Swift has a feature for handling >5GB files.

1) Split your file into chunks that are less that 5GB each (this is currently the responsibility of the client)

2) Upload each chunk, concurrently if desired

3) Create a manifest file that ties together all of the chunks. When accessing the manifest object, all of the component parts are streamed serially to the client
