Unstructured Concurrency in Action

Now that you have a better understanding of what unstructured concurrency is, and you finally learned what the Task object is, we can start writing some sample code to better understand how it all works.

We will work and modify the project we created in the last chapter – the ImageDownloader project .

The project worked perfectly fine, but it had two main issues that I’d like to address:1.

When the app launched, it showed a ProgressView in the center until all images were done downloading. This means if we had a lot of images or they were really big, the ProgressView would be shown for a very long time. Once the images were done downloading, the view would refresh and show all the images at once.
