How to convert binary code to text in Swift

Answer 1

import Foundation

func bin2text(_ binTxt: String) -> String {
    var text = ""

    // Iterate through the binary string in chunks of 8 bits
    for i in stride(from: 0, to: binTxt.count, by: 8) {
        // Extract an 8-bit chunk
        let startIndex = binTxt.index(binTxt.startIndex, offsetBy: i)
        let endIndex = binTxt.index(startIndex, offsetBy: 8)
        let binaryChunk = String(binTxt[startIndex..<endIndex])

        // Convert the binary chunk to an integer
        if let asciiValue = Int(binaryChunk, radix: 2) {
            // Convert the integer to a character and append to the result
            text += String(UnicodeScalar(asciiValue)!)
        }
    }

    return text
}

let binaryInput = "0101000001110010011011110110011101110010011000010110110101101101011010010110111001100111"

let textOutput = bin2text(binaryInput)

print(textOutput)
