print(a != c)
// Prints "true"

Parameters: lhs: A tuple of Equatable elements. rhs: Another tuple of elements of the same type as lhs.

Declaration

func != <T : Equatable where T : RawRepresentable, T.RawValue : Equatable>(_: T, rhs: T)

Returns a Boolean value indicating whether the two arguments are not equal.

Parameters: lhs: A raw-representable instance. rhs: A second raw-representable instance.

Declaration

func != <T : Equatable>(_: T, rhs: T)

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

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.

Parameters: lhs: A value to compare. rhs: Another value to compare.
