# LaunchTaskID

An identifier for a task measured as part of an extended app launch.

## Declaration

```swift
struct LaunchTaskID
```

## Discussion

Discussion LaunchTaskID is RawRepresentable and ExpressibleByStringLiteral. You can pass a string literal directly as the id argument to trackLaunchTask(id:onTrackingError:_:) or trackLaunchTask(id:onTrackingError:_:): await manager.trackLaunchTask(id: "initial-data-load") {     await loadInitialData() } Choose unique, descriptive names for each task you track. The system uses the ID to associate measurements with the specific work you perform during launch.
