The next version of Apple's operating system, iOS 12, will have news in the Photos application.
"For You" It is an application similar to the function that we have in Apple Music. They are recommendations on our photos like those that our contacts have shared with us. In it we can see: memories, Live Photos, or small videos among others. For You will also suggest what kind of tools you can use with an image.
On the other hand, Suggestions is a tool that will suggest people with whom you predictably want to share photos.
