Swift 2 and Linux/OS X differences

Question

I'm trying to port some basic app from OS X to Linux but it seems that even basic stuff is missing on Linux platform. Is there some documentation what is missing ?? Here is example:

exmcast.swift:7:20: error: value of type 'String' has no member 'stringByReplacingOccurrencesOfString'
let name: String = address.stringByReplacingOccurrencesOfString(".", withString: "_")

This simple code works on OS X. On Linux - you see results. It's very hard to port anything when there is no basic info what is missing. And it looks like even basic stuff is missing..

Answer 1

Swift 3 will be released in fall 2016.

The recently open-sourced Swift and the Linux port are work in progress:

The port is still a work in progress but we’re happy to say that it is usable today for experimentation.

You can go to Swift.org and github.com/apple and enjoy the fantastic work.

When you find something not yet implemented, you can file a bug and/or help implement the feature.

New versions of the open source Swift will be posted regularly on Swift.org.
