# progress

A value that indicates how much of the file has been downloaded.

## Declaration

```swift
var progress: Float { get }
```

## Mentioned in

Unlocking purchased content

## Discussion

Discussion The value of this property is a floating point number between 0.0 and 1.0, inclusive, where 0.0 means no data has been download and 1.0 means all the data has been downloaded. Typically, your app uses the value of this property to update a user interface element, such as a progress bar, that displays how much of the file has been downloaded. Do not use the value of this property to determine whether the download has completed. Instead, use the downloadState property.
