==(_:_:)
Returns a Boolean value indicating whether the two given values are equal.

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"
