Connect to a certain Wifi network?

I know it was something that Apple did not allowed, but i could see that some things had changed with iOS9 .

So , for example you can know your SSID name with CaptiveNetwork , and even the password.

Sometimes you have to connect to a certain hardware using wifi so instead of sending a user to settings, we would like to do that in code .

1. is it possible ?
2. is that requires Apple permission? if yes, is it something hard to get ? depends on ?

thanks .
