# !=(_:_:) Returns a Boolean value indicating whether the two given values are not equal. ``` static func != (lhs: Self, rhs: Other) -> Bool where Other : BinaryInteger ``` ## Parameters `lhs` An integer to compare. `rhs` Another integer to compare. ## Discussion You can check the inequality of instances of any `BinaryInteger` types using the not-equal-to operator (`!=`). For example, you can test whether the first `UInt8` value in a string’s UTF-8 encoding is not 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 different: \(firstUTF8 != firstScalar)") } // Prints "First code values are different: false" ``` --- Copyright © 2026 Apple Inc.
