Convert Data to Int64

Question

Is there a way to convert Data directly into Int64?

My solution is to convert Data -> String and then String -> Int64

let data = "123456".data(using: .utf8)! // data from string for example purposes


let idString = String(data: data, encoding: .utf8)! //IUO for example purposes too
let id = Int64(idString)

What does the data contain? A *string* representation (as in your example) or a *binary* representation of the number? — Martin R, Jun 12 '19 at 08:10

have you tried with

let int64Value = data.withUnsafeBytes {
    $0.load(as: Int64.self)
}
