How to convert UInt8 byte array to string in Swift

Question

I am facing problems while converting UInt8 Byte array to string in swift. I have searched and find a simple solution

String.stringWithBytes(buf         


        

Answer 1

You need convert Int8 array to Data firstly, then convert to String.

This is my solution:

    var buffer = [Int8](repeating: 0, count: 100)
    let data = Data(bytes: buffer as [Int8], count: buffer.count);
    return String( data: data, encoding: .utf8)

Answer 2

Swift 4 / Ubuntu 16.04

let serverAns = [UInt8](repeating: 0x50, count: 100)
let readBytes = 8
let truncatedServerAns = serverAns[0..<readBytes]
let tsaData = Data(bytes: truncatedServerAns)
let serverIdStr = String(data: tsaData, encoding: .utf8)
print("serverIdStr=\(String( describing: serverIdStr))")

// Prints:
// serverIdStr=Optional("PPPPPPPP")
