# OCKTaskViewController

An abstract superclass to all synchronized view controllers, that displays a task and its events.

## Declaration

```swift
class OCKTaskViewController<Controller, ViewSynchronizer> where Controller : OCKTaskControllerProtocol, ViewSynchronizer : OCKTaskViewSynchronizerProtocol
```

## Overview

Overview This abstract superclass has a factory function that you can use to conveniently initialize a concreted subclass.
