I thought this would be the appropriate community to ask this question.
Back when Apple had their developer's conference over the summer, I was aware that they were going to make Swift open source.
I was under the impression that Xcode would not be ported to Linux, but I was under the understanding that some entity would create a development program to imitate Xcode.
Therefore, I am wondering about new developments in this situation.
Does anyone have any more current knowledge about this topic or any experiences with this?
There's a misunderstanding here.
Swift the programming language is open source.
It doesn't mean that iOS or OS X frameworks, like Cocoa, UIKit, etc, are available in Linux - Apple didn't announce that.
When you make an app for iOS using Swift, you have to import UIKit and other libraries - those are the iOS parts.
Swift is just the language - you can already make an iOS app with Ruby, Objective-C, JavaScript, etc, using these same libraries.
