Sketchnote titled "PencilKit" discussing its features and tools for drawing on devices. It highlights challenges in drawing—like erasing, pressure sensitivity, and performance—alongside benefits of PencilKit.

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.

Yeah this could be great. It’s not something we tried so far though.

On iOS 26, I don’t understand how having every toolbar button jiggle when navigating between screens helps “bring focus to the underlying content”.

Excited about this new book. The sequel to my favourite book of last year.

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.

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.

Hi Douglas, You purchased Norway and we're super excited to hear what you think! Sharing your experience means a lot to us and will help others choose the right products for them.

From Claude Code’s constructive criticism of my blog post draft:

Line 142: The joke about AI agents feels out of place in a technical article and may date poorly."

Nice user review. Good to hear our app is doing some good in the world.

10/10 app, it stopped me from throwing my iPad across the room."
