An article today on iMore suggests a brilliant way Apple could (and should) implement a system wide Dark Mode within iOS. ------ 'Apple could take it a step further, though, and provide a "NightKit" framework for its standard UIKit interface system, then any App Store app could tie into it as well. That way customers could choose Dark Mode once in Settings and have it automatically enabled everywhere, in every app that supports it, all at once. Like Night Shift, it could live in Settings > Display and Brightness, and be toggled on or off from Command Center at any time. For developers, a framework could conceivably let them tweak parameters and set colors so that their app's interface looks exactly the way the developer wants in either light or dark modes'. ------ I love it!
