Hi,
I have been at WWDC and learned about the Swift server side stuff.
In general I feel that this is a very good approach to write
server services in a very modern language which can be developed
and natively deployed on major server platforms, including
Linux-x86, MacOS, LinuxARM (Solaris and Windows properly soon).
In terms of the lower level WebObjects stuff which I know a little
bit, JavaFoundation replacement will be Swift with its Foundation
libraries. JavaEOAccess, JavaEOControl, JavaXML and JavaWebObjects
must entirely redone in Swift, I just tag this job at least 5+
man years engineering time for the basic WO, not talking about our
apps, a generic SQL adapter, Wonder and countless Java libraries
being used in many projects.
I looked a little bit into the low-level Kitura Swift web server
library, at present this is very basic and does not come closed to
the required feature set of WebObjects. This means Kitura is not
of any help.
We will keep our WO projects in Java as this works great, re-doing
it in Swift is unaffordable for us and does not bring any benefits
for our clients. We will also to develop new WO based server apps.
For our company server apps (non WO feature set) I consider Swift
as the way to go, because we can continue to use our existing
native C code and C libraries which is a very good transition,
pretty much what Apple is doing in preserving their low level
libraries which are basically C and Objective-C code based.

Hi -
I’ve been following Swift’s evolution in the
swift-evolution mailing list. As it exists today on the server
is still lacking some key features needed to implement
key-value-coding.
There is a MIrror class that allows you to see the
property names of a class (or even a struct) and get the value
of each property. But it only works for properties. It does
not work for methods in your objects. In addition, it is
read-only, i.e. you can get the values but you cannot set
properties.
Hopefully by Swift 4 or 5 those features will
arrive. But they are not there in Swift 3.
On Apple platforms they are able to use CoreData
because they are leveraging Objective-C run-time. However, the
Objective-C run-time is not available on the server.

I'm just hoping maybe apple will hint at a
server side framework written in swift they will be
releasing to the public :)

Yuri,
I can’t say much right now, as the
video is not available. And, even after I watch
the video, I may still be unable to add anything
to this conversation, as my knowledge lack a lot.
:D
From what I understand, one could
write server-side applications in any language.
For web apps, it’s necessary to integrate said
language with an HTTP server — through CGI, Apache
module or whatever. Apache is pretty much
standard. I tend to think “mod_swift.so” would be
the best solution now...
Still, for something like WebObjects
to be “ported” over to Swift, there’s a lot to be
done. The Enterprise Objects Framework is what
makes it so nice and easy to write WO apps and it
is, by far, the larger part of the code base. And
then there’s wotaskd, the database connectors…
I am sure I am missing something, but
I don’t see where a programming language would
help us. Even if it is incredibly better than
Java, which is a whole different conversation,
with very different opinions, I am sure. ;)
Still, hope springs eternal.
Cheers,
Flavio

Going Server-side with Swift
Open Source
While the Swift language
makes it easy to write software that
is incredibly fast and safe by design,
Swift being open source means you can
use it on an even broader range of
platforms, from mobile devices to the
desktop and in the cloud. Come for an
overview of available projects at Swift.org
and examples of the community in
action.
