For trivial data types (like UInt8) this will work, but if you want to follow the rules I recommend reading the following:

* UnsafeRawPointer Migration


* SE-0107 “UnsafeRawPointer API”


Spoiler: that’ll point you to `initialize(to:count:)` (-:

                   *                   *                   *

Also, why are you manually allocating this rather than using [UInt8]?  The latter is easier, safer, and likely to have similar levels of efficiency.
