# Platform specific

In some scenarios when you need to execute platform-specific logic directly from common code, you can use a `when` expression to determine the platform at runtime:

```
when (platform()) {
    AppPlatform.IOS -> TODO()
    AppPlatform.ANDROID -> TODO()
    AppPlatform.DESKTOP -> TODO()
}
```
