A Swift library extending promises with progress tracking, pause, cancel, and retry capabilities.
SwiftTask is a Swift library that extends the promise pattern with additional control flow features like progress tracking, pause, cancel, and retry functionality. It solves the problem of managing complex asynchronous operations in Swift applications by providing a unified API that goes beyond basic promise fulfillment and rejection.
Swift developers building applications that require robust asynchronous operation management, particularly those needing features like progress updates, cancellable tasks, or automatic retries for network requests.
Developers choose SwiftTask because it combines the familiarity of promises with essential real-world features missing from basic promise implementations, eliminating the need to manually implement progress tracking, cancellation, or retry logic across their codebase.
Promise + progress + pause + cancel + retry for Swift.

Provides built-in progress updates for ongoing tasks, as demonstrated in the Alamofire example where download progress values are passed and monitored.
Supports pause, resume, cancellation, and automatic retries via configurable closures, offering robust management beyond standard promises.
Uses .then, .success, and .failure methods similar to JavaScript promises, making it accessible for developers already comfortable with promise chaining.
Includes Task.all, Task.any, and Task.some for combining multiple async operations, enabling flexible parallel execution strategies.
Configuring pause, resume, and cancel requires manual closure definitions, as shown in the basic example, adding boilerplate and complexity.
Installation instructions point to a wiki page, and the project targets Swift 2.0, indicating potential maintenance issues and compatibility gaps with newer Swift versions.
Compared to mainstream libraries like PromiseKit, SwiftTask has fewer adopters, which may result in scarce resources and slower bug fixes.
