   Hi Ian,
   
   It looks like the reader is failing while trying to read the schema from the 
footer.  I believe the footer should always have a schema (AFAIK).  Maybe a 
flatbuffer issue (I know Swift Arrow currently targets a specific version of 
flatbuffers as the latest was causing an issue, could be related(?)).  I will 
look into this.
