Schedule
Do iOS 2026 Workshop Day
Full-day hands-on iOS development workshops, including Intro to Foundation Models with Daniel Steinberg, Building production-ready AI with Apple Foundation Models, Gemini and Firebase with Peter Friese, and Building a Server-Side Swift App with Feather Framework, Hummingbird, and OpenAPI with Tibor Bödecs.
Intro to Foundation Models
Learn on-device Foundation Models with sessions, prompts, instructions, and tools — then this year’s additions including private cloud compute, images, and evaluations.
Building production-ready AI with Apple Foundation Models, Gemini and Firebase
Learn how to build a meal planning app and calorie tracker using Apple’s Foundation Models, Gemini, and Firebase AI Logic.
Building a Server-Side Swift App with Feather, Hummingbird, and OpenAPI
Build a type-safe Swift backend with Feather Framework and Hummingbird, using OpenAPI as the shared contract between server, admin, and client APIs.
Do iOS 2026 Conference Day 1
Conference talks, lunch, and walking dinner, including talks from Peter Friese, Dharam Kapila, Raluca Bujor, Emanuele Agosta, Matvei Novoselov, Antoine van der Lee, and Alex Antonov.
Making your iOS SaMD ready for FDA Testing
Preparing an iOS medical app for FDA approval — code, documentation, security features, and generating SBOMs without Package.swift.
Building Scalable Apps using SwiftUI
Architect a design system with reusable, accessible, and testable components to scale SwiftUI apps without losing velocity or consistency.
Lessons from Extending Obsidian for iOS
Advanced App Intents — filesystem access, JSContext bridging, rich return types, and runtime execution modes from Obsidian’s iOS app.
Building Hybrid, Agentic Apps with Apple’s Foundation Models Framework
A blueprint for intelligent, agentic features with Apple’s Foundation Models — on-device and with cloud models like PCC, Claude, and Gemini.
visionOS in Production: Real Business Use Cases
Where spatial computing already creates practical value in retail, real estate, healthcare, training, and industry — and how to tell product-fit from novelty.
Designing for All Screen Sizes
Design for the axis, not the device: a universal approach to adaptive apps from a compact 6-inch screen to a multi-display fold and a 3D window.
Do iOS 2026 Conference Day 2
More conference talks and community networking, including a live iOS security demo from Cyril Cermak, a Rust talk from Douglas Hill, an Object-Oriented UX talk from Caitlin Steele, a SwiftUI internals talk from Mihaela Mihaljevic, a talk on staying confident through change from Ekaterina Volkova, and a closing talk from Jeroen Leenarts.
Rust for iOS Developers: More Swifty than Swift
An introduction to Rust for iOS developers — tooling, typing, enums, safety, and memory management through a Swift-shaped lens.
When Your Expertise Stops Feeling Relevant
How to adapt, stay confident, and remain resilient when constant technological change makes your expertise feel outdated.
Behind The Walls: Penetrating A Secure System
A live demo attempting to break into a “secure” iOS app on a jailbroken device — runtime checks, secure communication, and what those failures mean for app design.
How to Train Your Designer
When design handoffs feel like dragon raids: Object-Oriented UX as a way to interrogate specs, structure AI output, and close the gap between what design means and what you ship.
SwiftUI Is One Graph
SwiftUI is a demand-driven graph, not a diffed view tree — measured against the shipping framework and Apple’s patents, then rebuilt in pure Swift.
Do iOS 2026 Workshop Day
Full-day hands-on iOS development workshops, including Intro to Foundation Models with Daniel Steinberg, Building production-ready AI with Apple Foundation Models, Gemini and Firebase with Peter Friese, and Building a Server-Side Swift App with Feather Framework, Hummingbird, and OpenAPI with Tibor Bödecs.
