During Apple’s WWDC 2019 developer session 713 titled, “Advances in Networking” revealed that iOS 13 will stop location tracking using your device’s SSID/BSSID using the CNCopyCurrentNetworkInfo API. Developers have reported getting an email from Apple that says:
Starting with iOS 13, the CNCopyCurrentNetworkInfo API will no longer return valid Wi-Fi SSID and BSSID information. Instead, the information returned by default will be:
SSID: “Wi-Fi” or “WLAN” (“WLAN” will be returned for the China SKU) BSSID: “00:00:00:00:00:00”
