hello. I am new to iOS development. I've been learning on my own for a couple of months now. I am starting my first app. I would like to add interactive graphs that are both beautiful, customizable to my design, and animated as the load and are interacted with. We've all seen wonderful graphs and controls like these. Here are some samples: [ OK, I can't include links because I have not had 10 posts yet. You know what these look like… Interactive animated graphs from Nike, mint, when they load they sort of grow from the bottom or wave in from the side. ] My question is, are these coded from scratch using Swift base capabilities or are these third-party plug-ins? Is it very difficult to program these? I would appreciate some insight Thank you!
