New "Swift Evolution Monthly" newsletter / article series

Today, I published the first issue of a new article series where I'm trying to give a summary of interesting things that have happened here in the Swift Forums, mostly about recently accepted or currently reviewed proposals. In the first issue, I also decided to give some background on Swift Evolutions history. In future issues, I'm planning to mention some interesting pitches that haven't made it to an official review yet, too.

If you're interested in such a summary post, feel free to check it out:

I'm open to any kind of feedback, including of course corrections to my understanding of the proposals mentioned there. I don't claim to understand them all fully with my app developer perspective, so just ping me if you find any mistakes or misunderstandings, so I can correct them.

UPDATE: I just set up a newsletter for this article series as it seems some prefer that format:


Is there an RSS/Atom feed I can subscribe to?

I just published the 2nd issue of my monthly evolution summary:

Please tell me if you find I say anything wrong. I'm especially not sure about my explanation of Existentials in this case, I hope I got that right.


3rd issue is out now with 5 more proposal summaries & 10 recently active pitches linked:

If you have any feedback, please let me know so I can improve future issues for everybody!


Fourth issue out now, covering SE-0359 to SE-0362 & linking to 11 more recently active pitches:

Fifth issue out now, summarizing SE-0363 to SE-0366 & linking to 11 more recently active pitches:

Note that I moved the articles to my own blog website as some people don't seem to like Medium.

Feedback is welcome, as always.


September (+ August) issue out now, summarizing SE-0367 to SE-0372 & linking to 15 active pitches:

Minor issue, but:

Here are 10 more use cases for macros:

  1. Domain-specific languages (DSLs) – e.g. mathematics, database queries
  2. Code generation – e.g. JSON to Codable struct
  3. Debugging – e.g. print value of variable before & after a function call
  4. Performance optimization – replace runtime checks with compile-time checks
  5. Syntax extensions – e.g. new control flow constructs or data types
  6. Functional programming – e.g. simulate curried functions
  7. Code instrumentation – e.g. measure performance, monitor usage
  8. Algorithmic complexity analysis – e.g. determine time complexity of sorting
  9. Code obfuscation – e.g. for hard-coded Strings like API keys

This list contains 9 use cases, not 10.
