🚨V5 is now released!🚨
Atributika
is a Swift library that provides a simple way to build NSAttributedString from HTML-like text, by identifying and styling tags, links, phone numbers, hashtags etc.
A standalone AtributikaViews
library offers UILabel/UITextView drop-in replacements capable of displaying highlightable and clickable links, with rich customization, and proper accessibility support.

While NSAttributedString is undoubtedly powerful, it's also a low-level API that needs a considerable amount of setup work. If your string is a template and the actual content is only known at runtime, this becomes complicated. When dealing with localizations, constructing NSAttributedString isn't straightforward either.
But wait, Atributika
comes to your rescue!
let b = Attrs().font(.boldSystemFont(ofSize: 20)).foregroundColor(.red)
label.attributedText = "Hello <b>World</b>!!!".style(tags: ["b": b]).attributedString
Indeed, that's much simpler. Atributika
is easy-to-use, declarative, flexible, and handles the rough edges for you.
Atributika
- NSAttributedString builder.
- Detects and styles HTML-like tags using a custom high-speed parser.
- Detects and styles hashtags and mentions (i.e., #something and @someone).
- Identifies and styles links and phone numbers.
- Detects and styles regexes and NSDataDetector patterns.
- Styles the entire string or just specified ranges.
- Allows all the above to be chained together to parse complex strings!
- Provides a clean and expressive API to construct styles.
- Offers a separate set of detection utilities for standalone use.
- Compatible with iOS, tvOS, watchOS, and macOS.
AtributikaViews
- Custom views with highlightable and clickable links.
- Custom text styles for
normal/highlighted/disabled
states. - Supports custom highlighting.
V5 is a major rewrite of the project, executed in early 2023. It's not fully compatible with the previous version and requires some manual migration. The introduction of breaking changes was necessary for the project's further evolution.
Here's what's new:
NSAttributedString Building
- Completely rewritten HTML parser, which fixed a multitude of bugs and improved handling of edge cases.
- More generic and robust text transforming and attribute fine-tuning APIs.
AttributedLabel / AttributedTextView
- Moved to a standalone library, independent of Atributika.
- Offers proper accessibility support.
- Improved performance and touch handling.
- AttributedLabel is based on UILabel (lightweight, with vertically-centered text).
- AttributedTextView is based on UITextView (supports scrolling and text selection, with text aligned to the top of the frame).
New examples have been added to the Demo application, including:
- Basic web browser powered by AttributedTextView
- SwiftUI integration
- Highlightable links for Markdown documents
Detect and style tags, provide base style for the rest of string, don't forget about special html symbols

Because in Belarusian/Russian we have one letter 't' (атрыбутыка/атрибутика). So basically it is transcription, not a real word.
