Mutex & Synchronization — Thread-Safe Primitives
Low-level synchronization primitives for when actors are too slow or heavyweight.
When to Use Mutex vs Actor
| Need | Use | Reason |
|---|---|---|
| Microsecond operations | Mutex | No async hop overhead |
| Protect single property | Mutex | Simpler, faster |
| Complex async workflows | Actor | Proper suspension handling |
| Suspension points needed | Actor | Mutex can't suspend |
| Shared across modules | Mutex | Sendable, no await needed |
| High-frequency counters | Atomic | Lock-free performance |
API Reference
Mutex (iOS 18+ / Swift 6)
