In my project, I need get list all near by WiFi in range,
I have already done lots of research but didn't get any solution, Please any one help me for same ?
thanks very much!
By this way you can get all near by your phone
From iOS >= 4.1 it's possible to obtain SSID of wireless network that device is currenctly connected to.
For this you'd use function CNCopyCurrentNetworkInfo
Details on implemenation are available on SO: iPhone get SSID without private library
Without the use of private library (Apple80211) it will not provide you other reachable wifi list or other info but if you want devices near by you You can use multipeer connectivity.

My requirement is like, I want IP and MAC address of devices which are connected to my iOS device's hotspot.
How can I get a list of IP address of those devices?
Does Apple allow to get hotspot related information through code.?
Unfortunately I don't know a way to get the actual client list (or ARP table for that matter).
But you could implement a scanner. Have you thought of that? Isn't the beautiful solution you're most probably looking for, but might be something?
Here would be a scanner library as reference: https://github.com/mavris/MMLanScan
You could also get your devices IP address and network mask, calculate the possible IP range yourself and implement an ARP query per candidate device using sysctl and gethostbyaddr as described in this post

EDIT sidenote:
Did you have a really deep read of the NetworkExtension API from Apple? I don't know it well but since it allows numerous configurations that might be possible as well.
My app should scan Wifi signals around and list the network's name and its RSSI.
I can't find any clue on Google about how to do it. Could someone give an example or at least point somewhere else where I can find the answer?
I dont think its possible ! It doesnt matter if its Swift or Objective-C nor C++, the basic principle of iOS is that only system can connect to WiFi or turn on off those system setting. All you can get is info about the currently connected network. App sandbox in ios limits all other possibility.
It is only possible to get the SSID of the network that you are currently connected to.
I want to get the list of wifi network near my iPhone. Get the details such as signal strength,SSID , MAC Address from the wifi network, without using any 3rd party library (i do not want my app to be stuck off in any review process). please help me , i need to get this going soon.
Simple answer… You can't by using public library. You sure can using private ones, but you don't want apple to reject your app.
I am writing an android app and trying to figure out if there is a reliable way to determine when the phone is on a specific wifi network.
For example, I want to perform certain actions only when connected to the home wifi.
Does anyone know if it's possible?
Yes, there is a way for this on both, android and iOS/iPhone.
On Android, you need to use this method in the end: android.net.wifi.WifiInfo.getSSID
On iPhone it's a completely different world. You can find a good description of how to do it here:
iPhone get SSID without private library
you can get the SSID of the current wifi-connection with :
WifiManager mng = (WifiManager)context.getSystemService(Context.WIFI_SERVICE);
String currentSSID = mng.getConnectionInfo().getSSID();
I checked the Phonegap API but what I would like to achieve, getting a list of available wifi networks, seems not supported.
Anyone knows if it's possible at all in the current state?
You cannot get a list of available wifi networks at the moment.
PhoneGap will support reading the currently connected network SSID via the system information api (http://www.w3.org/TR/system-info-api/#network).
If you wanted to list all the wifi networks today, you would have to write a PhoneGap plugin -- assuming those APIs are actually available on the devices in which you are interested.
Here is a PhoneGap plugin for wifi info https://github.com/HondaDai/PhoneGap-WifiInfoPlugin The code is in Java which means it's for Android. However,
WifiInfo wifiInfo = wifiManager.getConnectionInfo();
This only gives you result for the currently connected wifi network. To get a list of all wifi networks, I believe you can change the WifiInfoPlugin class and use wifiManager.getScanResults(), then store the results in an array or similar.
I recently did some research on this and found out it's still not supported.
It might be useful to have a look at the PhoneGap roadmap from time to time.
