Dark Mode uses a darker color palette for all screens, views, menus, and controls, and it uses more vibrancy to make foreground content stand out against the darker backgrounds. Dark Mode still supports all accessibility features.
Tap to launch Settings from your Springboard then select Display & Brightness from the Settings menu.
Choose Dark as the appearance mode.
If you prefer to have your device automatically switch between light and dark modes, toggle the Automatic switch to the ON position.
You can then tap Options to either use Dark Mode from sunset to sunrise or set your own custom schedule.
