Woohoo! It's done! My gift to you on the first day of 2025: I just made my progressive blur UI component open source. Introducing BlurUIKit! 🎉 https://github.com/TimOliver/BlurUIKit I really hope Apple make this effect actually official in iOS 19. If you're an app developer, please dupe FB13949531 (also on OpenRadar) asking Apple very nicely to make that happen. 🤞
