GCD (Grand Central Dispatch)

Grand Central Dispatch (GCD) is a technology used in Apple devices to help computers manage multiple tasks efficiently. It organizes work into small, manageable chunks and assigns them to available processor cores, ensuring tasks run smoothly without slowing down the system. GCD simplifies how developers write programs that perform many operations at once, such as handling user interactions, updating visuals, or processing data, by automatically balancing the workload. This results in more responsive apps and better overall performance, as GCD optimizes the use of the device’s processing power seamlessly behind the scenes.
