SwiftUI with John Sundell training

Some of the sessions for this course can be 100% remote

Join John Sundell, creator of Swift by Sundell, for two days full of workshops and training all about SwiftUI. Learn the fundamentals of building apps using Apple’s declarative UI framework, how to architect apps using it, and essential techniques for building robust data flows and state management.

The goal of this workshop is to prepare you for either writing new apps completely using SwiftUI, or to start adopting SwiftUI within existing UIKit-based iOS code bases. If you enjoy the Swift by Sundell website, podcast and videos — you’ll love these hands-on workshops!

Every SwiftUI update and improvement that will be announced by Apple during WWDC will be included in this training.

This training is organized by Swift Paris Trainings (aka Greg Lhotellier) in partnership with Delicious Insights.

  • World-renowned expert trainer
  • Multiple hands-on projects
  • State-of-the-art tech
  • Latest best practices


The SwiftUI training course empowers trainees to:

  • Get familiar with SwiftUI’s various APIs and views.
  • Learn the fundamentals of SwiftUI-based app development, focused on iOS.
  • Understand SwiftUI’s layout and state management systems.
  • Explore various architectural patterns and ways of building robust data flows for SwiftUI-based apps.

    • How SwiftUI’s layout system works
    • Layout options available
  4. State management

    • Managing state within a SwiftUI view hierarchy
    • When to use what layout method?
  5. Bridging the gap between SwiftUI and UIKit

    • How to bring UIKit-based views into SwiftUI
    • How to bring SwiftUI-based views into UIKit
  6. View architecture

    • Architecting and structuring SwiftUI view implementations
    • When to build reusable components
    • How to compose views
  7. Data flows

    • Building increasingly sophisticated data flows between views
    • Optimizing for maintainability

Intended audience and pre-requisites

The training takes place entirely in English, so a sufficient spoken understanding of English is mandatory.

Trainees must also have reasonable experience in developing apps with Swift and developing iOS apps with UIKit, and basic proficiency with Git and command-line tools. We emphasize that this training is not intended for complete beginners, but targeted at people with prior professional experience of app development with Swift and on iOS (not necessarily in the same setting).

Trainees must bring a Macbook capable of running Apple's developer tools with reasonable performance, and have the latest non-beta Xcode installed.

Unless otherwise specified, predefined-dates, multi-client sessions are held in French, so attendees should be reasonably fluent. You are naturally welcome to book custom dates for your company using the link above.


When the training starts, trainees receive all the related slides and supporting material in a web-based format, so they can easily follow along.

Once the training is done, they also get an extremely content-rich debrief e-mail, a reference archive with all finalized codebases (fully annotated and tested), all related slides and various complementary resources.


  • Sessions run 7hr a day, or 4hr12 a half-day, adding up to 14hr, 21hr or 28hr.
  • Full days run from 9:30 to 12:30 and 14:00 to 18:00, half-days run from 13:48 to 18:00.
  • (For or U.S. friends, that's 9:30a-12:30p / 2p-6p and 1:38p-6p Paris time, respectively.)
  • For custom dates booked specifically by your company, the schedule can be adjusted to better suit your needs. In particular, we can use half-days locked on reasonable hours in your timezone, e.g. 9a-12:30p EST or 8a-11:30a PST.
  • Every trainee uses their own laptop or workstation.
  • The laptop brought by the trainee must be a Macbook capable of running Apple's developer tools with reasonable performance, and have the latest non-beta Xcode installed.

  • Training sessions range from 5 to 10 trainees.
