macOS flag is: -mmacosx-version-min=xx.yy
iphoneos flag is: -mios-version-min=xx.yy
iphonesimulator flag is: -mios-simulator-version-min=xx.yy
but for xros things are going crazy ....
xros flag -mtargetos=xrosxx.yy
works well
xrsimulator flag -mtargetos=xrosxx.yy
or -mtargetos=xrsimulatorxx.yy
are not working
Does anyone no which is the right flag
