# weight(of:)

Returns an approximation of the specified font’s weight.

## Declaration

```swift
func weight(of fontObj: NSFont) -> Int
```

## Parameters

- `fontObj`: The font whose approximate weight is returned.

## Return Value

Return Value An approximation of the weight of the given font, where 0 indicates the lightest possible weight, 5 indicates a normal or book weight, and 9 or more indicates a bold or heavier weight. Because this method returns only an approximation of a font’s weight, it is not guaranteed to return the exact weight with which fontObj was initialized.
