🔵 Running Tasks in Parallel in Swift​

This blog post explores various methods for running tasks in parallel using Swift. It covers both traditional tools, such as Grand Central Dispatch (GCD) and operation queues, and newer techniques introduced with Swift's structured concurrency API. The post includes detailed code examples and highlights the benefits of each approach, particularly focusing on the ability to limit the number of concurrent operations for better performance and resource management.
