# WKExtendedRuntimeSessionErrorCode.barDisabled

The user has disabled background app refresh.

## Declaration

```swift
case barDisabled
```

## Discussion

Discussion If the user has disabled Background App Refresh for this app, any attempt to schedule a session by calling the start(at:) method fails. The system calls your delegate’s extendedRuntimeSession(_:didInvalidateWith:error:) method and passes a WKExtendedRuntimeSessionInvalidationReason.error reason with a WKExtendedRuntimeSessionErrorCode.barDisabled error. Users can turn off Background App Refresh by selecting General > Background App Refresh in the Watch App.
