# system(_:design:weight:)

Gets a system font that uses the specified style, design, and weight.

## Declaration

```swift
static func system(_ style: Font.TextStyle, design: Font.Design? = nil, weight: Font.Weight? = nil) -> Font
```

## Discussion

Discussion Use this method to create a system font that has the specified properties. The following example creates a system font with the Font.TextStyle.body text style, a Font.Design.serif design, and a bold weight, and applies the font to a Text view using the font(_:) view modifier: Text("Hello").font(.system(.body, design: .serif, weight: .bold)) The design and weight parameters are both optional. If you omit either, the system uses a default value for that parameter. The default values are typically Font.Design.default and regular, respectively, but might vary depending on the context.
