Obj-C - Programmatically setting NSWindow Appearance to NSAppearanceNameVibrantDark, not working

Using XCode Version 9.4.1 (9F2000) I would like to dynamically allow the user to change the theme of a Mac app from Light to Dark etc, but I'm falling at the first hurdle.

I tried putting the following code in both applicationDidFinishLaunching and ViewController's viewDidLoad methods, but neither caused the theme to change to Dark theme.

NSAppearance* appearance = [NSAppearance appearanceNamed:NSAppearanceNameVibrantDark];
    [self.window setAppearance:appearance];

I was unable to find an Apple sample showing how to do this programmatically. Can anyone point out what I've overlooked??

I was able to get it to work by moving my code to the controller's viewWillAppear (as per sample below). Then everything is themed correctly!

- (void)viewWillAppear {
    [super viewWillAppear];

    NSAppearance* appearance = [NSAppearance appearanceNamed:NSAppearanceNameVibrantDark];
    [self.view.window setAppearance:appearance];
}
