Can you elaborate on this? I can't make this work. (I remember that I
tried this before and failed.)

Here's an example of how I'm trying to invoke it:

set_property(GLOBAL PROPERTY
CMAKE_XCODE_ATTRIBUTE_SWIFT_OBJC_INTERFACE_HEADER_NAME
"BlurrrSwiftInterfaceHeader.h")

This seems to get ignored. (But if I use a per-target setting, then it works.)

Thanks,
Eric
