The biggest update to Photos in iOS 12 is a brand new tab called For You. The For You tab combines Memories and iCloud Shared Albums. It will also help you share your photos with friends, family and on social media. Sharing suggestions show up right at the top of the For You section. But Apple is taking sharing a step further. When you receive shared photos, you will also be prompted to send back any photos you have that are from the same event, time or location.
