Swift Rockies 2026

​

I am really excited to announce that I will be speaking at Swift Rockies this summer in Calgary, Alberta, Canada.

Swift Rockies is a practitioner-focused, community-driven Swift & iOS conference that brings together experienced iOS engineers and mobile developers for two days of deep technical talks, real-world war stories, and meaningful connections, plus an optional pre-conference day of hands-on workshops

With around 150–180 attendees, Swift Rockies maintains an intimate, retreat-style, single-track atmosphere that prioritizes learning, hallway conversations, and community over sales pitches. The content is tailored primarily for intermediate to senior iOS developers, while still including a few sessions that are accessible to those earlier in their Swift journey.

Set against the stunning backdrop of the Canadian Rockies, this isn’t just another tech conference. It’s a gathering of passionate developers who share a love for Swift, iOS development, and the vibrant community around it. Expect opinionated talks, hard-earned lessons from the field, and plenty of time to connect with fellow builders.

Tickets are not yet available, but if you are interested in attending, visit the web site and sign up for the waitlist.

Recent Videos

Since my last newsletter, I released two more videos.

Initializing Observable Classes If you’ve ever wondered where to create your observable class in SwiftUI, this video walks through every case with real examples. Inspired by and credited to @natpanferova’s blog. Seven demo views that finally make it click. ​

Mastering Switch Statements If you think switch is just cleaner if-else, you’re missing the best part. Learn how Swift’s switch handles ranges, tuples, enums, and UI state in this deep dive. ​

Upcoming Videos

For my next two videos, I am going to focus on SwiftUI Pickers.
SwiftUI pickers seem straightforward until selections stop updating and the UI lies to you. Next week’s video breaks down the real rules behind pickers, including when tags are required, how enums and optionals behave, and which picker styles belong in real apps. A must-watch if pickers have ever confused you.

Date and Color Pickers.

On the following Sunday, I provide you with a hands-on guide to other SwiftUI pickers. You’ll learn DatePicker components, ranges, and styles, a clean pattern for optional dates, how MultiDatePicker selections work (and how to display them), and when to switch to UIKit for a better color picker experience.

Stanford CS193p - Developing Apps for iOS

Like many of you, I have watched my fair share of courses about Swift and SwiftUI app development over the years. The standard one that I always recommend to people is Paul Hudson’s 100 Days of SwiftUI. This is a great introduction to SwiftUI and you can really get your feet wet and learn a lot in a short amount of time.

If, you are looking for something a bit more structured and in-depth, I highly recommend the free Standford CS193p course.
​
Stanford University’s legendary CS193p course, Developing Apps for iOS using SwiftUI, is now fully accessible online with all lectures and materials linked directly on the course site. It’s the same curriculum Stanford students take to learn modern iOS development with Apple’s SwiftUI framework.

The course walks through building real applications from scratch using Xcode and SwiftUI. Lectures progress from fundamentals like Views and layout to deeper topics such as data flow, animations, navigation, persistence with SwiftData, and app architecture. Each lecture links to corresponding videos and assignments, letting independent learners follow the whole sequence.
​
This Spring 2025 version pre-dates iOS 26 and Xcode 26 releases, but the content remains largely compatible and highly relevant for anyone serious about mastering iOS app development.

CS193p consistently ranks as one of the most respected free resources for SwiftUI developers worldwide. It’s structured, deep, and practical, making it ideal for learners who want more than brief tutorials.

My Year with ChatGPT

If you use ChatGPT, you might want to check out your own Year End Report. Just ask it for the report and it will walk you through it.

I use ChatGPT quite a bit, mostly for generating mock data, creating sample code, and repurposing my video transcripts into YouTube descriptions, titles, tags, and social media posts. It is a fun and surprisingly insightful exercise.

I learned that I sent 5,069 messages this year, which put me in the top 5 percent of users, and that I engaged in 762 different chats. I also used ChatGPT to plan my entire trip to southern France last fall, which worked out incredibly well.

I was especially amused by the little award it gave me at the end. It almost makes that monthly subscription feel justified. Almost.

IIf you enjoy what I do and want to support my work, you can join my Ko-fi community and either make a one-time donation or become a monthly supporter for as little as $5/month. Monthly supporters get early access to my videos as soon as they’re uploaded to YouTube (as unlisted videos), sometimes up to a month before they’re made public. Monthly supporters also get priority responses to their questions, and I’m happy to help with coding challenges.

In addition to PayPal, Ko-fi now supports Stripe, which makes it easier to pay by credit card.
