# MLCLayer

The base class for all framework layers.

## Declaration

```swift
class MLCLayer
```

## Overview

Overview This class defines a polymorphic interface for MLCLayer subclasses. There are subclasses for each supported neural network layer type. Use the appropriate subclass initializer to create a layer object.
