I want to fetch the list of near by wifi networks and able to connect to them from our App in ios, and my Application is Enterprise App so even private api\'s is also fine. Stuc
Public API allows you to have only information about the current wifi used by your device using CNCopyCurrentNetworkInfo
In order to fetch all the wifi available in your area, take a look at: Stumbler which is using MobileApple80211. I think, it handles what you are looking for. Moreover, you can also use it to connect your device to a specific wifi. You can find a good example of what you need here (answer #9)
Just keep in mind, if you are using private API, your app will be rejected by Apple.
