# bold(_:) Adds or removes bold or emphasized styling on the font. ``` func bold(_ isActive: Bool) -> Font ``` ## Discussion For fonts created from text styles, passing `true` could mean applying emphasized styling, which does not necessarily mean the bold weight specifically, so this modifier is not to be confused with . For example: ``` Font.body.bold(true) ``` will most likely get you the emphasized version of body text style, which is often in weight. While ``` Font.body.weight(.bold) ``` will specifically get you the body text style font in the weight. Using: ``` Font.body.bold(false) ``` will remove any emphasized styling from the font returning to its default weight which is most likely but not guaranteed to be 0.0 or [`regular`](/documentation/SwiftUI/Font/Weight/regular). --- Copyright © 2026 Apple Inc.
