Linker Error while using Vapor inside XCode Project

Linker Error while using Vapor inside XCode Project

nishant-dani opened this issue 5 months ago · 6 comments

I am linking with the Vapor library pulling in the package through Package Dependencies in xcode Project, and then in my Target I link Binary with Libraries I am linking with Vapor. Vapor itself pulls in a lot of Swift packages including AsyncHTTPClient which in turn uses SwiftNIO. Somewhere along the build process, I am getting linker error and it fails to build AsynchHTTPClient and then in turn fails to build Vapor. Any tips on how I might figure this out?

What version of Xcode and Swift? You might have to raise an issue on AsyncHTTPClient since this looks like an error in that repo

Answer 2 · 2023-12-19T21:02:24.000Z

XCode version is Version 15.0.1 (15A507).
swift-driver version: 1.87.1 Apple Swift version 5.9 (swiftlang-5.9.0.128.108 clang-1500.0.40.1)
Target: x86_64-apple-macosx13.0

Strangely enough the issue only shows up on the test Target, when it is it is importing XCTVapor. I looked into xcode and for the regular build it compiles using builtin-Swift-Compilation. However for the test Target it uses ld (linker) where the error shows up. It is not clear why xcode would have a different compilation process for the two Targets, and I have exhaustively compared the build settings.

I will however raise the issue on AsyncHTTPClient.

Oh, if it's about the test target, then it's actually a bug in SPM in Swift 5.9. I don't know if it's been fixed or not with Swift 5.9.2, but you could either try upgrading to Xcode 15.1, or apply a workaround in your Package.swift: duplicate all dependencies of your App target under the test target as well.

See here for an example, plucked from Duckie on the Discord server:

Answer 4 · 2023-12-20T17:23:30.000Z

I solved it just now by patching the package for AsyncHTTPClient to include the following line in dependencies in Package.swift. .product(name: "NIOTLS", package: "swift-nio"), I am able to get by without duplicating the dependencies in my Test Bundle. Possibly swift/xcode already solved the bug that you mentioned above, but when the package is deep down it still has a different bug again while building the Test Bundle. I have raised the issue with AsyncHTTPClient letting them know the workaround to verify if it is the right approach.

Referencing the issue on the AsynchHTTPClient. swift-server/async-http-client#721 They recognized that they had a missing dependency and requested a PR.
