[swift-users] Pointer conversions between different sockaddr types

[Bouke Haarsma]

Hi Quinn, and others,

I found that this code is still featured on swift.org 
(https://swift.org/migration-guide/se-0107-migrate.html), but it 
doesn't compile anymore. There's a fix-it for adding @escaping, but 
also compile errors due to invalid casts. Can someone have a look at 
fixing this code?
