Now comes the magic of KMP: edit the shared function once and both apps change together. No copy-paste, no drift.

Open greet in commonMain and change the wording. This is the only place you touch, even though two apps depend on it.

Run the Android app again. Because it links the shared module, it instantly shows the new Welcome text with zero extra edits.

Rebuild the iOS app and the same new line appears. The shared framework was recompiled from the one source you changed.

Change behavior too, like trimming spaces. Both platforms gain the fix at once, because the logic truly lives in one place.

If greet had a bug, you fix it once and both apps are healed. That is the consistency KMP is built to give you.

Each platform compiles the shared code into its own artifact. So after an edit, both apps need a fresh build to pick it up.

Write one test for greet in commonTest and it protects every platform. A single safety net covers all your apps.

Sharing logic shrinks your surface area. Fewer lines, fewer places for bugs, and behavior that can never disagree across apps.

The text changed everywhere, but each app still styles it with its own UI. You share the brain and keep platform-native looks. 💡

You wrote shared code, called it from both apps, and proved a single edit updates them together. That is the whole KMP loop. 🎉

What happens after you edit shared logic?

One edit in commonMain flowed to both apps after a rebuild. Share the logic, test it once, and keep each UI native. 🎉
