Enable development mode on your device
Development mode enables you to remotely install and launch your application on a device. When you are not performing development activities, turn off Development mode for increased security. Development mode is disabled automatically when you reboot the device. If you connect to your device using Wi-Fi and a USB cable, your device will have two IP addresses.
To enable Development Mode:
On the home screen, swipe down from the top of the screen.
Tap Settings > Security and Privacy > Development Mode.
Tap the Use Development Mode toggle switch.
If prompted, type the password for your device, and tap OK.
