# LibraryItem.Category

The kinds of library items that you can create.

```
struct Category
```

## Overview

When you specify a category for a library item, Xcode can group it
with similar items in the library, making it easier for you to find.
Categories provide visual treatment in the Xcode Library, but the
treatment for each category depends on where the asset resides within
the library.
