It seems TestPropertyWrapperMacro.swift is not in your current working directory.

You can run pwd to get your current working directory and ls to list directory contents to verify it.

Or you can specify the full path instead of relative path of your intended file.

A working example :down_arrow:

echo 'print("Hello")' >> example.swift

ls -lah
total 8
drwx------@   3 kyle  staff    96B Apr  2 21:26 .
drwx------@ 408 kyle  staff    13K Apr  2 21:26 ..
-rw-r--r--@   1 kyle  staff    15B Apr  2 21:26 example.swift

swiftc -dump-ast example.swift

do i just copy the pathname of my test file and then change the "cd pathname" and then run this command would this work ?
