Error: Unsupported model type: gemma3n

[seungjun-green]

If I try to use gemma-3n model using swift-mlx-examples package I get following error:

Error: Unsupported model type: gemma3n

I installed the package and run the code with below simple code. It all worked well with different version of model such as SmolLM-135M-Instruct-4bit but keep failing when I try to use mlx-community/gemma-3n-E2B-it-lm-bf16 or mlx-community/gemma-3n-E4B-it-lm-bf16

import SwiftUI
import MLXVLM
import MLXLMCommon

struct ContentView: View {
    @State private var isLoading = false

    var body: some View {
        VStack(spacing: 20) {
            if isLoading {
                ProgressView("Processing...")
            }

            Button("Process") {
                Task {
                    await process()
                }
            }
            .padding()
        }
        .padding()
    }

    func process() async {
        isLoading = true
        defer { isLoading = false }

        do {
            let model = try await loadModel(id: "mlx-community/SmolLM-135M-Instruct-4bit")
            let session = ChatSession(model)
            
            print(try await session.respond(to: "What are two things to see in San Francisco?"))

        } catch {
            print("Error: \(error.localizedDescription)")
        }
    }
}
