Both in November in superb, well-connected cities (direct trains from London).12 Oct 2026 18:12 +0000at://did:plc:yd22bcpy36vw6ez7phpueyt5/app.bsky.feed.post/3mxp4ozal6g2xhttps://bsky.app/profile/douglashill.co/post/3mxp3smxvaw2jHope everyone at SwiftLeeds and KotlinLeeds this week learns a lot and has a wonderful time.

The scale of the conference was impressive. It felt very different from the iOS conferences I’ve been to. Here are my notes on the event.12 Oct 2026 07:52 +0000at://did:plc:yd22bcpy36vw6ez7phpueyt5/app.bsky.feed.post/3mxo22os5as2ohttps://bsky.app/profile/douglashill.co/post/3mwnin3bvw527Exciting morning for PDF Viewer with Firebase29 Sep 2026 09:16 +0000at://did:plc:yd22bcpy36vw6ez7phpueyt5/app.bsky.feed.post/3mwnin3bvw527https://bsky.app/profile/douglashill.co/post/3mwnaxs5s2h27Next week, I’ll be hosting a Rust for Mobile Developers round table discussion at next.app devCon.

Workaround: Add a “Get text from (rich text)” and count with that instead.

We exchange messages with people’s robots, or more likely we have our robots talk to their robots. Efficient, but makes me think it would be nice to hang out with people.03 Jul 2026 10:37 +0000at://did:plc:yd22bcpy36vw6ez7phpueyt5/app.bsky.feed.post/3mpqfhhasp72xhttps://bsky.app/profile/douglashill.co/post/3mpjyvwnn3h2pNotes from attending the RustWeek conference in Utrecht.30 Jun 2026 22:00 +0000at://did:plc:yd22bcpy36vw6ez7phpueyt5/app.bsky.feed.post/3mpjyvwnn3h2phttps://bsky.app/profile/douglashill.co/post/3mozgetv5752aLooking forward to being back in Wales in September to talk about Rust at iOSDevUK. Early bird conference tickets are available until the end of this month. It’s my favourite and best-value iOS conference. Also let me know if you’re interested in hiking in Eryri/Snowdonia the weekend before.24 Jun 2026 07:45 +0000at://did:plc:yd22bcpy36vw6ez7phpueyt5/app.bsky.feed.post/3mozgetv5752ahttps://bsky.app/profile/douglashill.co/post/3mm7phttula2rWWDC labs are conspicuously missing from the activities this year.

Sounds like a way to build an end-to-end encrypted replacement for iCloud/CalDAV contacts sync if you can get your head around the difference between ContactItemEnumerating and ContactItemEnumerator.14 Apr 2026 07:18 +0000at://did:plc:yd22bcpy36vw6ez7phpueyt5/app.bsky.feed.post/3mjgtqj26un2nhttps://bsky.app/profile/douglashill.co/post/3milewqruoj2sInteresting evening yesterday at Rust London learning all sorts. Dan Groshev spoke about picking a dominant colour from an image. (I used a similar approach in Jamie Oliver‘s Recipes in 2014.)
