I have a method with a task queue that calls another method with a task queue

I'm guessing this is because they are on the same queue?

I have 1 2 a b 3

It executes 1 2 a 3 b

I'm not sure if this is an actual issue but I was wondering. When is the right time to call .run() on a queue? In your Readme, you always called it after you've added all the tasks you wanted to add. Is it possible to call .run() say in a class initialiser and keep adding tasks to it AFTER. So that it just keeps processing tasks as they come (one after the other)?

And if they do, for how long?

It seems to me that the queue is subject to the limited time given by iOS to tasks created by application.beginBackgroundTaskWithExpirationHandler, since there is no additional setup required to use it.

Hi,

I don't know why but I am using Reachability to pause and resume the queue, so I do paused = true when there is no internet connexion, then when internet is back, I do paused = false and run.

They are task in queue, but for some reasons they are never called, and the finish of the run block is never called. Any idea?

Thanks

I used the api mentioned in the documentation but the request and response are not in the order they are random its like not waiting for the previous response before executing next .

Hi. I had compile error because TaskQueue class has no public init method.

I commented at https://github.com/icanzilb/TaskQueue/commit/0ed1061a1df2559914499df73629fca8099d2881.

Please check.

It'd be great if there is a way to say smth like:

queue += { code executed on same thread as queue was created on }

queue +=! { code to be executed on main thread }

queue +=? { code to be executed on bg thread }

• Use Sources and Tests directories
• Add a tests target for TaskQueue project
• Rename demo app to iOSExample and include it in the workspace
• Other general cleanup

I updated the project settings to make it build on macOS, tvOS, and iOS through the existing scheme. That means that it now works with users who are using Carthage for those platforms too.

I also added a pauseAndResetCurrentTask function that I've been using but I can remove that if you don't want that as part of the library.

Other things:

• Updated SWIFT_VERSION to 4.0
• Removed code signing as it's unnecessary
• Updated Podspec to specify deployment_targets for iOS, macOS, and tvOS
• Set APPLICATION_EXTENSION_API_ONLY = YES

Basically can I nest adding to the task queue or is that going to mess things up?

queue.tasks +=~ { result, next in queue.tasks +=~ { result , next in print("foo") next(nil) } next(nil) }

Is it possible to have an active queue available that I feed tasks I need to run in order. In my case I don't have the tasks ahead of time before I call .run. Is that possible?

Hi there! Thanks for this excellent library. I've been a longtime user, and am thrilled to contribute back an enhancement that would've saved me a ton of duplicated logic in my tasks over the years.

I've long been including UI updating logic in my tasks, and have wanted a view on the queue's state so I can more directly inform the user about what's happening in the program.

Let me know if there's more I can do to help this code land 😉

The following is the setup and the issue I am running into:

• Singleton object contains a TaskQueue object.
• At some point, when deemed correct(attempt at unauthorized use), the TaskQueue object is cleared using remove all
• Afterwards, when trying to add tasks to TaskQueue object, tasks in the queue are not being run.

let queue = TaskQueue()

func init() {
     downloadStuff()
}

func downloadStuff() {
   queue.tasks += {[weak queue] result, next in

       myTask(completion: { success in
          if success {
               next(nil)
          }
          else {
             print("error out")
          }
       }

   }

   queue.run() {
       print("completed")
   }
}

func unauthorizedUse() {
     queue.removeAll()
}

func authorizedUse() {
     downloadStuff()
}
