NukeExtensions with async/await

[BAUMANEZ]

Because of task.onCancel being internal I cannot resume in continuation and that is why I get a continuation misuse warning produced by xcode. It also happens as loadImage in NukeExtensions does not always call its completion

Unfortunately, in our project we are unable to use LazyImageView. It seems to me that all I need is completion being called when task is cancelled

Any ideas how I can fix this problem? Thanks for your help in advance

P.S. Behaviour I want to achieve: load image into imageView automatically by NukeExtensions with given preprocessors and also await until the end of this process

Hi,

I agree that ideally, there should be a way to observe the task cancellation, which is not currently the case, at least not using the public APIs. I considered updating the completion closure to include the .cancelled error case, but that can disrupt too many apps that use Nuke. My long-term plan is to deprecate and eventually remove completion-based APIs.

I would suggest adding a new Async/Await APIs to NukeExtensions. I might be missing something now, but I don't think it requires onCancel to be publicly exposed. Ideally, the loadImage(with:into:) method should be async/await and use the ImagePipeline async/await API internally. The completion-based API should be added on top of the async/await APIs, making it easy to remove in the future.
