The ArcGIS Runtime SDK for iOS automatically adds an attribution control at the bottom of the map. It blends well in light appearance but is much more jarring in dark appearance (compare "light-current.png" with "dark-current.png"). Because newer iPhones have a larger area below the safe area (to accommodate rounded screen corners and the home indicator), the attribution control's background is larger than on older iPhones.
Moreover, when combined with a standard iOS tab bar, the bright background of the map attribution control bleeds into the translucent tab bar, reducing its contrast and making its contents harder to read.
My idea is to reduce the apparent brightness of the map attribution control when in dark appearance. For example, by switching to white text on a dark background — see the attached mockup named "dark-proposed.png".
