# projectExtensionData

Compressed project-specific data to use in the change request.

## Declaration

```swift
var projectExtensionData: Data { get set }
```

## Discussion

Discussion The total size of stored data is limited to 5 MB; attempting to store more data will result in an error. Don’t include rasterized images that can be locally cached. Limit stored data to compressed project-specific data.
