I have check all possible solutions to get list of all available Wifi's but nothing works for me. I even try NEHotspotConfigurationManager API but it connect to wifi with predefined SSID. In my case I need to get the list only.
Do we need entitlement document for NEHotspotNetwork?
This is not still possible in iOS. It doesn't look like there's a way to retrieve a list of currently available SSIDs, without using private APIs which would result in rejection from App Store submission of your app.
