Returns an attributed string by calling a closure that transforms three attributes, which key paths identify, of a source attributed string.
@preconcurrency func transformingAttributes<K1, K2, K3>(_ k: KeyPath<AttributeDynamicLookup, K1>, _ k2: KeyPath<AttributeDynamicLookup, K2>, _ k3: KeyPath<AttributeDynamicLookup, K3>, _ c: (inout AttributedString.SingleAttributeTransformer<K1>, inout AttributedString.SingleAttributeTransformer<K2>, inout AttributedString.SingleAttributeTransformer<K3>) -> Void) -> AttributedString where K1 : AttributedStringKey, K2 : AttributedStringKey, K3 : AttributedStringKey, K1.Value : Sendable, K2.Value : Sendable, K3.Value : Sendable

Parameters

k

The key path to an AttributedStringKey that identifies an attribute to transform.

k2

The key path to an AttributedStringKey that identifies a second attribute to transform.

k3

The key path to an AttributedStringKey that identifies a third attribute to transform.

c

A closure that receives three AttributedString.SingleAttributeTransformer instances that you use to access and alter the attributes’ ranges and values.

Return Value

An attributed string with the applied transformations to the specified attributes.
