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

Question

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?

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.

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
                    }
