Operator

!=(_:_:)

Returns a Boolean value indicating whether two values are not equal.

Declaration

static func != (lhs: Set<Element>, rhs: Set<Element>) -> Bool

Parameters

lhs

A value to compare.

rhs

Another value to compare.

Discussion

Inequality is the inverse of equality. For any values a and b, a != b implies that a == b is false.

This is the default implementation of the not-equal-to operator (!=) for any type that conforms to Equatable.
