Swift Base64 Format

Question

On this website, for example when you drop in an image, it is turned into a proper base64 format: http://base64image.org/

In my Swift app, here is what I have to generate a base64 string from an image:

let image_Data = UIImagePNGRepresentation(default_image)
let base64String = image_Data!.base64EncodedStringWithOptions(.Encoding64CharacterLineLength)

This gives me something similar, but it has spaces and line breaks. How do I get an output just like the output from the website above?

Include some sample output from the code and the website for the same image so we can see the difference and understand your problem — luk2302, Dec 21 '15 at 23:22

let image_Data = UIImagePNGRepresentation(default_image)
let base64String = image_Data!.base64EncodedStringWithOptions([]) // Don't ask for line breaks

If you remove the request for line breaks, does it match what you're expecting?

Thank you! This gives me the error: "Missing argument for parameter #1 in call" – Katie H Dec 21 '15 at 23:27

.base64EncodedStringWithOptions([]) or .base64EncodedStringWithOptions(NSDataBase64EncodingOptions()) – Leo Dabus Dec 21 '15 at 23:50
Fixed based on @LeoDabus's comment. – Rob Napier Dec 22 '15 at 14:22
@Kaptain I don't understand the question. This is Swift. – Rob Napier Jan 04 '17 at 19:21
