[GSoC 2017] Porting Swift to Haiku - Final Report | Haiku Project

[Haiku]

Hello everyone!

This blog-post marks the final report on bringing Swift to Haiku in the Google Summer of Code period. My introductory post on this project can be found here for a brief overview of the project.

Then now we can start to compile something like this ? https://github.com/aslanyanhaik/youtube-iOS or it is hard?

Only the programming language was ported, not the whole libraries from iOS.
So for now it will be restricted to comand-line apps. Maybe latter on graphics apps, but using Haiku’s native widgets.

I don’t even know if the GUI toolkit from iOS has an open source implementation?

You wouldn’t be able to compile applications/libraries made specifically for Apple platforms using open-source Swift. They use libraries such as Cocoa, UIKit, etc which are only available on Apple platforms.

@PulkoMandy I think cocotron aims to be the open-source reimplementation of the Cocoa APIs. However it uses the Objective-C runtime, so that won’t be useful for the Swift port anyway.

Also, open-source Swift has no way of directly calling C++ code, so you can’t use the Haiku APIs without some sort of C interface to them, like libcharlemagne or Habid.

Although these libraries are very outdated, the former did have a working demo of calling the Haiku API from C and then to Lua.

Update: the swift 3.1 recipe is now merged: https://github.com/haikuports/haikuports/commit/110f53039399ac3f06a3bcf0e5dd179445e68835

There is an open source implementation of UIKit and other iOS libraries, based on SDL and Cairo.
