FloatingPointFormatStyle.Attributed
A format style that converts integers into attributed strings.
Declaration
struct AttributedOverview
Use the attributed modifier on a FloatingPointFormatStyle to create a format style of this type.
The attributed strings that this format style creates contain attributes from the AttributeScopes.FoundationAttributes.NumberFormatAttributes attribute scope. Use these attributes to determine which runs of the attributed string represent different parts of the formatted value.
The following example finds runs of the attributed string that represent different parts of a formatted currency, and adds additional attributes like foregroundColor and inlinePresentationIntent.
func attributedPrice(price: Decimal) -> AttributedString {
var attributedPrice = price.formatted(
.currency(code: "USD")
.attributed)
for run in attributedPrice.runs {
if run.attributes.numberSymbol == .currency ||
run.attributes.numberSymbol == .decimalSeparator {
attributedPrice[run.range].foregroundColor = .red
}
if run.attributes.numberPart == .integer ||
run.attributes.numberPart == .fraction {
attributedPrice[run.range].inlinePresentationIntent = [.stronglyEmphasized]
}
}
return attributedPrice
}User interface frameworks like SwiftUI can use these attributes when presenting the attributed string, as seen here:
