Xcode version

Facebook iOS SDK version

16.1.3

Dependency Manager

SPM

SDK Framework

Core

Goals

Get rid of linker warnings

Expected results

No linker warings

Actual results

Ignoring duplicate libraries: '-lc++', '-lz'

Steps to reproduce

Please find the sample project attached. SampleApp.zip

Xcode 15 beta 7. App that links with 'z' and 'c++' libraries. Integrate the latest Facebook SDK using SPM.

This setup results in linker waring: Ignoring duplicate libraries: '-lc++', '-lz'

The issues is that linkerSettings used in Package.swift and the existing project settings produce duplicate '-lc++' and '-lz' with .

extension LinkerSetting {
    static let cPlusPlusLibrary = linkedLibrary("c++")
    static let zLibrary = linkedLibrary("z")
    static let accelerateFramework = linkedFramework("Accelerate")
}

...

static let core = target(
        name: .core,
        dependencies: [.aem, .Prefixed.basics, .Prefixed.core],
        linkerSettings: [
            .cPlusPlusLibrary,
            .zLibrary,
            .accelerateFramework,
        ]
)

This sounds more like the issue for Apple, and I've file one. But maybe you would consider removing these linkerSettings? I understand that this might be not that easy:

• clients will have to link with the necessary SDK dependencies themselves
• one possible solution is to specify the type of the library produced by the package, so that it will be dynamic framework that links with it's own dependencies

Now that Xcode 15 is officially released can you give an ETA when this will be fixed?
