JP MensThe things I learn, even at my age, simply by reading documentation are WILD!
Today: #SQLite3
"In addition to reading and writing SQLite database files, the sqlite3 program will also read and write ZIP archives."

HealthKit @ 🍎
David SmithTwo obscure Swift changes I want to note:
ASCII String literals bridged to ObjC will produce a different type in the beta OSs. This generally has no impact (other than greatly improved performance), but code incorrectly treating `NSString *` as `char *` or `SEL` may need to change (e.g. %s format strings).
A message will be logged in any situation we're applying compatibility workarounds for this, and the workaround will be disabled if you use the latest SDK version.
Thomas BartelmessThere are some fresh SQLite bits in Beta 2 of Apples OS’s.
Chris AdamsonFoundation things for which docs are still in the works: NotificationCenter is now concurrency-friendly with a new "Messages" type. Lots of notifications in Foundation, UIKit, and AppKit are now available with this approach. Also in Foundation, there's a "#bundle" macro that's way nicer than doing Bundle(MyClass.self)… or god forbid, a hard-coded bundle identifier. https://developer.apple.com/documentation/updates/foundation

Konrad 'ktoso' MalawskiThis talk may be the highlight of this year's wwdc if you're interested in profiling and high performance code on apple platforms: https://developer.apple.com/videos/play/wwdc2025/308
It shows a new cpu profiler that collects *all* events, and gives exact traces, some hints about cpu counters too.
Paul HudsonAnnual reminder: A whole bunch of new API just shipped at #WWDC25, but it's early days – if you have suggestions for improvements, or find early bugs, please report them *now*. Filing feedback early maximizes the chance of your feedback being addressed before release.
