I'm developing an augmented images app using ARKit. The images themselves are sourced online. The app is mostly done and working fine. However, I download the images the app will be tracking every time the app starts up. I'd like to avoid this by perhaps downloading the images and storing them to the device.
My concern is that as the number of images grow, the app would download too many images to the device. I'd like some thoughts on how to best approach this. For example, should I download and store some of the images in CoreData, or perhaps not store them at all?
