How to turn on the flashlight with iOS Swift

iOS gives us access to the flashlight if there is currently one available on the phone. Technically, its called a torch but whatever lol… Here is a code snippet on how to turn on the torch.

import AVFoundation

func toggleTorch(on: Bool) {
    guard let device = AVCaptureDevice.default(for: AVMediaType.video) else { return }

    if device.hasTorch {
        do {
            try device.lockForConfiguration()

            if on == true {
                device.torchMode = .on
            } else {
                device.torchMode = .off
            }

            device.unlockForConfiguration()
        } catch {
            print("Torch could not be used")
        }
    } else {
        print("Torch is not available")
    }
}
