# WKExtendedRuntimeSessionErrorCode.exceededResourceLimits

The session exceeded its resource limits.

## Declaration

```swift
case exceededResourceLimits
```

## Mentioned in

Using extended runtime sessions

## Discussion

Discussion During an extended runtime session, the system limits your app’s amortized CPU usage over time. If your app exceeds the limits during a 60-second window, the system cancels the session. Monitoring usage-per-minute allows your app to experience brief spikes of CPU usage, as long as the average remains low. When the system cancels your session, it calls your delegate’s extendedRuntimeSession(_:didInvalidateWith:error:) method and passes a WKExtendedRuntimeSessionInvalidationReason.error reason with a WKExtendedRuntimeSessionErrorCode.exceededResourceLimits error.
