# transformingAttributes(_:_:_:_:_:_:) Returns an attributed string created by calling a closure that transforms five attributes of a source attributed string. ``` @preconcurrency func transformingAttributes(_ k: K1.Type, _ k2: K2.Type, _ k3: K3.Type, _ k4: K4.Type, _ k5: K5.Type, _ c: (inout AttributedString.SingleAttributeTransformer, inout AttributedString.SingleAttributeTransformer, inout AttributedString.SingleAttributeTransformer, inout AttributedString.SingleAttributeTransformer, inout AttributedString.SingleAttributeTransformer) -> Void) -> AttributedString where K1 : AttributedStringKey, K2 : AttributedStringKey, K3 : AttributedStringKey, K4 : AttributedStringKey, K5 : AttributedStringKey, K1.Value : Sendable, K2.Value : Sendable, K3.Value : Sendable, K4.Value : Sendable, K5.Value : Sendable ``` ## Parameters `k` The [`AttributedStringKey`](/documentation/Foundation/AttributedStringKey) that identifies an attribute to transform. `k2` The [`AttributedStringKey`](/documentation/Foundation/AttributedStringKey) that identifies a second attribute to transform. `k3` The [`AttributedStringKey`](/documentation/Foundation/AttributedStringKey) that identifies a third attribute to transform. `k4` The [`AttributedStringKey`](/documentation/Foundation/AttributedStringKey) that identifies a fourth attribute to transform. `k5` The [`AttributedStringKey`](/documentation/Foundation/AttributedStringKey) that identifies a fifth attribute to transform. `c` A closure that receives four [`AttributedString.SingleAttributeTransformer`](/documentation/Foundation/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. --- Copyright © 2026 Apple Inc.
