# ^=(_:_:)

Stores the result of performing a bitwise XOR operation on the two given values in the left-hand-side variable.

## Declaration

```swift
static func ^= (lhs: inout Int32, rhs: Int32)
```

## Parameters

- `lhs`: An integer value.
- `rhs`: Another integer value.

## Discussion

Discussion A bitwise XOR operation, also known as an exclusive OR operation, results in a value that has each bit set to 1 where one or the other but not both of its arguments had that bit set to 1. For example: var x: UInt8 = 5          // 0b00000101 let y: UInt8 = 14         // 0b00001110 x ^= y                    // 0b00001011
