You can use an iPhone as a Nintendo Switch 2 camera

If you're looking to use your iPhone as a camera with your Nintendo Switch 2 and don't want to spend extra on an official camera or cables, here's a concise solution: Plug a USB-C adapter into both devices, connecting them via HDMI capture cable. While this setup might require some tweaking, it allows the iPhone to function as a camera. Be aware of potential lag issues but consider using apps to minimize controls. Alternatively, purchase cheaper cables from Amazon at around $31 or opt for a USB-C webcam if available. Additionally, placing your Switch 2 in the Steam Deck case could provide extra protection and organization with some padding.
