Array -> UnsafeMutablePointer -> Array

Array -> UnsafeMutablePointer -> Array

var initalArray = [1, 2, 3]
let pointer: UnsafeMutablePointer<Int> = UnsafeMutablePointer(initalArray)
let arrary = Array(UnsafeBufferPointer(start: pointer, count: initalArray.count))

Shouldn't this be:

let pointer: UnsafeMutablePointer< Int > = UnsafeMutablePointer(&initalArray)

with the '&'

@capnslipp It work because a "Float" or "Int" array is also a ContiguousArray
Some me memory of this array is stored continuously
For more detail please see Apple Documentation

Hi, according to Apple's document:

The pointer created through implicit bridging of an instance or of an array’s elements is only valid during the execution of the called function. Escaping the pointer to use after the execution of the function is undefined behavior. In particular, do not use implicit bridging when calling an UnsafeMutablePointer initializer.

so, using pointer from

// Swift 3.0 Line 2
let pointer: UnsafeMutablePointer = UnsafeMutablePointer(mutating: initalArray)

is undefined.
