round trip Swift number types to/from Data

Question

With Swift 3 leaning towards Data instead of [UInt8], I\'m trying to ferret out what the most efficient/idiomatic way to encode/decode swifts vario

Answer 1

You can get an unsafe pointer to mutable objects by using withUnsafePointer:

withUnsafePointer(&input) { /* $0 is your pointer */ }

I don't know of a way to get one for immutable objects, because the inout operator only works on mutable objects.

This is demonstrated in the answer that you've linked to.
