# backgroundTimeRemaining

The maximum amount of time remaining for the app to run in the background.

## Declaration

```swift
nonisolated var backgroundTimeRemaining: TimeInterval { get }
```

## Mentioned in

Extending your app’s background execution time

## Discussion

Discussion The value is valid only after the app enters the background and has started at least one task using beginBackgroundTask(expirationHandler:) in the foreground. System conditions may end background execution earlier, either by calling the expiration handler, or by terminating the app. This method can be safely called on a non-main thread.
