ImageRequest userInfo dictionary `Any` type for value allows unsupported types for imageIdKey

[sean-escendant]

My project is using signed URLs for images and Nuke 12.4. I followed the documentation to use a custom image id key. Initially I had passed a URL, with query parameters stripped, as the custom key but testing showed that the cache wasn't working as expected. Only when I changed the key to a String, as in the documentation example, it started working as expected.

It seems some trade offs were made in the API design from Nuke 9 to 10 which introduced this, hopefully you can find a way to keep the API strongly typed otherwise a clear notice in the documentation as to what are the supported types for imageIdKey.

Hey, @sean-escendant. Thanks for raising this. I think it's a valid concern, and this change also had other implications: a slight impact on performance and potentially higher memory use if one of the user info keys is used.

How would you suggest approaching it?

I'm planning to work on version 13.0 soon, and it would be a good time to introduce any breaking changes if needed.
