I'm writing a Swift client to communicate with a server (written in C) on an embedded system. Its not iOS/OSX related as I'm using the recently released Ubuntu version.
Does Swift have any native support for concurrency? I'm aware that Apple discourages developers from using threads and encourages handing tasks over to dispatch queues via GCD. The issue is that GCD seems to be only on Darwin (and NSThread is a part of Cocoa).
For example, C++11 and Java have threads and concurrency as a part of their standard libraries. I understand that platform specific stuff like posix on unix could be used under some sort of C wrapper, but for me that really ruins the point of using Swift in the first place (clean, easy to understand code etc.).
Quoting from Swift's GitHub, there's a readme for "evolutions" :
Concurrency: Swift 3.0 relies entirely on platform concurrency primitives (libdispatch, Foundation, pthreads, etc.) for concurrency. Language support for concurrency is an often-requested and potentially high-value feature, but is too large to be in scope for Swift 3.0.
I guess this means no language-level "primitives" for threading are in the pipeline for the foreseeable future.
