Is it possible to implement threads in Swift?

Yes, implementing concurrency is possible in Swift. Various approaches are used:

• Grand Central Dispatch (GCD) — a low-level API for working with task queues, allowing asynchronous and parallel code execution.
• Operation and OperationQueue — a higher-level mechanism for managing tasks with dependency management.
• Swift Concurrency (async/await) — a modern way to work with asynchronous code, introduced in Swift 5.5.

Example of using GCD:

DispatchQueue.global(qos: .background).async {
    // Background task
    print("Running in background")
    DispatchQueue.main.async {
        // UI update on the main thread
        print("Updating UI")
    }
}
