# currentMode

The receiver’s current input mode.

```
var currentMode: RunLoop.Mode? { get }
```

## Discussion

The receiver’s current input mode. This method returns the current input mode *only* while the receiver is running; otherwise, it returns `nil`.

The current mode is set by the methods that run the run loop, such as [`acceptInput(forMode:before:)`](/documentation/Foundation/RunLoop/acceptInput(forMode:before:)) and [`run(mode:before:)`](/documentation/Foundation/RunLoop/run(mode:before:)).

## See Also

[`run(until:)`](/documentation/Foundation/RunLoop/run(until:))

Runs the loop until the specified date, during which time it processes data from all attached input sources.

[`run()`](/documentation/Foundation/RunLoop/run())

Puts the receiver into a permanent loop, during which time it processes data from all attached input sources.
