# isEqual(to:)

Returns a Boolean value that indicates whether the receiver is equal to another given object.

## Declaration

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

## Parameters

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

## Return Value

Return Value YES if the receiver is equal to object, otherwise NO. In effect returns NO if receiver is nil.

## Discussion

Discussion During the evaluation of an NSWhoseSpecifier object that contains a test whose operator is NSEqualToComparison, an isEqual(to:) message may be sent to each potentially specified object, if neither the potentially specified object nor the object being tested against implements a scriptingIsEqual(to:) method. The default implementation for this method provided by NSObject returns YES if an isEqualTo: message sent to the same object would return YES.
