如何将swift中的Int8转为Data

Question

Only examples I could find are about Uint8. How to convert Int8 to Data in Swift?

let int8Value: Int8 = -10
let data = int8Value.data // I need some extension like this

Answer 1

You can use this simple extension to achieve your desired output.

extension Int8{
    var data:Data? {
        return "\(self)".data(using: .utf8)
    }
}
