# isNotEqual(to:)

Returns a Boolean value that indicates whether the receiver is not equal to another given object.

## Declaration

```swift
func isNotEqual(to object: Any?) -> Bool
```

## Parameters

- `object`: The object with which to compare the receiver.

## Return Value

Return Value YES if the receiver is not equal to object, otherwise NO.

## Discussion

Discussion Currently, isNotEqual(to:) messages are never sent to any object from within Cocoa itself. The default implementation for this method provided by NSObject method returns YES if an isEqual: message sent to the same object would return NO.
