==(_:_:)

Returns a Boolean value indicating whether the two given values are equal.

Available because Self conforms to BinaryInteger.

static func == <Other>(lhs: Self, rhs: Other) -> Bool where Other : BinaryInteger

Parameters

lhs: An integer to compare.
rhs: Another integer to compare.

Overview

You can check the equality of instances of any BinaryInteger types using the equal-to operator (==). For example, you can test whether the first UInt8 value in a string’s UTF-8 encoding is equal to the first UInt32 value in its Unicode scalar view:

let gameName = "Red Light, Green Light"
if let firstUTF8 = gameName.utf8.first,
    let firstScalar = gameName.unicodeScalars.first?.value {
    print("First code values are equal: \(firstUTF8 == firstScalar)")
}
// Prints "First code values are equal: true"
