iPhone VR Settings

Hi Team,

Can you explain me the settings to setup iPhone VR in unreal 4.17.
I checked the project settings but there is no specific setup for iPhone like Android, google Daydream or GearVR.
I need to run VR under latest iPhone OS(11.0.0 and above) and using Gamepad controller connected with iPhone I need to move the camera inside application.
Please help me am in a tight schedule to complete my project.

Thanks.
