Swift Support

[cr4zyengineer]

Swift support is very complex as swift is huge in terms of compilation...

but the path is clear by now

Swift Source

We areeee getting somewhere, expect a massssiveee LLVM-On-iOS update

We areeee getting somewhere

Amazing and great work.

Is there a branch or ipa we can give some preview with? :)

no absolutely no, ive given up on adding swift support 7 times already, but I keep attempting it, same with LLDB, apple made it extremely difficult to use the Swift project in other projects, the only thing that is needed is the part of the swift compiler that compiles swift code down to SIL and SIL to LLVM IR, LLVM IR can then be compiled by the rest of the LLVM project that already exists within Nyxian.

A tip:

Seems you use LLVM to build a IR interpreter. Which I used internally in my project.

Our LLVM on iOS just use the cmake native toolchain with little modifications: https://github.com/leetal/ios-cmake/blob/master/README.md

And runs LLVM 18. Which can successfully interpret Swift 6.3 compiler generated IR

[cr4zyengineer]

Do you think im an idiot?? Pull your ass IR interpreter into your own asshole, IR interpretation is not what we use, we compile to machine code and execute, IR interpretation is ass slow

[cr4zyengineer]

I have my own LLVM fork and I have my own patched and I run LLVM 19 all FOSS

[dreampiggy]

Oh, seems I misunderstood the architecture. This is a native code execution which requires JIT and half jailed iOS devices. Sorry to bother

[cr4zyengineer]

I solely mean compiling LLVM IR down to machine code, which works, Nyxian is able to compile in all C languages, so I just need the swift-frontend which compiles Swift down to SIL and SIL down to LLVM IR which can be compiled down to the lowest machine code for arm64

[cr4zyengineer]

No it does not require JIT

[cr4zyengineer]

It uses a technique apple cannot patch, it uses a unpatchable vulnerability in apples code signing philosophy that would break every already signed iOS app if they would attempt to patch it in the future... https://github.com/ProjectNyxian/Nyxian/blob/main/Nyxian/LindChain/LiveContainer/LCBootstrap.m#L173

You didnt bother really, what bothers me is someone confidently flying into the issues as if youd know better about Nyxian and totally miss how Nyxian works, thats what pisses me off... someone who tries to help without having read the source code in the slightest
