Answer 1

在这里您可以使用[navigationBar.backgroundColor]代替[navigationBar]。 barTintColor]

    navigationItem.title = "Countries"
    
    navigationController?.navigationBar.prefersLargeTitles = true
    
    navigationController?.navigationBar.backgroundColor = UIColor.blue
    
    tabBarController?.tabBar.tintColor = UIColor.white
    
    view.backgroundColor = .white
