How do you convert a uuid_t tuple to an UnsafeMutablePointer<UInt8>?

Using Swift

I'm prettty sure this is safe, though admittedly I'm never 100% certain when to use withMemoryRebound(to:) and friends. @Andrew_Trick can probably confirm or deny:

import Foundation

var uuid = UUID().uuid

withUnsafeMutablePointer(to: &uuid) { tuplePointer in
 tuplePointer.withMemoryRebound(to: UInt8.self, capacity: 1) { pointer in
   uuid_generate(pointer)
 }
}

(I used uuid_generate in my example instead of your Obj-C API in order to have a self-contained example for testing.)
