Best resources for Advanced iOS Developer (Swift)

In my humble opinion, of course (updated 10.10.2019)

Thanks to undraw.co for a great illustration

For a long time, I’ve had a folder in my browser with the collection of articles and videos about iOS development + Swift which were good for me to read and reread. I’m pretty sure most of the developers have their own libraries with the best stuff.

So I decided to share mine in the glory of the Information 🤓
