Convert String from JSON to UIImage - ios

Question

I'm receiving some JSON data from a webservice, which includes an image represented as a Sting.
How can I convert this string into an image?
The JSON data is in an NSDictionary, and the Image data is the Object form the "Content"-key:
if let newBannerContentString = newBanner.objectForKey("Content") as? String {
let someImage = UIImage(contentsOfFile: newBannerContentString)
}
This returns nil to someImage.

If string is base64 encoded you could create NSData from that string and image from that data.
if let newBannerContentString = newBanner.objectForKey("Content") as? String {
let data = NSData(base64EncodedString: newBannerContentString, options: NSDataBase64DecodingOptions.IgnoreUnknownCharacters);
let someImage = UIImage(data: data!);
}
