NSData from UInt8

Question

I have recently found a source code in swift and I am trying to get it to objective-C. The one thing I was unable to understand is this:

var theData:UInt8!

         


        

Answer 1

In Swift 3

var myValue: UInt8 = 3 // This can't be let properties
let value = Data(bytes: &myValue, count: MemoryLayout.size)
