Instance Method

isEqual(to:)

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

Declaration

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

Parameters

object

The object with which to compare the receiver.

Return Value

true if the receiver is equal to object, otherwise false. In effect returns false if receiver is nil.

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 true if an isEqualTo: message sent to the same object would return true.
