# progress

A measure of progress through the task, given as a fraction in the range [0, 1].

```
var progress: Double { get set }
```

## Discussion

It’s up to you to define what progress means for each task in your app. For example, you might define progress through a quiz context as the fraction of questions answered. You could report the progress through a video context as a fraction representing the number of minutes watched out of the total minutes in the video.
