If you are looking for the best way to master Swift development, you should definitely follow me and these free resources that I do. 😉

The list is strictly based on my personal opinion, I believe that these sites provide first class content for Swift developers and made a huge impact on the community. If you miss something that's because I don't want a list of hundreds of dead / useless / outdated / "put something here" links, but only recently updated (active) quality resources made by professional geeks. 🤓😂 Thanks for understanding this. 👍

Organizations, communities

Personal blogs

Newsletters (weekly)

It's really good to see that there are still plenty of dedicated people who are keeping up writing about the good and bad parts of iOS / Swift development. As you can see I prefer quality over quantity, if you subscribe to these resources you can't go wrong. 😉
