Issue

• For some reasons in iOS10.x barTintColor is not working on some of the sharing containers.
• But there's a workaround to fix the Navigation bar colour on all the sharing containers.

Solution

• Use UINavigationBar.appearance() to change the navigation bar colour.
• Use backgroundColor property & setBackgroundImage(_:for:) method to fix the navigation bar colour.

Code

/// Method to set navigation bar color
func setNavigationBar() -> Void
{
    // barTintColor will apply color for the app's navigation bar
    UINavigationBar.appearance().barTintColor       = UIColor.blue

    // backgroundColor will apply color for some of the sharing container's app except for Messages app
    UINavigationBar.appearance().backgroundColor    = UIColor.blue

    // backgroundImage will apply the color image for navigation bar for most of the sharing container's except for `Notes`
    UINavigationBar.appearance().setBackgroundImage(UIImage(color: UIColor.blue), for:UIBarMetrics.default)
}

/// UIImage extension to create an image from specified color
extension UIImage
{
    public convenience init?(color: UIColor, size: CGSize = CGSize(width: 1, height: 1)) {
        let rect = CGRect(origin: .zero, size: size)
        UIGraphicsBeginImageContextWithOptions(rect.size, false, 0.0)
        color.setFill()
        UIRectFill(rect)
        let image = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()

        guard let cgImage = image?.cgImage else { return nil }
        self.init(cgImage: cgImage)
    }
}

Hope it helps!.
