Exhausted attempts to resolve the dependencies graph

[TofPlay]

It’s a great idea to have created this package.
I tried testing it by installing it as follows:

    dependencies: [
        .package(
            url: "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/mattt/AnyLanguageModel.git",
            exact: "0.7.1",
            traits: ["MLX","Llama"] // Enable MLX and Llama support
        )
    ],

It gave me the error:

exhausted attempts to resolve the dependencies graph, with the following dependencies unresolved:
* 'llama.swift' from https://github.com/mattt/llama.swift
* 'mlx-swift-lm' from https://github.com/ml-explore/mlx-swift-lm

Do I need to install other packages in addition to AnyLanguageModel?

My config: macOS 26.3, Xcode Version 26.2 (17C52)

@TofPlay Hmm, that should work as advertised. Is there any more output to share?

The full package.swift:

// swift-tools-version: 6.2
// The swift-tools-version declares the minimum version of Swift required to build this package.

import PackageDescription

let package = Package(
    name: "TPackages",
    products: [
        // Products define the executables and libraries a package produces, making them visible to other packages.
        .library(
            name: "TPackages",
            targets: ["TPackages"]
        ),
    ],
    dependencies: [

            traits: ["MLX", "Llama"] // Enable MLX and Llama support
        )
    ],
    targets: [
        // Targets are the basic building blocks of a package, defining a module or a test suite.
        // Targets can depend on other targets in this package and products from dependencies.
        .target(
            name: "TPackages",
            dependencies: [
                .product(name: "AnyLanguageModel", package: "AnyLanguageModel"),
            ]
        ),
        .testTarget(
            name: "TPackagesTests",
            dependencies: [
                .product(name: "AnyLanguageModel", package: "AnyLanguageModel")
            ]
        ),
    ]
)

@TofPlay It looks like this is a known bug in Swift Package Manager swiftlang/swift-package-manager#9286

You can resolve the problem by explicitly listing the dependencies required for those traits. So in your case:

    dependencies: [
        .package(
            url: "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/mattt/AnyLanguageModel.git",
            exact: "0.7.1",
            traits: ["MLX", "Llama"] // Enable MLX and Llama support
        )
+       .package(
+           url: "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/mattt/llama.swift", from: "2.0.0"),
+       .package(
+           url: "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/ml-explore/mlx-swift-lm", .upToNextMajor(from: "2.7484.0")),
    ],

@TofPlay I just merged #136, which updates the README to document this workaround. Please let me know if you're still having problems with this, or hit any other snags.
