SwiftLeeds day 1
5 October 2025
Now I’m in Paris catching up with some Swift Connection people but confusingly not attending this conference, because I’ll take the train onwards to the UK tomorrow for SwiftLeeds. Both are quite nice conferences. »
I was lucky to be in Tirol for the ski season opening on Friday!

The schedule for Pragma conference just went up. Looks fabulous. Looking forward to it! (I’ll be taking the train down through the French Alps. The Paris-Milan route reopened this year after a landslide in 2023.) »

We’re hosting an NSLondon pub evening tomorrow in conjunction with the Server-Side Swift Conference. Sign up on Meetup or just turn up. (I’m away but back in the UK next week for SwiftLeeds.) »

Our PDF Viewer update for iOS 26 and macOS 26 is out on Apple’s app store. It’s glass time. »

Update of our PDF SDK ready for the new design on iOS 26 is out. Hard designing for Liquid Glass without having many examples of other apps yet. It was an amazing team effort getting this out during our company retreat! Read more in the Nutrient iOS SDK 26 release notes. »

Excited about this new book. The sequel to my favourite book of last year.
We’re running another NSLondon coffee and code morning tomorrow. Meet at 11 at WatchHouse Marble Arch by Hyde Park. I’ll be there. »

For some reason, Xcode 26 beta is reverting our swiftpm/Package.resolved
file from the version 3 format to version 1. I guess it‘s fine, just annoying diff noise as the whole file changes. I’m concerned it‘s going to want to go back to version 3 next week.

We released Nutrient iOS SDK 14.12 (formerly PSPDFKit). The release notes aren’t really about this release, but instead about what’s happening next month. Apple’s big UI update needs navigating carefully, as using the wrong version of Xcode will lead to trouble. »
Trying to use dictation more at work to give my wrists a break, but end up with nonsense like “Revenue cat five switches to stalk it too”. (It’s about this.) »

I wrote a detailed article reviewing the range of NotificationCenter
APIs (selector, closure, Combine, async sequence), leading up to MainActorMessage
and AsyncMessage
. Also covers some API design considerations and bridging between messages and notifications. »
We have a new blog post from Shadrach going deep with new App Intents API in iOS 26 for interactive snippets, which can used to add steps in Shortcuts that dynamically receive input from the user. »

Had to look up a thing in a project in CLAUDE.md
because it was more comprehensive than README.md
. Humans usability is now a secondary concern.

Today’s lesson: With Foundation Models, use the same beta of Xcode and iOS. Any use of tool calling using Xcode 26 beta 4 running on iOS 26 beta 5 crashes at launch with dyld: Symbol not found: _$s16FoundationModels16GeneratedContentV10propertiesACs13KeyValuePairsVySSAA013ConvertibleTocD0_pG_tcfC

For our iOS team at Nutrient, WWDC is a very special week, so I wanted to share how we make the most of this exciting occasion. We do remote WWDCs like we used to do in-person WWDCs: We set aside other work and focus on labs, learning and experimentation. »

Interesting email in my inbox. I’m thinking about purchasing Greenland next.
