^ operator in Swift

Looking through the hashable protocol, and to make a matrix location struct to conform:

struct MatrixLocation: Hashable {
    let row: Int
    let col: Int
    var hashValue: Int { return row.hashValue ^ col.hashValue }
}

The hash value has the ^ operator.

What is the ^ operator in Swift?

^ is the XOR operator in Swift. Basically it compares the bits of the two operands, and for each bit, it sets the corresponding bit of the result to 1 if one of the two input bits is 1, but the other is 0. If both bits are 1 or both bits are 0, it sets the bit in the result to 0.

So if you have 0x49 ^ 0x13, that would be 01001001 XOR 00010011, which would come out to 01011010, or 0x5a.
