Audelin: Them 1, Them 2
After every call, Audelin splits the far side of the transcript into separate remote speakers, numbers them Them 1, Them 2, and names each one only from their own introduction.
iOS tech lead · building with AI agents
Notes from building software with AI agents, and the Swift years before them.
I lead iOS development at a bank and build products with coding agents that work from specs and tests. This is where I write down what works, what didn't, and why.

A call-summary settings screen makes Audelin's next design question concrete: where the transcript goes, who pays, and what a fallback changes.
RexLab: The Dig Site
RexLab's games each had a look of their own. This week they became one world, a dig site from sky to bedrock, drawn first and approved by eye before any code merged.
Agonara Session: Reading a Lecture on a Phone
Agonara Session lets a student read an Agonara course on a phone, first in a Telegram bot, then as a web page on the local network. Why a lecture is paged by screen rather than by section, what Telegram messages can and cannot do, and how a Go runner redeploys itself when trunk moves.
Audelin: Reading While the Words Arrive
Speaker symbols, readable selections and a viewport that stays put make Audelin's live transcript easier to follow while the conversation continues.
Audelin: A Millisecond to Update the Transcript
Audelin's live transcript used to rebuild the whole call whenever a word changed. Making the work follow the live tail brought a late view update from hundreds of milliseconds to about one.
Mizan BLE: the Till Next Door
A phone that pays at a till must never pay the till next door. How Mizan BLE picks the nearest host by smoothed signal strength, what a real iPad and iPhone measured, why the first picker flickered at arm's length, and what iOS does not let a Bluetooth payment do.
Mizan BLE: Every Way a Transaction Ends
A payment over Bluetooth has one way to succeed and many ways to stop. How Mizan BLE splits each side into a chain of state machines, why the countdown stops once the amount is sent, and how an iPad ends a link it is not allowed to close.
