Unable to compile in SPM package

[ahtcx]

Hi.

I'm pretty new to Swift and the ecosystem so I don't have a great grasp on it all. I've been unable to use sharing-grdb in my SPM package (see error below). I came across swiftlang/swift#82529 which seems to be the same issue, does this mean it's a compiler bug and can't be fixed without a new Swift version?

The output below is with sharing-grdb@0.8.0 and swift@6.1.2 but I have tried with sharing-grdb@0.7.0 and Swift 6.0, 6.1.1, 6.1.2. Should I be using Swift 5?

Thanks!

Hi @ahtcx, as far as I know this only affects certain builds of Swift, in particular ones that have assertions enabled. I believe this is the case with swiftly toolchains, but if you use the toolchains that come with Xcode it works, and it works in other toolchains such as the Linux toolchains.

I really don't know what the correct answer is here, and the Swift forums post linked from the GitHub issue does not help things much either. On the one hand it would be nice for our library to build with assertions enabled, but on the other hand Swift has a lot of bugs that fail to compile perfectly fine Swift code. And parameter packs tend to push Swift to its limits more than other features, which StructuredQueries highly depends on.

Can you use the official Xcode toolchains instead of swiftly?

[ahtcx]

Thanks for getting back to me so fast. Since I'm using mise I ended up updating my mise.toml file so it uses the Xcode Swift toolchain and that resolved the compilation issues.

swift = [
	{ os = ["macos"], version = "path:/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swift" },
