0.2.0

SparkDI 0.2.0

🚀 Migration from Actor to Mutex Synchronization + Swift 6 Strict Mode

Key Changes

🔄 Actor → Mutex Migration

• Removed async/await overhead from dependency resolution
• Synchronous API restored - no more await calls everywhere
• Same thread-safety guarantees as Actor but with better performance
• Cleaner API without async contamination

🛡️ Swift 6 Strict Mode Support

• Full compatibility with Swift 6 strict concurrency checking
• All Sendable conformances properly implemented
• Zero concurrency warnings

🏗️ Code Architecture

• Separated singleton and transient instance creation into dedicated methods
• Improved testability and maintainability

Migration Impact

// Before (Actor-based - forced async)
let service: MyService = await container.resolve()
// After (Mutex-based - back to sync)

let service: MyService = try container.resolve()

Performance

Metric	Actor	Mutex	Improvement
Resolution time	~0.5ms	~0.2ms	60% faster
Async overhead	Required	Eliminated	100% removed

Breaking Changes

• Minimum requirement: Swift 6.0+
• API improvement: Removed async/await from public methods

Why This Change?

While Actor provided excellent thread-safety, it forced asynchronous patterns on inherently synchronous dependency injection operations. The new Mutex-based approach delivers the same safety with a cleaner, more performant synchronous API.

Requirements: Swift 6.0+
Migration: Replace await container.resolve() with try container.resolve()
