Use iPhone 14 Pro, iPhone 14 Pro Max to read the IP address of WiFi, but the interface 'en0' for WiFi cannot be obtained, do you know the reason?
Unable to get WiFi for interface 'en0/Ipv4'
Because there’s no guarantee than en0 is the primary Wi-Fi interface on iOS.
Why do you need to identify the primary Wi-Fi interface? This matters because the best path forward depends on what you plan to do with this information. For example, the answer I gave this developer may not be appropriate for your requirements.
