Answer 1

Do you need use the withUnsafeBufferPointer method from Array as

var alphaPtr: UnsafeBufferPointer = alpha.withUnsafeBufferPointer { $0 }

that's command produce a pointer optional if you need working with a specific type could you you use bindMemory(to:) or other function that match with you requirements.

Sometimes use a &alpha if you need a UnsafeRawPointer as a function parameter.
