AnyTask

  • An AnyTask can be used as a generic Task object. You have to pass it a execute block when it’s initialized and that will be called when it’s time to execute the task.

    AnyTasks schedules execution blocks on TaskManager.shared.

    Swift

    public class AnyTask<T> : Task

  • Creates a task out of an expression and returns it as an AnyTask

    let x = task(someLongOperation())

x.async { result in
   // stuff
}

// or

let result = x.await()

    Declaration

    Swift

    public func task<R>(closingOver closure: @autoclosure @escaping () -> R) -> AnyTask<R>

    Parameters

    closingOver

    the expression to create a task out of

  • Creates a task out of a function that has a done callback. I.e.

    let f = { (done: @escaping () -> Void) -> Void in
   DispatchQueue.global(qos: .unspecified).async {
       // Do some long running calculation
       done()
   }
}
let t = task(executing: f)

    Declaration

    Swift

    public func task(executing block: @escaping (@escaping () -> Void) -> Void) -> AnyTask<Void>

    Parameters

    executing

    an asynchronous function that has a done callback as it’s only parameter. The done callback must be called when the asynchronous operation completes.

  • Creates a task out of a function that has a done callback with a specific signature

    Parameters
