A pure Swift iOS download framework for background downloads, relaunch recovery, resumable transfers, and task management.
Tiercel is a pure Swift iOS download framework that simplifies implementing robust download functionality in iOS apps. It builds on Apple's `URLSession` to provide background downloads, relaunch recovery, resumable transfers, and advanced task management, solving the complexity of handling long-running download workflows.
iOS developers building apps that require reliable file downloads, such as media streaming apps, offline content readers, or any application needing robust background download capabilities.
Developers choose Tiercel because it offers a production-ready, higher-level API over raw `URLSession`, with built-in features like persistence for relaunch recovery, batch operations, and network policy controls, reducing boilerplate and increasing reliability.

Provides a higher-level API over URLSession for background downloads that leverage native iOS behavior, simplifying implementation compared to raw URLSessionDownloadTask.
Automatically persists task metadata and resume data to disk, enabling downloads to recover after app relaunches, which is essential for production reliability.
Offers built-in operations for starting, suspending, canceling, and batch downloads, with progress, speed, and validation callbacks out of the box.
Configurable settings for cellular, constrained, and expensive networks allow developers to tailor download behavior based on real-time conditions.
Engineered for long-running flows in multi-threaded environments, ensuring stability and performance in complex iOS applications.
Limited to iOS only, making it unsuitable for cross-platform projects or apps targeting other platforms like macOS without significant modification.
Relies on closure-based callbacks, which can feel outdated compared to modern Swift concurrency with async/await, potentially complicating error handling and code readability.
Requires wiring completion handlers from AppDelegate for background session support, adding boilerplate and complexity that isn't fully abstracted away.
Introduces an external framework dependency and disk I/O for persistence, which might be unnecessary overhead for apps with simpler download needs or strict size constraints.
