Int16 to Byte array wrong array order swift 4

i am trying to convert a Int16 into [UInt8] like that:

var track:Int16 = 4
let trackData = Data(bytes: &track, count: 2)

but the result is 

[4, 0]

I was wondering if there is a way to get 

[0, 4]

So when I do :

let value = Int16(bigEndian: trackData.withUnsafeBytes { $0.pointee })

I would get 4 instead of 1024

it is not much a rocket-science but byteSwapped may do the job for you, like:

let value = Int16(bigEndian: trackData.withUnsafeBytes { $0.pointee }).byteSwapped

that would make the value 4 in your case.

NOTE: even Apple Docs does not say too much about this property (kinda self explanatory, to be honest), so just for the sake of completion, here comes the reference of byteSwapped.
