I am interested in writing Swift code on Linux. Now I know I can install Swift on Linux, that's great. Does the Linux installation of Swift also include CoreData? That would be terrific.

Also, is it possible to compile C code and link it to Swift code on Linux, as it is possible on MacOS?

I found this description but it is more than three years old at this point; has there been some progress since then?

Yes, it is possible to put C into a Swift Package. Such C packages can be linked with other Swift Packages. For example, see "Imported C and Objective-C APIs"

However, CoreData is not part of the cross platform Swift Foundation Libraries.

As a crossplatform from persistant data alternative to CoreData, it is possible to use SQLite C with a layer that provides a Swift API.

Vapor server and companion iOS app examples provides a discussion an approach to have C & Swift packages which run cross platform on iOS, macOS and Linux.

  • Re your rejected edits on [tag:swift], please (re-)read [the tag wiki excerpt guidance](https://unix.stackexchange.com/help/tag-excerpts), in particular point 4. – Stephen Kitt May 14 '19 at 21:17
  • @StephenKitt Unlike Q&A, the tag edit process provides for limited communication and revision. It's voted up or down. At this moment, [Acer Swift](https://unix.stackexchange.com/search?q=OpenStack+Swift) and [OpenStack Swift](https://unix.stackexchange.com/search?q=Acer+Swift) return as many results the [[swift](https://unix.stackexchange.com/questions/tagged/swift)] tag on the Unix & Linux Stack Exchange. As such, the re-submit comment noted that the _'swift' tag itself can be ambiguous_ in the context of Unix/Linux ... for re-evaluation, per your prior comment. ... – marc-medley May 14 '19 at 22:46
  • @StephenKitt ... the tag wiki had _**no text whatsoever**_ when I started trying to proposing what seemed to be a resonable minimal something better than nothing ... https://unix.stackexchange.com/posts/518779/revisions. The rejects are OK. Your feedback is appreciated. And, your current edits look like a good example. So, in the end, it took both our efforts to go from zero to something useful. Peace. ;-) – marc-medley May 14 '19 at 22:48
