Compiling with Xcode 12 Beta 4

I have a iOS framework which has the following snippet of code :

        CTTelephonyNetworkInfo *netinfo = [[CTTelephonyNetworkInfo alloc] init];
        CTCarrier *carrier = [netinfo subscriberCellularProvider];

In Xcode 11.x compiling target had a "Generic iOS Device" option and I am able to create a fat framework which includes the simulator pieces. However in Xcode there are 2 targets one for arm64 and the other for Intel and Apple Silicon. How do I create a fat framework here?
Something new here? I have the same problem since Xcode 12.
