LNITaskList

Implementation of "Promises" in Swift

Do you like what q does, and would like it for Swift? In other words, you want to run a set of asynchronous tasks sequentially, while avoiding the Pyramid of Doom?

LNITaskList helps you do exactly that. Take the LNITaskList.swift from this project and add to your project. Then, you can write the steps as follows:

let taskList = LNITaskList()
taskList.onSuccess {
  // What should happen on success - if ALL steps succeed
        }.onFailure {
  // What should happen on failure - if ANY step fails. All subsequent steps are skipped.
        }.addStep {
            // Do whatever you like. Pass taskList as a parameter to the async operation
        }.addStep {
            // As many as you like. The only common factor is taskList, defined above
        }.start()

In all the asynchronous "steps", call

taskList.markDone(true) // When the async step succeeds

or

taskList.markDone(false) // When the async step fails

That's it! Take a look at the demo app for more information.
