iOS developer trainee · open to alternance

I build native iOS apps in Swift, then ship them everywhere.

I am Fabian Gelin, training as an iOS developer at Simplon.Co in Montreuil. I work in SwiftUI and reach for Skip to take a single Swift codebase straight to Android - no rewrite, no middle layer, no intermediation between the code and each platform.

Now

Training as an iOS developer at Simplon.Co Montreuil - daily Swift and SwiftUI practice on real project briefs.

Now

Exploring Skip.tools to compile SwiftUI codebases to native Android, keeping a single source of truth.

Starting an iOS developer alternance - the work-study apprenticeship I am lining up now.

// skillsThe tools I reach for, and why.

Swift

My core language. Strong typing, value semantics, and concurrency with async/await for code that stays readable as it grows.

SwiftUI

Declarative interfaces built from composable views. State-driven layouts, animations, and a fast preview loop.

Skip.tools

Transpiles a SwiftUI app into a native Android app from one codebase - real Kotlin, no embedded runtime.

SwiftUI to AndroidnativeKotlin

Zero-intermediation architecture

Cross-platform without a heavy abstraction in the middle. Each platform gets native code, so there is nothing translating at runtime.

// approachHow I think about shipping software.

Native first

Start in SwiftUI and respect the platform - the gestures, the haptics, the system feel people already trust.

One codebase

Use Skip to carry that same SwiftUI code to Android, so a feature is written once and lands twice.

Nothing in between

Avoid runtime bridges and wrappers. Less intermediation means fewer surprises and faster, leaner apps.

Looking for an iOS alternance from January 2027.

If your team takes on an apprentice and works on iOS, send a note. It lands straight in my inbox and I read every one.
