Swift base64 decoding returns nil

Question

I am trying to decode a base64 string to an image in Swift using the following code:

let decodedData=NSData(base64EncodedString: encodedImageData, options: N         


        

Answer 1

It's make problem with special character, but an interesting point is if we use NSData and NSString then it's working fine.

static func decodeBase64(input: String)->String{
        let base64Decoded = NSData(base64Encoded: input, options:   NSData.Base64DecodingOptions(rawValue: 0))
            .map({ NSString(data: $0 as Data, encoding: String.Encoding.utf8.rawValue) })

        return base64Decoded!! as String
}
