The recursive git clone terminates abnormally at the Swift submodule so you can't get Swift and the following submodules. I'm not a git master, so I'm not sure where the problem is.
Error:
error: Server does not allow request for unadvertised object 7afac9bc7848ff460128225686657c9daedd28cc
Fetched in submodule path 'Swift', but it did not contain 7afac9bc7848ff460128225686657c9daedd28cc. Direct fetching of that commit failed.
You can successfully download the ZIP files for the remaining modules however.
