AI generation adapts to anything you ask. A bash script adapts to nothing. After a few months of scaffolding KMP feature modules both ways, I know which one I trust.

A driver changes the engine map from the wheel, mid-race, no pit stop required. Feature flags do the same for your app: change behaviour without shipping a build. Here's how I structure flags and remote config once, in commonMain, for both platforms.

expect/actual is easy until you leave the trivial expect fun behind. Here's what bites with expect classes, constructors, actual typealiases, and the compiler rules nobody warns you about.

An uncaught coroutine exception crashes your KMP app on both platforms, and the platform safety nets don't extend to iOS. Here's how I build crash boundaries in commonMain.

Tyre warmers keep rubber at temperature so the car has grip the instant it leaves the box. Coil 3's memory and disk cache do the same for images — and the same code now runs on Android and iOS from commonMain.

expect/actual isn't just for business logic. Here's how to build a shared barcode scanner Composable that reads through any platform's lens.

Before a race car can compete, it needs to be homologated. Before your KMP library can be used by anyone, it needs Maven Central.

The pit crew doesn't wait to be asked. They intercept the car, do their work, and the driver rejoins the race. Ktor plugins work the same way: auth, logging, and retry all happen before your business logic sees a thing.

In endurance racing every car carries a timing transponder: the circuit knows exactly where you are, every lap, every sector. This is how to put one on your KMP project.

The pit crew was always there. I just had to build it: a Gradle plugin that automates iOS and Android splash screen setup from a single config block.

Metro drops the clutch on runtime DI errors. Three patterns in a real KMP app: binding contributions, platform graphs, and child scopes.

Objective-C headers turned your Kotlin enums into class wrappers and your function signatures into noise. Swift Export sends the same data over a cleaner channel.

Why organising your garage by components is slowing down your pit stops.

A pit wall crew knows exactly what to do without being told from scratch. Custom Gemini commands work the same way.

Before the car hits the grid, telemetry confirms every sector. Before your UI ships, runComposeUiTest confirms every composable.

Navigation 3 supports shared element transitions. It always did. LocalNavAnimatedContentScope was the piece the docs never mentioned.

The intermediary between your app and the database never disappeared. It just stopped being your problem.

Track limits don't stop you from going wide. They penalise you for it. Custom Detekt rules work the same way.

StateFlow is your lap timer — always showing the latest lap. SharedFlow is the race radio — you only hear what's broadcasted while you're tuned in.

Same engine, different cockpit: how Compose and SwiftUI handle side effects when sharing a Kotlin Multiplatform ViewModel.
