在Xcode12更新后在swift中运行MLModels时出现新错误

import coremltools as ct

# 加载旧模型
model = ct.models.MLModel('OldModel.mlmodel')

# 更新模型
updated_model = ct.convert(model, source='coreml')

# 保存更新后的模型
updated_model.save('UpdatedModel.mlmodel')

import CoreML

// 加载模型
guard let model = try? VNCoreMLModel(for: YourModel().model) else {
    fatalError("无法加载模型")
}

// 创建请求
let request = VNCoreMLRequest(model: model) { request, error in
    guard let results = request.results as? [VNClassificationObservation],
          let topResult = results.first else {
        print("无法获取结果")
        return
    }
    print("预测结果: \(topResult.identifier) 置信度: \(topResult.confidence)")
}

// 处理图像
if let image = UIImage(named: "yourImage.jpg") {
    let handler = VNImageRequestHandler(cgImage: image.cgImage!, options: [:])
    do {
        try handler.perform([request])
    } catch {
        print("处理图像时出错: \(error)")
    }
}
