How do I style text with Attributed in a Swift iOS app?

Use the fluent API by calling .at.attributed on a string with a closure or attributes object. For example, apply foreground color and font in a closure, as shown in the README's 'Chalkduster' example for inline styling.

Attributed or native NSAttributedString for my project?

Attributed is better for type safety and readability to avoid runtime errors, but if you're in a pure Objective-C environment or prefer minimal dependencies, native NSAttributedString might be sufficient despite more boilerplate.

How to apply different styles to specific parts of a string?

Use the range-based application feature: create an attributed string, then apply attributes to ranges using methods provided. This allows fine-grained styling, such as highlighting certain words, without complex dictionary manipulations.

Is Attributed compatible with Objective-C code?

No, Attributed is Swift-only and leverages modern Swift features like closures and type inference, so it won't integrate directly with Objective-C codebases without Swift bridging or refactoring.

What if I need an attribute not listed in Attributed's docs?

You can open an issue on GitHub to request it or submit a pull request, as the README suggests. However, this means you might face delays or need to implement custom extensions yourself for unsupported attributes.

How does Attributed handle performance with large texts?

Attributed is a lightweight wrapper around NSAttributedString, so performance is similar, but the additional abstraction layer might introduce minor overhead. For most use cases, it's negligible, but benchmark if optimizing for high-volume text rendering.

What is Attributed?

Attributed is a Swift µframework that provides a fluent, strongly typed, and safe API for creating and manipulating NSAttributedString instances. It solves the problem of NSAttributedString's error-prone dictionary-based interface by offering compile-time safety and a more intuitive syntax for styling text in iOS and macOS apps.

Target Audience

iOS and macOS developers working with styled text who want a safer and more expressive alternative to the standard NSAttributedString API, particularly those using Swift.

Value Proposition

Developers choose Attributed because it eliminates runtime crashes from incorrect attribute keys, reduces boilerplate with a fluent API, and integrates seamlessly with existing NSAttributedString workflows while being lightweight and focused.

Overview

µframework for Attributed strings.

Use Cases

Best For

Building styled text interfaces in Swift-based iOS apps
Replacing error-prone NSAttributedString dictionary usage with type-safe code
Creating complex attributed strings with multiple styles and ranges
Combining multiple attributed string segments with different attributes
Improving code readability and safety in text-heavy UIKit or AppKit projects
Migrating legacy Objective-C attributed string code to modern Swift

Not Ideal For

Projects exclusively using SwiftUI, where Text modifiers are the standard for styling.
Objective-C codebases without Swift integration, as Attributed is Swift-only.
Applications requiring text styling on platforms other than iOS or macOS.
Simple apps with minimal attributed string usage where the overhead of a new framework isn't justified.

Pros & Cons

Pros

Type-Safe Interface

Prevents runtime crashes by replacing error-prone [String: Any] dictionaries with compile-time checked attributes, as emphasized in the README for safety.

Fluent API Design

Enables method chaining for readable and concise attributed string creation, reducing boilerplate compared to standard NSAttributedString APIs.

Easy Concatenation

Provides a + operator to combine NSAttributedString instances, simplifying assembly of complex styled texts without manual range management.

Closure-Based Styling

Supports creating attributed strings through closures for inline and reusable attribute definitions, enhancing code organization and reusability.

Cons

Limited Attribute Coverage

The README acknowledges users might need to request missing features, indicating not all NSAttributedString attributes are supported out of the box, requiring extensions for niche cases.

External Dependency Overhead

Adds a framework dependency via CocoaPods or Carthage for functionality that native NSAttributedString can provide, which may be unnecessary for minimalist projects or those avoiding third-party libs.

Swift Version Constraints

Requires Swift 4.0+ and Xcode 9.0, which could hinder adoption in legacy projects stuck on older Swift versions or tools.
