Father, Swift dev. I like pushing all buttons, breaking things to see how it works and rebuilding. I wish news would focus more on science, and positive entrepreneurial spirits. So I will try to post about that!

I was experimenting with claude sub agents and created this tool. Might help somebody. Agents make managing conversation a lot easier. I'm still searching for the best way to use them but this is a start. I'm curious how you use it? All in #swiftlang

Just discovered Universal Control by accident. My MacBook's trackpad suddenly controlled my Mac Studio - no cables. Turns out Apple built this years ago. One keyboard, two Macs, cursor flows between screens. Works perfectly once you get it.

The AI bubble: everyone building "better search" because that's the frame people understand.
The actual shift: AI as context engineering—understanding YOUR data, YOUR work, creating value from what you already have.
That's not search. That's different.

Just double checked temporal, looks interesting. „Pure“ workflows and activities like effect operations, they even have a SideEffect term in their docs. 🙃
Replaying workflows and blocking them indefinitely also looks nice, and it’s language agnostic. 🤔

Swift gets durable workflows! The Swift Temporal SDK brings true fault-tolerant execution to server-side Swift. Write workflows that survive crashes, restarts, and failures—your code persists state automatically and resumes from interruption.

The Swift compiler is your first line of defense for server deployments. Pull runtime failures into compile-time by avoiding Any types, untyped dictionaries, and implicit unwraps. Type safety isn’t academic—it’s what keeps your servers running. #swiftlang #serversideSwift2025

From @slashmo's FOSDEM 2025 talk on server-side Swift observability:
When a request hits your edge proxy, it creates a root span. How does that trace context flow through your microservices?

Today was day 1/2 #serversideSwift2025 I loved it. I took audio using whisper note and fed transcriptions into claude. Then I installed historian mcp to analyse my conversations. This I feed to claude code to build me a swift agent. If it works I will open source if there is interest? #swiftlang
