There is no exact equivalent, but you have several possibilities to execute code in parallel: e. g. Grand Central Dispatch, NSOperationQueue, and other.

@user2273146 Yes you can, you can create a serial or a concurrent queue – Ahmad F Oct 24 '16 at 06:30

Actually, there more than just one concurrency technique for working with iOS, but I suggest to read about the GCD (Grand Central Dispatch) world.

Working with DispatchQueues is very easy now (after releasing Swift 3), you can check this answer to know how you can simply create one.

Also, you might want to check NSOperationQueue.

Hope this helped.

The simplest/quickest solution in Swift 3.0 is:

DispatchQueue.main.async {
   // your code goes here
}

That executes your code on the main thread asynchronously.
