Problem bumping to 0.3.2 about swiftsemantics HOT 6 CLOSED

@cflorion Thanks for the kind words!

The issue you're running into stems from a limitation in how Swift Package Manager resolves transitive dependencies. Because SwiftSemantics depends on an exact version of swift-syntax, you can't depend on SwiftSemantics with a non-exact requirement.

The installation instructions in the README should work (if they don't, please let me know!) https://github.com/SwiftDocOrg/SwiftSemantics#installation

@mattt I can still reproduce. I'm using Xcode built-in Swift Package Managing function instead of editing Package.swift. So I just set like this 👇

But I got this 👇

I think we should change .revision("release/5.4")) into .exact("some.stable.version") to fix this problem.
PS. I tried to integrate by branch: main. I got passed. But I don't think it was a good solution :(

I think the point is that:
...but 'swiftsemantics' depends on an unstable-version package 'swift-syntax' ?

Because in [email protected],

    dependencies: [
        .package(name: "SwiftSyntax",
                 url: "https://github.com/apple/swift-syntax.git",
                 .revision("release/5.4")),
    ],

I'm using Xcode 12.5 which integrated Swift 5.4. I can still reproduce this problem.

@wgy6055 That's right, you'd need to specify an exact version of SwiftSemantics, too. I had that wrong in the README, but just updated it. Can you still reproduce with the latest instructions?

// swift-tools-version:5.3

import PackageDescription

let package = Package(
  name: "YourProject",
  dependencies: [
    .package(
        name: "SwiftSemantics",
        url: "https://github.com/SwiftDocOrg/SwiftSemantics",
        .exact("0.3.2")
    ),
    .package(name: "SwiftSyntax",
         url: "https://github.com/apple/swift-syntax.git",
         .revision("release/5.4")),
  ]
)

I too had to target "main" to add the package dependency as my source code doesn't live at the root of the repo and thus Package.swift doesn't work. Everything builds fine, but any time I try to run the project, I get a runtime error:

dyld: Library not loaded: @rpath/lib_InternalSwiftSyntaxParser.dylib
  Referenced from: ...
  Reason: image not found

@tjprescott
I found something from README of SwiftSyntax. I believe this is what you need.

SwiftSyntax depends on the lib_InternalSwiftSyntaxParser.dylib/.so library which provides a C interface to the underlying Swift C++ parser. When you do swift build SwiftSyntax links and uses the library included in the Swift toolchain. If you are building an application make sure to embed _InternalSwiftSyntaxParser as part of your application's libraries.
