I have couple of URLs that has to be called(programatically) through wifi not with mobile data.

As ***WIFI ASSIST*** is on , whenever the wifi is weak ,packets get transferred through Mobile data.

I would like to stop this from happening.

As far as I have researched, there is *no API to toggle wifi assist* switch on and off programatically 

I can find if the user has mobile data and wifi on with the help of Reachability Class I believe and I can alert the user to keep wifi assist off but this is a very bad user experience.

so I decided to look if its possible to be done with the help of *iOS mobile configuration file*.

But I couldn't find any keys related with wifi-assist in Apple configuration profile reference.

so I am wondering , is it possible to force wifi to be used for certain URLs.

I remember this is possible with VPN ON DEMAND we can have certain domains to be accessed via VPN.

I am wondering if same is possible for wifi as well through configuration profile

Any suggestions are welcome.
