[WM] - Alternative to Use() in iOS

Hello,

I am converting an app that was originally developed for Android to iOS.

In this wherever I had the need to show one window and close all other windows I have used the Use() function. And this works properly in my Android app.

But when I try to generate the XCode project WM list Use() function as not supported.

Any idea if there is an alternative to this in iOS.

Please help.

TIA
