Before you read the title of this link and reach for your pitchfork, remember that our legal systems are complicated and imperfect but we all still have to operate within them.
I'm certainly no fan of software patents, but I'm also not a lawyer and this is not my area of expertise. There's reassuring posts in the thread by Chris Lattner (who, it should be remembered, no longer works at Apple and so can not speak for them) and Ted Kremenek (who does). Even so, there are still concerns in the thread around how this might affect these features in other languages, or other implementations of Swift.
I was a huge fan of the Swift Weekly Brief before it unfortunately went on hiatus at the end of 2017. What I didn't realise was that it only took a very short break before it was back up and running! I somehow managed to get removed from the mailing list during the transition and so I had no idea it had been back for almost a year! I've always been a big fan of this project as it provides in-depth coverage of Swift evolution, so it fits really well alongside iOS Dev Weekly because my interests sit much more with iOS development rather than language development.
So, just in case you had also missed that the hiatus was very brief, it's now being run by Bas Broek who continues to do a fantastic job covering the Swift open source projects. If you're not already subscribed, go sign up.
