I want to get wifi's SSID and password from server and I have to check any available wifi's SSID is matched with my server's SSID. If any matched, I have to connect with that wifi using its password. I have read many post related to this but I couldn't get any answer.
This is not possible in iOS. The only thing you can retrieve is the SSID after the user has connected to one of the Wi-Fi networks using the regular iOS UI.
You can use Hotspot Configuration to register SSID/password to connect to.
For more info, see iOS - How to programmatically connect to a WiFi network given the SSID and Password using a private/3rd party library

I am implementing an app through Xamarin.
Is it possible to programmatically connect to an SSID which is already remembered by the phone in iOS?
No, it is not possible to connect to a known network, without providing the necessary credentials, due to various security reasons.
In order to connect to a network, you need to create a NEHotspotConfiguration
The class requires either only SSID (for open networks), or SSID with some credentials for authentication.
After the configuration is created, you can connect via NEHotspotConfigurationManager like so:
await NEHotspotConfigurationManager.SharedManager.ApplyConfigurationAsync(config);
NB: Keep in mind that to connect to a network, you need to enable the Hotspot capability in your App Capabilities Working with capabilities.
Is it possible to connect to WLAN using swift, in case I receive WLAN SSID and password from API with my permissions, and before connection I also accept Terms & Conditions. So as a user I totally agree that to happen through a particular app. So I'll search for/or get my local area network by name/WLAN SSID, and connect to it by password but all should go through code. The point is that even though I've a secured wlan, everyone who comes to my store and has my app to be able to connect to wifi even though it's secured.
I am working on a project in which I should connect an iPhone to an accessory via WIFI.
Some blogs spoke about ExternalAccessory.framework but this one is used for establishing connection via Bluetooth.
What library should I use to achieve this ? Could any one please point me to the right direction ? Thanks.
(Assuming that you don't know the ip address of the device you want to connect to)
From an iOS standpoint you want to use NSNetService to discover devices on the network which you can connect to.
This requires that your other device can use mdnsresponder to publish its details onto the network such that it can be found and connected to.
If you do know the ip address (or, once you do know it) then you can use NSURLConnection / NSStream to connect to the device (depending on what capabilities it offers).
When a user walks into a physical store, is it possible to verify if a particular WiFi SSID is available (may be searching with first few characters) and if yes, can we automatically connect to that WiFi programmatically? Getting consent from the user for first time is OK, but if user gives the consent, we should be able to automatically connect subsequent times. I know Captive framework can be used to get the connected WiFi details, but can we leverage that framework to implement the above requirement as well? Appreciate any quick inputs.
No, this is not possible. You can indeed only get the SSID once connected.
I was exploring regarding Wi-Fi Direct and came accross with conclusion that WiFi -certified devices can connect one-to-one or one-to-many and not all connected products need to be Wi-Fi Direct-certified. One Wi-Fi Direct enabled device can connect to legacy Wi-Fi certified devices.So by this we can conclude like if one device is having WiFi direct and other device is having Wifi one can easily connect to it.
I have following queries please help me to resolve.
1.This Wifi Direct is there in Android ICS onwards.So i am trying to connect WiFi Direct of my Samsung Note 2 having Jelly Bean with another Samsung Mobile Galaxy Y duos having Ginger Bread that only has WiFi but i am unable to detect? Can anyone help me in finding reason for this?
2.Another thing i studied is Wifi Direct device will become as access point means it will create an Ad-hoc network ? So why another Wifi devices are not detecting it?
To find a wifi direct device in access point list of a normal wifi u need to create a wifi direct group. For this you need to first connect two wifi direct devices out of which one will act as a group owner and other as client. Once a group is created group owner act as a normal access point for legacy devices(Wifi devices).
Thus you need to create a Wifi Direct group first
