ReerKit
A comprehensive collection of Swift extensions and utilities for iOS, macOS, tvOS, watchOS, and Linux development.
What is ReerKit?
ReerKit is a native Swift framework that provides a wide array of extensions, syntactic sugar, and performance improvements for system types, UIKit, and Cocoa classes across Apple platforms and Linux. It enhances development productivity by offering convenient methods and utilities that simplify common tasks while maintaining type safety and avoiding naming conflicts.
Swift developers building applications for iOS, macOS, tvOS, watchOS, visionOS, or Linux who want to extend native types and frameworks with safe, convenient utilities. It's particularly useful for developers who frequently work with data structures, concurrency, property wrappers, and UI enhancements.
Developers choose ReerKit because it provides a comprehensive, non-intrusive toolkit that follows Swift conventions, uses a unique 're' infix to prevent naming conflicts, and offers a pragmatic collection of extensions and utilities that are not available in the standard library, such as weak reference containers, lock encapsulations, and dynamic member lookup for dictionaries.

Swift 基础库. A collection of Swift extensions and utilities.
Use Cases
Best For
- Adding type-safe extensions to Swift's standard library and Apple frameworks without naming conflicts using the 're' infix.
- Implementing common data structures like BinaryTree, Tree, LinkedList, Queue, Stack, OrderedSet, and OrderedDictionary in Swift projects.
- Managing concurrency and thread safety with utilities like MutexLock, ReadWriteLock, Synchronizing, and UnfairLock.
- Applying property behavior control with property wrappers such as Clamped, Locked, Rounded, RWLocked, and Trimmed.
- Accessing dictionary contents using dot notation via dynamic member lookup for cleaner code.
- Handling weak references with automatic cleanup using WeakSet and WeakMap containers.
Not Ideal For
- Projects aiming to minimize third-party dependencies for reduced maintenance and smaller binary sizes
- Teams already heavily using Swift's Combine framework or async/await for concurrency, as ReerKit's lock utilities may overlap
- Developers relying exclusively on Swift Package Manager for building iOS/macOS/watchOS apps, due to its unsupported platform limitations
- Applications requiring UIKit support on iOS versions older than 12.0, as ReerKit's minimum iOS target is 12.0
Pros & Cons
Pros
All extensions use the 're' infix (e.g., '123'.re.md5String) to prevent naming conflicts with existing methods, ensuring clarity and safety as highlighted in the README examples.
Includes implementations like BinaryTree, OrderedSet, and OrderedDictionary, which are not in Swift's standard library, providing ready-to-use solutions for complex data handling.
Offers MutexLock, ReadWriteLock, and other encapsulations for thread-safe operations, simplifying concurrency management without boilerplate code.
Supports Apple platforms (iOS 12.0+, macOS 10.13+) and Linux (Ubuntu 14.04+), making it versatile for both client and server-side Swift development.
Cons
The README explicitly states Swift Package Manager does not support building for iOS/tvOS/macOS/watchOS applications, which is a significant limitation for modern Swift projects using SPM.
The mandatory 're' infix on all extensions can make code more verbose and less idiomatic compared to standard Swift patterns, potentially hindering readability.
Documentation is primarily via DocC or a downloadable archive, with a Chinese version available, which may pose language barriers or lack real-time updates compared to online, searchable docs.
