ios - 将数据转换为 Int64

Question

有没有办法将Data直接转换为Int64？

我的解决方案是转换 Data -> String 然后 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)

你尝试过

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