MLXLanguageModel - Cannot find several methods in scope

[ivangalkindeveloper]

Hello!
Here is problem with finding several methods for MLX in last release

[ivangalkindeveloper]

I tried running MLXLanguageModel tests with a fork - they passed successfully, until I realized why there was a problem with the methods

Thanks for reporting, @ivangalkindeveloper. I'm sorry that's broken; I'm not sure what happened there. I was just able to verify this locally, and am working on a fix.

I'll add:

1. The problem also plays out in the HuggingChat example.
2. The package can be correctly connected if the dependencies on mlx-swift-lm are explicitly specified in the proxied package, example:

import PackageDescription

let package = Package(
    name: "HuggingChatKit",
    platforms: [
        .macOS(.v14),
        .iOS(.v17),
        .visionOS(.v1),
    ],
    products: [
        // Shims the AnyLanguageModel package with MLX support enabled
        .library(
            name: "HuggingChatKit",
            targets: ["HuggingChatKit"]
        )
    ],
    dependencies: [
        .package(
            url: "https://github.com/mattt/AnyLanguageModel.git",
            from: "0.5.1",
            traits: [
                .trait(name: "MLX"),
            ]
        ),
        .package(
            url: "https://github.com/ml-explore/mlx-swift-lm",
            branch: "main"
        )
    ],
    targets: [
        .target(
            name: "HuggingChatKit",
            dependencies: [
                .product(name: "AnyLanguageModel", package: "AnyLanguageModel"),
                .product(
                    name: "MLXLLM",
                    package: "mlx-swift-lm",
                    condition: .when(platforms: [.macOS, .iOS, .visionOS])
                ),
                .product(
                    name: "MLXVLM",
                    package: "mlx-swift-lm",
                    condition: .when(platforms: [.macOS, .iOS, .visionOS])
                ),
                .product(
                    name: "MLXLMCommon",
                    package: "mlx-swift-lm",
                    condition: .when(platforms: [.macOS, .iOS, .visionOS])
                )
            ]
        )
    ]
)

Otherwise, there will be a dependency resolution problem.
I think this needs to be clearly stated in the documentation and the example updated.

I meet the same issue while switch from my fork back to main repo. It's so weird. And I believe this issue is caused by my pr #64.

But it works perfectly in my fork XMLHexagram@5a8a799. And @mattt only add some test. I couldn't understand wt caused this issue.

[XMLHexagram]

Oh, I know wt happened. #66 broken #64... 😭

[XMLHexagram]

@mattt I create PR #71 to address this issue.

[noorbhatia]

@mattt @XMLHexagram I had already pushed a PR #67 after the release

[mattt]

Thank you all for your patience. I just merged #67 and cut a new 0.5.2 release. Please update to that and let me know if you're still seeing this problem.
