When working with the Core ML Tools package in Chapters 5, Emotion Detection with CNNs, and Chapter 6, Creating Art with Style Transfer, to convert a Keras model to Core ML, we saw how we could explicitly set the metadata, which is shown in Xcode. Create ML provides a way of explicitly setting this data by passing in an instance of MLModelMetadata when exporting the model. It provides you all the metadata we had seen when working with the Core ML Tools package, such as name, description and so on.
