What are NS Threads?

NS Threads are part of the Foundation framework in Apple's macOS and iOS development environments, providing a way to manage and perform concurrent tasks. Each NSThread object represents a single thread of execution, allowing developers to run code in parallel with the main thread, which is crucial for keeping user interfaces responsive during long-running operations. NSThreads can be created, started, suspended, and terminated, offering a high level of control over multithreading in applications. However, with the introduction of higher-level abstractions like Grand Central Dispatch (GCD) and Operation Queues, the use of NSThread has become less common in modern development.
