How to draw a tree in iOS?

Question

iOS

Tell. How is it possible in iOS, or by what means to depict a tree or a graph, with the ability to interact with its elements. Maybe use some library? I know how to build data and arrange. I didn't have to work with graphics. Approximately as in the image. But everything will be vertical
