Week 249

Happy Thursday! How are you?

I’ve seen so many good articles this week that it’s been particularly hard to write this issue (sorry for the delay 😅). Apple rolled out public link invite to TestFlight, and we got a long and insightful article on the official Swift blog about How Mirror Works by @mikeash. Moreover, the Swift 5.0 Release Process was announced, focusing on ABI stability.

We also got @timacfr’s yearly analisys on the presence of Swift in Apple’s iOS apps and the trends are positive.

As much as I would like, I just couldn’t fit every interesting article in the newsletter. If you want to read all the suggested ones, you can do it, as always, on our GitHub.
