Implementing an Augmented Reality gallery

Creating an excellent AR experience has been made a lot simpler with the great features that exist in ARKit. However, there are still several things to keep in mind if you want to build an AR experience that users will love.

Certain conditions, such as lighting, the environment, and even what the user is doing, can have an impact on the AR experience. In this section, you will implement an AR gallery, and you will discover firsthand how ARKit is both amazingly awesome and sometimes a little bit fragile.

First, you'll set up a session in ARKit so you can implement image tracking to discover certain predefined images in the world, and you'll show some text above the found picture. Then, you'll implement another feature that allows users to place art from a gallery in the app in their own room.
