==(_:_:)
Returns a Boolean value indicating whether the corresponding components of two tuples are equal.
Declaration
func == <A, B, C, D>(lhs: (A, B, C, D), rhs: (A, B, C, D)) -> Bool where A : Equatable, B : Equatable, C : Equatable, D : EquatableParameters
- lhs:
A tuple of
Equatableelements. - rhs:
Another tuple of elements of the same type as
lhs.
Discussion
For two tuples to compare as equal, each corresponding pair of components must be equal. The following example compares tuples made up of 4 components:
let a = ("a", 1, 2, 3)
let b = ("a", 1, 2, 3)
print(a == b)
// Prints "true"
let c = ("a", 1, 2, 4)
print(a == c)
// Prints "false"
