Skip new tasks if the queue is not empty. Swift












1














I have a piece of code that spams long running tasks 5-6 times per second. Each task takes some time to finish. I want to ignore all the other tasks while 1 is being executed. After it finishes a fresh one should take its place.



There are a bunch of tools being used for concurrency in Swift 4.2. What would work the best?

          For solving of this problem you can use GCD or Operation. In case that you have describ I would use Operation. Using this approach you can have a bit more user friendly control over Operation that are executing (stoping, cancelling....).



          Small example:



          let queue  = OperationQueue()
          
queue.maxConcurrentOperationCount = 1
          

          
queue.addOperation { print("🤠") }
          
queue.addOperation { print("🤓") }
          
queue.addOperation { print("👺") }


          In this case operations are executed one by one.
