Recently went through all of the WWDC 2019 topics on SwiftUI and machine learning, and they are all really great. Since all of my projects are in various stages, I’m going to take the time to convert them to SwiftUI. This should also help me to work through and get a better understanding of different programming paradigms such as protocol oriented programming.
As far as machine learning goes, this is definitely an adventure. I’m currently working through Fast.ai’s Practical Deep Learning for Coders, v3 and it’s simply amazing! Its a top to bottom teaching approach so you’ll learn how to do things first then theory. The DeepLearning.ai courses are more bottom up approach and are just as amazing. Links below.
