Danie1s/Tiercel

Tiercel is an iOS download management framework that handles concurrent file transfers, caching, and task state persistence. It provides core capabilities for resume data parsing, file validation, and thread-safe concurrency control. The system includes a demo application to showcase these features and is supported by unit tests for state management and session recovery.

This change introduces the foundational components of the Tiercel download engine within the Sources/General directory. It adds a new Cache class for managing persistent download paths and temporary files, alongside a DownloadTask class that handles resume data parsing (including legacy NSKeyedArchive formats) and file validation. The update also includes a suite of utility extensions for hashing (MD5, SHA1, SHA256, SHA512), safe main-thread execution, and disk space checking, as well as concurrency primitives like UnfairLock, Debouncer, and Throttler to support thread-safe state management.

Sources/General · high confidence

This change introduces the Tiercel framework for iOS, providing a complete download management system. The Sources directory now contains the core implementation files, including TRManager for handling concurrent download tasks, TRDownloadTask for individual file transfers, TRCache for persistent storage and retrieval of task states, and TRCommon for shared utilities and status enums. The framework is initialized with an Info.plist and a public header (Tiercel.h) to expose the API for integration.

Sources · high confidence

The Example iOS demo application has been removed from the repository. This includes the Xcode project file, the main application entry point (AppDelegate), and all associated view controllers (ViewController1, ViewController2, ViewController3, DownloadViewController, ListViewController) and their corresponding UI assets (storyboards, xibs, and assets).

Example · high confidence

This change introduces the foundational Xcode project structure for the Tiercel library. It defines the build targets, source file groups (including core components like SessionManager, Task, and DownloadTask, as well as utility extensions), and workspace settings required to compile the framework. This establishes the baseline configuration for the library's build process.

Tiercel.xcodeproj · high confidence

The repository now includes a workspace file that groups the main Tiercel project and the Tiercel-Demo project, allowing developers to open and build both targets together in Xcode. This change establishes the project structure for local development and testing.

Tiercel.xcworkspace · high confidence

The iOS demo application has been reorganized into a new project structure under the Demo folder, featuring a new BaseViewController and specialized view controllers (ViewController1, 2, 3) to demonstrate different Tiercel download capabilities. This update introduces a new interface for managing multiple concurrent downloads with sorting and bulk operations, adds file validation (MD5) checks to single-file downloads, and includes a new launch screen with the Tiercel branding image.

Demo · high confidence

Added a new test suite (TiercelTests) that verifies task state transitions, session recovery from persisted state, and the rejection of operations on tasks not owned by the session manager.

TiercelTests · high confidence

The Tiercel download framework has been updated to version 3.3.0, raising the minimum supported iOS deployment target from 8.0 to 12.0 and upgrading the Swift language version from 4.0 to 5.0. This change also updates the source file glob pattern to include nested Swift files and introduces a Swift Package Manager manifest for the library.

• Ambiguous intent between download and start. 'download' creates a new task, while 'start' can either create a new task (from URL) or resume an existing one (from DownloadTask). This dual behavior for 'start' is confusing compared to the explicit 'download' method. Additionally, 'fetchTask' exists to retrieve an existing task, but there is no explicit 'resume' method, forcing users to use 'start' with an existing task object, which is semantically unclear.
• Coverage not measured — Swift suite
• Dependency hygiene PARTLY measured — SwiftPM pinning read, dependency currency NOT established
• Redundant overloads for URLConvertible vs DownloadTask. Similar to the Cache inconsistency, SessionManager exposes separate overloads for URLConvertible and DownloadTask for suspend, cancel, and remove operations. Since DownloadTask likely contains the URL or can be converted, and URLConvertible is a broader protocol, these overloads duplicate intent and increase maintenance burden without adding significant value.
• Redundant overloads for URLConvertible vs String. The API exposes separate method signatures for String and URLConvertible inputs for the same logical operations (getting path, URL, or checking existence). Since URLConvertible is a protocol that String conforms to, the String-specific overloads are redundant and create unnecessary API surface duplication.
