Writes the receiver’s text as RTF with attachments to a file or directory at path.
Declaration
func writeRTFD(toFile path: String, atomically flag: Bool) -> BoolDiscussion
Returns true on success and false on failure. If atomicFlag is true, attempts to write the file safely so that an existing file at path is not overwritten, nor does a new file at path actually get created, unless the write is successful.
