Defines a text transformation that can affect the visual appearance of a string.

## Declaration

```occ
typedef NSDictionary<NSString *,id> *(^)(NSDictionary<NSString *,id> *) UIConfigurationTextAttributesTransformer;
```

## Discussion

Discussion Use a transformer to affect how your attributed text appears on the UI. You provide a closure when initializing the transformer. Your closure accepts a container with the current text attributes and returns a container with the new text attributes. UIConfigurationTextAttributesTransformer transformer; transformer = ^(NSDictionary<NSAttributedStringKey, id> *incoming) {     NSMutableDictionary<NSAttributedStringKey, id> *outgoing = [incoming mutableCopy];     outgoing[NSForegroundColorAttributeName] = [UIColor blackColor];     outgoing[NSFontAttributeName] = [UIFont boldSystemFontOfSize:20];     return outgoing; };
