Welcome to swift-corelibs-multitasking – the state-of-the-art library engineered to transform concurrency and parallelism in Apple's ecosystem. Leveraging the power of Grand Central Dispatch (GCD), this library brings advanced scheduling algorithms, superior thread management, and seamless integration with Swift’s async/await features to deliver unmatched performance and efficiency in multitasking operations.

• FairScheduler: Ensures equal execution opportunities for all tasks, preventing any single task from monopolizing resources.
• PriorityScheduler: Executes tasks based on assigned priority levels, allowing critical tasks to be processed first.
• DeadlineScheduler: Schedules tasks according to their deadlines, ensuring time-sensitive tasks are completed on time.
• LoadBalancer: Dynamically distributes tasks across available resources for optimal performance and efficiency.

• Thread Pooling: Efficiently manages thread creation and reuse to minimize overhead and improve performance.
• Thread Prioritization: Assigns priorities to threads to ensure that critical tasks get the resources they need.
• Real-time Monitoring: Continuously tracks thread performance and resource utilization to adapt to changing workloads.

• Async/Await Support: Full integration with Swift's async/await syntax for modern, asynchronous programming.
• Combine Framework Integration: Leverages the power of Combine to handle complex task coordination and data flow.
• Cross-Platform Compatibility: Supports macOS, iOS, tvOS, watchOS, and Linux, providing a consistent multitasking solution across platforms.

• Real-time Metrics: Tracks performance metrics in real-time to identify bottlenecks and optimize task execution.
• Detailed Logging: Provides extensive logs of task execution and system performance for debugging and analysis.
• Customizable Alerts: Configures alerts for specific performance thresholds to proactively address potential issues.

• Xcode 12.5 or later
• Swift 5.5 or later

The following steps were executed on a clean checkout in this environment:

swift build
swift test
swift run multitasking-demo

• If swift build reports Package.swift missing, ensure you're running the commands from the repository root after pulling the latest changes.
• On Linux environments without Apple's Combine framework, the package falls back to an included lightweight Combine shim so no extra dependencies are required.
• If tests hang around threading, re-run with swift test --disable-sandbox to ensure threads can be created freely in restricted environments.

swift build
swift test
swift run multitasking-demo

swift run multitasking-demo --demo

./scripts/verify.sh

• Sources/Multitasking: Core library implementation.
• Sources/multitasking-demo: Demo CLI executable.
• tests/core: XCTest suite for core functionality and observability utilities.
• docs: Architecture, demo, security, and baseline notes.
• scripts: Developer tools (verify, lint, doctor).

• Additive enhancements are opt-in to avoid changing default behavior.
• Observability utilities run in-process and do not require external services.
• Demo mode uses a temporary directory and avoids network access.
