Hello, ntewfik.
From what I've read and understand, you want to know how you can clear/see the saved Wi-Fi connections. I may be able to help. While there isn't a way or a list that you can pull up of all the saved Wi-Fi networks besides going to Settings > Wi-Fi. From there you would have to manually tap on the "i" in order to forget the network. The other option is to reset your network settings in which this would erase all saved networks. To do this, tap Settings > General > Reset > Reset Network Settings. This also resets Wi-Fi networks and passwords, cellular settings, and VPN and APN settings that you’ve used before.
Cheers!
