prefersStatusBarHidden not updating after calling setNeedsStatusBarAppearanceUpdate() Different vcs inside my app show the status bar visible and others are hidden. This is set to YES in the info.pList "View controller-based status bar appearance": YES // also tried togging this between yes and no "Status bar is initially hidden": YES The app has 2 windows, the main window and a second window. The second window gets presented it front of the main window on a button push. The vc in the second window has the status bar hidden. The problem is if I'm on a vc (mainVC) inside the main window that shows the status bar, I press the button to show the second window, mainVC's status bar disappears. The second window gets presented and after I dismiss it I send a notification to mainVC to call setNeedsStatusBarAppearanceUpdate() but prefersStatusBarHidden isn't triggered so the status bar stays hidden even though it shouldn't be. I even subclassed a Naviga

To make translatable strings I have the following code in my my .vue files: <translate>Hello %{name}</translate> <a href="..." v-translate>Click here</a> (using translate tags and v-translate attributes) Is there a way to configure manage.py makemessages to parse this code as well?
