Hi everybody I'm new and i want to start to learn swift but i have a linux Os (a son of Debian) and, if i understand correctly, doesn't exist a good IDE for Swift on linux not? I don't want to start with VSCode because i prefer to see what i'm doing without test on my personal smartphone and i can't have an another phone...
Thanks for the answers... 
Hi @NoNameoN,
GitHub - pwsacademy/swift-setup: Student-friendly setup instructions for platforms, editors, and IDEs that support Swift. should help you get started.
Note that this doesn't explain how to use Swift, only how to set up an editor or IDE.
Try to use CLion - it's the best solution for now.
CLion is paid, but you can use it within 30 minutes and then reopen the app again
You can also try Visual Studio with Sourcekit-lsp plugin
And if you want to build some UI there's
SwiftGTK
and
Tokamak
also Cacao is here but it's unmaintained anymore
A couple words to add to the @GothStar's post:
To use CLion for Swift you'll need to install the Swift plugin. Here's the installation guide & some details about the plugin: Swift | CLion.
If you're a student, you can get a free CLion license at JetBrains Products for Learning.
@egor.zhdan Would you be interested in contributing instructions for CLion on Mac and Linux to GitHub - pwsacademy/swift-setup: Student-friendly setup instructions for platforms, editors, and IDEs that support Swift.? I could write them myself, but I'm hoping others will step in to maintain instructions for the IDEs/platforms they use 
I'm looking forward to the Windows release of CLion + Swift btw!
Yeah, I'll most likely add the CLion guide a bit later, unless somebody else is faster than me No ETA for now, sorry.
The instructions will be pretty much the same for macOS & Linux (and Windows once the Swift plugin supports it).
Thanks @egor.zhdan!
Please also check the guides for Swift macOS/Ubuntu/etc, as that's what the IDE instructions should be based upon. In particular:
PATH.
