如何在数组<UInt8>上执行XOR操作?

我正在尝试对数组执行XOR操作。

第一阵列

var first: Array<UInt8> = Array<UInt8>.init(hex: "4C50CF1C2E08")
//equals [76, 80, 207, 28, 46, 8]

第二阵列

var second: Array<UInt8> = Array<UInt8>.init(hex: "91517975190D")
//equals [145, 81, 121, 117, 25, 13, 206]

十六进制输出除外。对于上面的示例,它将是:

DD01B6693705

I am using the CryptoSwift Framework

Found the Doc for XOR.

But I am struggling even to convert by UInt8 Array to one variable which holds a UInt8 to perform the ^. I am grateful for any ideas and hints.
