Scanning a code on an iPhone is pretty simple. You can use the built-in Camera app: just open it and point your device at the QR code, and a notification should pop up for you to tap. Alternatively, use the Control Center by adding the "Code Scanner" feature for a quicker option. Have you tried scanning codes before, or is this your first time trying it out? If you face any challenges, feel free to share, and I can help troubleshoot!
