Recognizing Font Uninstall on visionOS
My visionOS app can install custom fonts. My visionOS app also lists these fonts as available within the application, and I can see them in a list using CTFontManagerCopyAvailableFontFamilyNames I manually track which fonts have been installed. So far, so good. But here’s my problem: When a user uninstalls a font via Settings, I have no way to tell. That’s because CTFontManagerCopyAvailableFontFamilyNames will still list that font because it’s still available within the application. How can I track these changes in my app when a font is uninstalled via Settings?
