintColor = UIColor(red: 159/255, green: 31/255, blue: 99/255, alpha: 100)
UINavigationBar.appearance().tintColor = UIColor.white
UINavigationBar.appearance().titleTextAttributes = [NSAttributedString.Key.foregroundColor:UIColor.white] 

and my problem was solved
