UIFontComplete
A Swift library providing type-safe font management with code completion for iOS and tvOS.
What is UIFontComplete?
UIFontComplete is a Swift library that provides type-safe font management for iOS and tvOS apps. It replaces string-based font names with an enum, eliminating runtime errors from typos and enabling Xcode code completion. The library supports both system and custom fonts, and works with both UIKit and SwiftUI.
iOS and tvOS developers using Swift who want to avoid font-related runtime crashes and improve development speed with autocompletion.
Developers choose UIFontComplete because it turns font management from an error-prone string-based task into a type-safe, autocomplete-friendly experience, reducing bugs and saving time during UI development.
Overview
Font management (System & Custom) for iOS and tvOS
Use Cases
Best For
- Eliminating runtime crashes from mistyped font names in iOS apps
- Speeding up UI development with Xcode autocompletion for fonts
- Building type-safe UI components that reference system fonts
- Integrating custom fonts with the same safety as system fonts
- Developing cross-platform iOS/tvOS apps with consistent font handling
- Migrating UIKit font code to SwiftUI while maintaining type safety
Not Ideal For
- Objective-C-only iOS projects, as it's designed for Swift and doesn't provide Objective-C compatibility
- Apps that load font names dynamically from servers or configuration files, since the enum-based approach is static at compile time
- Teams already using a mature, custom font management system, where adding this library would introduce redundancy
- Cross-platform projects using frameworks like React Native or Flutter, as it's specific to iOS and tvOS
Pros & Cons
Pros
Replaces error-prone string-based font names with an enum, eliminating runtime crashes from typos, as demonstrated by the comparison between UIFont(name:size:) and UIFont(font:size:).
Leverages Xcode's autocomplete to suggest font names as you type, speeding up development, with a GIF in the README showing real-time suggestions.
Allows adding custom fonts via the FontRepresentable protocol, enabling the same type-safe experience as system fonts, with a clear example in the README.
Works seamlessly with SwiftUI's Font type, making it easy to adopt in modern iOS development without switching between UIKit and SwiftUI APIs.
Includes all iOS and tvOS system fonts as enum cases, ensuring developers have access to every built-in font without missing any.
Cons
Only supports iOS and tvOS, not macOS or watchOS, requiring separate solutions for full Apple ecosystem projects.
Requires creating a custom enum for each font via FontRepresentable, which can be tedious and error-prone when managing many custom fonts, as shown in the example.
Font names are defined statically at compile time, making it unsuitable for apps that need to load fonts dynamically from resources or remote sources.
Requires Swift 4.0 or higher, which may not be compatible with legacy projects using older Swift versions, as indicated by the Swift 5.0 badge.
