The open-source port of Grand Central Dispatch (libdispatch), Apple's concurrency library for executing concurrent code on multicore hardware. It provides the portable C/pthread-based implementation of the dispatch API on Linux and other non-Darwin platforms, bundled with Swift releases since Swift 3.

Use cases

• run concurrent tasks on multicore hardware in Swift on Linux
• use Grand Central Dispatch queues outside Apple platforms
• schedule work on serial and concurrent dispatch queues
• build Swift core libraries that rely on libdispatch
• port Darwin dispatch-based code to Linux

When to choose

• you need GCD-style concurrency in Swift on Linux or other non-Darwin platforms
• you want a proven, low-level C concurrency primitive library
• you are building or maintaining Swift core libraries

When to avoid

• you are on Darwin/macOS, where the system libdispatch is already provided
• you prefer higher-level structured concurrency (Swift async/await, task groups)
• you need a kernel-integrated scheduler with system-wide load balancing
