Answer 1

Above solution is working for me, I converted into swift3

Here you can find swift3 code

var base64Str = arr[1] as String
if base64Str.characters.count % 4 != 0 {
    let padlen = 4 - base64Str.characters.count % 4      
    base64Str += String(repeating: "=", count: padlen)
}

if let data = Data(base64Encoded: base64Str, options: []),
    let str = String(data: data, encoding: String.Encoding.utf8) {
        print(str)
}
