 Randy Eckenrode | I guess Swift may slip to post 26.05, unfortunately. | 14:11:35 |
| Randy Eckenrode | Biggest help for Swift right now would be using my branch to build things and find problems. That’s how the issue with in-tree SwiftPM dependencies was uncovered. | 14:13:02 |

| Randy Eckenrode | Did the Git error just
hit CI? | 14:27:43 |
| Randy Eckenrode | No, GitHub appears to be having issues. | 14:29:58 |

 viraptor | Looks like that's my next blocker. I'm stuck on failed to build module 'Swift'; this SDK is not supported by the compiler (the SDK is built with 'Apple Swift version 5.10 (swiftlang-5.10.0.12.5 clang-1500.3.9.1.1)', while this compiler is 'Swift version 6.2.4 (swift-6.2.4-RELEASE)') currently. But at least I've got all the other required changes to merge in the meantime. | 23:25:48 |
| Randy Eckenrode | Is that using the current Swift? | 23:44:14 |

| viraptor | I'll check today if anything changed post-rebase. | 23:47:54 |

(all the changes are "YOLO, just make it work" level, it will be cleaned up a lot before submitting anywhere) | 00:25:30 |
| Randy Eckenrode | Is it using the wrong SDK? Swift is really sensitive to SDK version. | 00:44:29 |
| Randy Eckenrode | It should be propagating the 26.x SDK though. | 00:44:38 |
| viraptor | Hmm... probably. | 00:50:26 |
|  picnoir changed their display name from Picnoir to picnoir. | 10:06:11 |
| viraptor | It seems like using apple-sdk_26 solved some errors. But now I'm stuck with SwiftShims module missing, which should be loaded from Swift's stdlib, but even putting swiftPackages.stdlib explicitly in nativeBuildInputs doesn't help. I get lots of:
Swift.swiftmodule/x86_64-apple-macos.swiftinterface:5:8: error: Unable to find module dependency: 'SwiftShims'
Grepping that string in the stdlib package doesn't bring up anything, so I'm suspicious of everything now. | 11:40:04 |
| Randy Eckenrode | This is also failing in Hammerspoon’s build or in the Swift build itself? | 11:42:09 |
| Randy Eckenrode | The latter should work. I’ve been building .NET and mpv with it locally. | 11:42:52 |
| Randy Eckenrode | Well, until nodejs-slim got totally broken. | 11:43:30 |
| viraptor | hammerspoon build. Swift worked fine. | 11:43:37 |
| viraptor | ah! there's something in stdlib.dev - I missed it, maybe I'll be lucky :) | 11:44:41 |
| viraptor | I was not lucky... stdlib.dev does indeed contain SwiftShim, but it's not found. Unfortunately I know nothing about Swift module lookup system. I'll do some reading unless you know the answer immediately.

import SwiftShims | 11:49:40 |
| Randy Eckenrode | Are you using swiftPackages.swift or .swiftc? | 11:51:21 |
| Randy Eckenrode | That SDK path is odd. | 11:52:13 |
| viraptor | .swiftc - I think it's working better now with .swift! thank you. | 11:53:14 |
| viraptor | 🎉 it did work. | 11:53:57 |
| Randy Eckenrode | The stdlib is separated from the compiler. .swift sets up a symlink farm with the stdlib, compiler, and other needed dependencies. | 11:54:22 |
| Randy Eckenrode | Like on Linux it will include Foundation. | 11:54:34 |
| Randy Eckenrode | Nix makes building multiple packages from one source an enormous pain in the ass, but we want these separate so you don’t pull in the full Swift closure just for linking to its stdlib (and for cross eventually). | 11:55:40 |
