Nuke 12.7 (Beta 1)

on GitHub

🐛 Call for Testing. This release contains some major internal changes to the core APIs. Please help with testing the newly introduced and the existing ImagePipeline APIs, and report any issues before it gets shipped.

This release contains some major improvements to the Structured Concurrency support and introduced a re-engineered ImagePipeline.

• Add previews: AsyncStream<ImageResponse>, progress: AsyncStream<Progress>, image: PlatformImage async and reponse: ImageResponse async directly to ImageTask and deprecate AsyncImageTask. These APIs have zero cost unless you use them.
• Add ImageTask.Event and add events: AsyncStream<Event> to ImageTask for observing all events associated with the image loading.
• Improve the support for AsyncStream: a new stream is created every time you access the respective property to make it easier to have multiple consumers.
• Add ImagePipelineDelegate/imageTask(:didReceiveEvent:pipeline:) and deprecate the previous methods it replaced (context: these methods were introduced in Nuke 11.0 as the initial and misguided attempt at Structured Concurrency support that tried to borrow from the URLSession API design)
• (Internal) Rework ImagePipeline that accumulated a lot of cruft after the introduction of data tasks, Combine, Async/Await, and AsyncStream support in the previous releases.
• Deprecate ImagePipeline/loadData(with:) and ImagePipeline/data(with:) methods that accept URL as parameters – use the ImageRequest variants instead (these are rarely used and low-level APIs that don't require convenience variants)
• Remove @discardableResult from ImagePipeline/data(with:) async throws – it was never meant to be there
• Rename ImageTask/progress to ImageTask/currentProgress (warning: this is a small breaking change in the API)
• Fix some of the Strict Concurrency Checking & Swift 6 warnings preparing for the upcoming Swift releases
• Fix documentation for AsyncImageTask/previews that was previously specifying that it was delivering the previews and the final image – it's only the previews.
