Ios swift - storing uiimage in document directory and path in core data

I'm currently storing my images directly in core data and experiencing issues when having to retrieve a high quality images.

I was advised to store the images in the document directory and save a path in core-data as to not store the actual images there but simply the address of where I can go and find it.

Can someone push me in the right direction? Can't seem to find the appropriate guidance?

Save an image in Document directory is easy this code is not optimized is just for give you a hint( you should manage errors, optionals etc). Suppose that you already have a valid UIImage instance called image and a valid image name String called imageName

                let data = UIImagePNGRepresentation(image)
                // Unwrapping the data optional
                if let data = data {
                    let paths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)
                    let path = (paths.first! as! NSString).stringByAppendingPathComponent(imageName)
                    data.writeToFile(path, options: [])
                  //Save the path into your managed object
                    }

Try Hanake cache: https://github.com/Haneke/Haneke It worked really well for me personally with the same problem. It makes a sometimes painful task pretty easy.
