I have not.
I guess you're right, in relation to the Swift language usage I mentioned
earlier, this port does appear to need libswiftAVFoundation.dylib at runtime.
And maybe it is expecting to find it within Xcode on your system. (It depends
on what @rpath expands to. I forget what the command is to interrogate a binary
about its rpaths.)
Swift is still a new programming language and I don't think we have many ports
in MacPorts that use Swift so I'm not sure if this should be considered normal
or not.
I see that I have many copies of libswiftAVFoundation.dylib on my system,
within various applications' bundles, so I guess Apple expects people to
include copies of the Swift dylibs with their application.
On my 10.15 system, it does not link with @rpath/libswiftAVFoundation.dylib. It
links with various Swift dylibs in /usr/lib/swift. Maybe the port can be made
to do so on 10.13 as well.
You should file a bug report about this mpv problem.
