# UIFont.Weight

Constants that represent standard typeface styles.

## Declaration

```swift
struct Weight
```

## Overview

Overview Use system-defined constants as interchangeable values for weight. Each constant corresponds to a different value that indicates the weight of a font. Use these constants to specify the weight parameter in systemFont(ofSize:weight:). When providing a weight that doesn’t precisely match a font face in the family, the system locates a face that most closely matches the request. note: Font familyNames don’t include all system-defined font constants.
