detecting if iPhone is in a dark room

Question

Is there a way to use the iPhone proximity sensor to detect whether the phone is in a room with no light?

This question seems to imply that this is not possible...Do

Answer 1

There is much simpler solution for this if anyone needs. Use screen brightness to detect the light conditions:

0 - 0.3 (Dark)

0.4 - 1 (Bright)

Tweak as needed:

switch UIScreen.main.brightness {
    case 0 ... 0.3:
        print("LOW LIGHT")
    default:
        print("ENOUGH LIGHT")
    }
