I end all of my newsletter intros with "hit reply - I read every email". And I actually mean it! This week, Stephan emailed me, looking for the print detail of Jace's physical copy of The Swift Programming Language book I mentioned in issue 94 (peterfriese.dev/newsletter/...).

peterfriese.devNot only Swift - Issue #94Someone printed a physical copy of the Swift Programming Language book, and it looks fantastic! Plus: Explore the rise of agentic coding with Pi and OpenClaw, and dive into Swift-based vector databases for on-device RAG.

This conversation led to two great things 👇 1) Stephan shared a glimpse of a 300 page book on Swift generative art he's printing for his vacation (mind-blowing work).

2) I freshly generated a new PDF for Swift 6.4 (and fixed some issues with the rendering along the way)

Tiny feedback: the rendering seems to be indenting where none is needed. See page 8 at the end of section 2. The last paragraph on page 7 overflows to page 8 where it is mysteriously indented.

Do you mean the wide margin? That's actually on purpose - the book uses Tufte-style wide margins. See page 10 for an example how this is used.
