SwiftUI ⟩ Controls ⟩ Text ⟩

⭐️ 重點

Text uses only a subset of the attributes defined in AttributeScopes.FoundationAttributes.

• Text renders all InlinePresentationIntent attributes except for lineBreak and softBreak.

• It also renders the link attribute as a clickable link.

• Textignores any other Foundation-defined attributes in an attributed string.
