Last December I wrote that planning for Do iOS 2026 had started. The venue was still a negotiation, the Call for Papers was not open, and I sketched the themes I expected the year to demand. Most of that is now a program. The details, bios, and ticket shop are on do-ios.com.
We are back at the NEMO Science Museum in Amsterdam, November 10–12, 2026.
The shape matches 2025. Talks at NEMO, lunch on both conference days, and a walking dinner on Wednesday evening. Daniel Steinberg and I will host again.
NEMO is at Oosterdok 2, a short walk from Amsterdam Central Station.
The CFP closed on August 16. I asked for work logs from people shipping software, and that is what came back. The themes shifted from the list I wrote in December.
Foundation Models and on-device Apple Intelligence came back harder than anything else. visionOS came back as production work. SwiftUI came back twice, from opposite directions: how you scale a design system, and what the framework actually is. Security, regulated software, App Intents, adaptive layout, and the strain of keeping up all made the program as well.
Embedded Swift and a dedicated Swift concurrency session are absent from the announced talks. The submissions concentrated on the topics above, and that is the program I want to run.
Two full-day workshops. Both are hands-on. Bring a Mac.
Daniel Steinberg — Intro to Foundation Models. Sessions, prompts, instructions, and tools, then this year's additions: Private Cloud Compute, images, dynamic profiles, and evaluations. You need Xcode 27, and a device you can deploy to on iOS 27 or macOS 27.
Peter Friese — Building production-ready AI with Apple Foundation Models, Gemini and Firebase. A meal planner and calorie tracker: on-device Foundation Models, Gemini through Firebase AI Logic, structured output, images, streaming, and App Check. You need the latest Xcode and a physical iPhone. The exercises run on a Mac.
Peter Friese — Building Hybrid, Agentic Apps with Apple’s Foundation Models Framework. @Generable, tool calling, Private Cloud Compute, Claude, Gemini, and dynamic profiles. The conference version of the workshop subject, in Swift.
Dharam Kapila — Lessons from Extending Obsidian for iOS. App Intents from the shipping app: filesystem access, JSContext bridging, rich return types, and runtime execution modes.
Raluca Bujor — Building Scalable Apps using SwiftUI. A design system of reusable, accessible, testable components, for when the app grows faster than the UI stays consistent.
Emanuele Agosta — Designing for All Screen Sizes. One foundation that changes shape from a compact phone, to a foldable, to a 3D window.
Matvei Novoselov — visionOS in Production: Real Business Use Cases. Where spatial computing already earns a place in retail, real estate, healthcare, training, and industry, and where it only adds novelty.
Alex Antonov — Making your iOS SaMD ready for FDA Testing. Preparing a medical iOS app for FDA review: the code, the documentation, the security features, and generating SBOMs for a project without Package.swift.
Cyril Cermak — Behind The Walls: Penetrating A Secure System. A live attempt to break into a “secure” iOS app on a jailbroken device, and what those failures mean for the design.
Douglas Hill — Rust for iOS Developers: More Swifty than Swift. Tooling, types, enums, and memory management, for people who already think in Swift.
Caitlin Steele — How to Train Your Designer. Object-Oriented UX as a way to interrogate a spec, give an AI something structured to work from, and close the gap between the design and the build.
Mihaela Mihaljevic — SwiftUI Is One Graph. SwiftUI as a demand-driven graph, checked against the shipping framework and Apple’s patents, then rebuilt in pure Swift.
Ekaterina Volkova — When Your Expertise Stops Feeling Relevant. How to stay steady when the stack keeps moving and your confidence does not.
Three sessions are still unpublished. Antoine van der Lee is confirmed for Wednesday; his topic follows. Thursday afternoon still has one open speaker slot. I am speaking on Thursday too, and I will publish that topic when it is ready.
RocketSim and Flitsmeister are supporting this year's conference.
We are still looking for partners. If your company builds something iOS developers actually use, write to info@do-ios.com.
Three passes:
Tickets are on sale at do-ios.com. The agenda, speaker bios, and practical details are there too.
See you in Amsterdam.
