Don't let this gap widen
Why this program matters
Without this advanced Swift training, your iOS apps risk concurrency bugs affecting 40% of users, memory crashes that triple negative App Store reviews, development times inflated by 30% due to lack of optimizations, Apple validation rejections due to obsolete architectures, loss of competitiveness against developers mastering async/await, and maintenance costs exploding to 50k€/year for junior teams.
Invest 35 hours to avoid these pitfalls and boost your freelance income by 25%.
Program
Module 1Swift Concurrency: async/await, actors, and structured concurrency
Dive into modern concurrency mechanisms, code asynchronous tasks with async/await using Xcode, simulate real multithreaded scenarios on mobile app cases, build actors for secure shared data management, test live to avoid data races, leave with exercises ready to integrate into your iOS projects.
Module 2Advanced Swift Features: protocols, generics, and extensions
Deepen protocols with associated types and primary associated types, generate generic code for performant collections via Xcode playgrounds, apply extensions to existing iOS frameworks, solve concrete challenges like implementing builder patterns, create reusable deliverables, boost your productivity with pro tips that transform your apps into elite code.
Module 3Performance Optimization: Instruments, memory, and profiling
Analyze and optimize your code with Xcode Instruments, track memory leaks in real apps, implement advanced ARC and weak references, measure FPS gains for smooth UIs, practice on critical cases like SwiftUI leaks, produce performance reports, master techniques that reduce crashes by 50% and accelerate your deployments.
Module 4iOS Architectures: MVVM, Combine, and Advanced SwiftUI
Build scalable apps with MVVM and Combine publishers, integrate SwiftUI for dynamic reactive views, code complex data flows in a group on Xcode, refactor an existing project live, generate testable architectures, leave with a functional production-ready prototype, adopt patterns that facilitate maintenance and evolution of your iOS apps.
Module 5Advanced Testing and Deployment: XCTest, CI/CD for App Store
Develop comprehensive test suites with XCTest and mocks, integrate automated UI tests for SwiftUI, set up Fastlane for CI/CD, simulate App Store submissions with security audits, finalize a complete project in a team, obtain certification via tested deliverable, secure your releases against 90% of common rejections.

Our method
Training quality, guaranteed at every step
Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.
You meet the trainer beforehand
30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.
- Live briefing on goals and team context.
- Veto right — we swap the trainer for free if needed.
Content tailored to your context
No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.
- Hands-on cases drawn from your stack and projects.
- Program co-written then validated by your team.
Continuous quality follow-up
Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.
- NPS, knowledge quizzes and skills self-assessment.
- Satisfaction guarantee: fully satisfied or free rework.
A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
