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 sufficient experience in developing iOS apps with Swift and SwiftUI or UIKit, and basic proficiency with Git and command-line tools. We emphasize that this training is not intended for beginners, but targeted at people with prior professional experience of app development with Swift on iOS. It is also not the best fit for people with lots of experience writing RxSwift or ReactiveCocoa code, as a significant share of the training will cover similar reactive programming concepts.
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.
John Sundell is the creator of Swift by Sundell. During the past three years, he’s helped over a million developers level up their skills through over 300 freely available articles and podcast episodes, and by speaking at top tech conferences around the world.
With over a decade of professional software development experience, working for companies like Volvo and Spotify — he’s now working with several teams of various sizes, to help them improve their skills, their code, and the products that they ship.
His goal is always to help the Swift and iOS developer communities as much as he can, to share his experiences working on all sorts of apps and software products, and to help others get more out of their work as software developers.
