I need your help to convert this Python script to Swift:

startcmd = b'0s000000000000000000'
data = NSData.dataWithBytes_length_(self.startcmd, len(self.startcmd))

Indeed, I wrote this but I know ... I am wrong:

let bytes : [UInt8] = [ 0x0, 0x73, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0 ]
let data = Data(bytes:bytes)

  • your code looks correct. note the the bytes keyword can be omitted Data(bytes) Commented Feb 19, 2019 at 5:21
  • Note that if startcmd is a string the printable digit character 0, ASCII value is 0x30same as 48 not 0x0 Commented Feb 19, 2019 at 5:25
  • let bytes: [UInt8] = [48, 115, 48, 48, 48, 48, 48, 48, 48, 48, 48, 48, 48, 48, 48, 48, 48, 48, 48, 48] String(data: Data(bytes), encoding: .ascii)! // "0s000000000000000000" Commented Feb 19, 2019 at 5:30
  • @Leo Dabus : Thank you so much for you help. Can you correct me. 1) I need to explod the string to get a array? 2) I need to loop the array and convert character to ASCII value? Thank you so much for your help. ^^ Commented Feb 20, 2019 at 7:03
