URL for cached image

[Patresko]

How do I get url of cached image if exist in cache?

I would like to show image in .quickLookPreview.

If you already knows the URL and didn't use a customized cache key or any image processor (ImageProcessor), then you can just use the methods in ImageCache to find out if an image is cached:

let cached = ImageCache.default.isCached(forKey: url.absoluteString)
