# .!=(_:_:) Pointwise compare not equal to. ``` static func .!= (a: SIMD64, b: SIMD64) -> SIMDMask.MaskStorage> ``` ## Discussion Each lane of the result is true if that lane of a is not equal to the corresponding lane of b, and false otherwise. Equivalent to: ``` var result = SIMDMask() for i in 0..<64 { result[i] = (a[i] != b[i]) } ``` --- Copyright © 2026 Apple Inc.
