Server-side Swift. The Perfect library, application server, connectors and example apps.
Server-side Swift - Perfect | Perfect.org perfect will simplify your coding by using swift for all of your server-side and client-side apps.
Perfect - https://www.perfect.org - is a new web server which lets you use the same language on the server-side as you do on your the device. It will be compatible with the Linux version of Swift when it is released before the end of this year - presumably because it just uses Swift's standard library,
It has connectors for MongoDB, MySQL, PostgreSQL.
Currently, I'm developing an app using the Realm database in Swift. Will I be able to use Realm on the server-side too? Does it just use the Swift standard library?
