How to make a beautiful graph in Xcode?

Question

iOS

Good afternoon! it is necessary to dynamically (the data is updated directly in the program) draw a graph with points in Xcode. Let me remind you, I am a complete noob, I understand Swift for about three weeks at the most, and I ask you to poke my nose into the necessary tutorials :)
I don’t understand if this is drawn manually or there is some kind of library for this, or an object that I don’t see.
Thank you very much in advance!

The best chart on iOS is done using CorePlot:

Charts is also good, but it was not enough for me
