Is your team carrying any of these warnings?

This program is designed to fix them, one by one.

  • The Swift 6 migration has been “next sprint” for months.
  • Turn on strict concurrency and hundreds of warnings appear. Nobody knows where to start.
  • DispatchQueue and callbacks everywhere.
  • You’re worried about the race conditions already in production.

Is it right for your team?

If it isn’t a fit, we’ll say so in the assessment and suggest something else.

Yes, if…

  • Teams with apps on Swift 5 or in compatibility mode
  • Tech leads who need a migration plan they can defend
  • Projects with a lot of legacy asynchronous code

No, if…

  • New projects that start on Swift 6.4 (see modern architecture instead)
  • Teams without an async/await foundation (we level that first)

What your team will be able to do

  • Plan the migration module by module, in an order you can defend
  • Understand isolation, actors, Sendable and @MainActor by default
  • Replace callbacks and queues with async/await and structured concurrency
  • Fix compiler warnings properly instead of silencing them
  • Find and fix real race conditions
  • Protect the migration with tests

Curriculum

Base curriculum: we adjust it to your code and your team’s level after the assessment.

Swift 6migrationandstrictconcurrency

Session 1Project assessment

Which modules to migrate first, and why.

Session 2Swift’s concurrency model

Tasks, isolation, actors and Sendable.

Session 3From callbacks to async/await

Conversion patterns and bridges to legacy code.

Session 4Strict concurrency in practice

@MainActor by default, nonisolated, @concurrent and the most common warnings.

Session 5Tests and verification

Swift Testing to make sure nothing breaks.

Session 6Guided migration

A real module from your project, live.

How we do it

We start with an assessment and tailor each session to what your team is building.

  1. assessment

    We get to know your team

    A conversation with whoever leads the team and, if needed, a review of your code and your processes.

  2. proposal

    We propose a plan

    Curriculum, schedule, format and budget, in writing. And, if you need it, who can handle FUNDAE for you.

  3. training

    We train on real work

    Live classes with examples from your domain, exercises and access to recordings.

  4. certification

    We certify

    We assess what was learned on a real case, and each person receives a certificate of achievement.

  5. follow-up

    We measure and stay with you

    A progress report, a review session with the team and support for questions afterwards.

What your team gets

  1. Course materials and all sample code, for your team’s internal use
  2. A recording of every session (remote or hybrid format)
  3. A group progress report with recommended next steps

Questions you ask us

The questions we hear most, already answered. If yours isn’t here, we’ll answer it in the conversation.

Is it eligible for FUNDAE funding?

Yes, we’re an accredited provider. Your company handles the application, with its own team or its usual advisers. If you have no one to do it, we’ll put you in touch with the partner we work with, who takes care of everything. (FUNDAE is Spain’s training credit system.)

Can we work on our own code?

Yes, under an NDA. The examples come from your own domain, so what the team learns shows up in their work the next day.
