This is how I encoded:

let url:NSURL = NSURL(string : pictURL)!
let imageData : NSData = NSData.init(contentsOf: url as URL)!
let str64 = imageData.base64EncodedData(options: .lineLength64Characters)
// next line my code to save in core data just ignore it

The value for encoded data = 3286 bytes. I think it is wrong

let pictEncoded = person.value(forKeyPath: "pictureurl") as! String

if let imageData = Data(base64Encoded: pictEncoded, options: .ignoreUnknownCharacters),
       let image = UIImage(data: imageData)
    {
        cell.imgView.image = image
    }

@LeoDabus: Value of optional type 'Data?' not unwrapped; did you mean to use '!' or '?'? ....... i tried to fix it but it crashes – ibmot Dec 07 '16 at 03:38
You need to show how you are encoding it – Leo Dabus Dec 07 '16 at 03:47
Are you sure that pictureurl is an encoded image string and not an URL absolute string? – Leo Dabus Dec 07 '16 at 03:51

you have to drop the NS prefix from NSURL and NSData – Leo Dabus Dec 07 '16 at 04:07
