Can you describe some scenarios where this is useful? Is it largely for letting user to do things like manually clearing cookies or viewing their attributes, or are there other uses like being able to programmatically set cookies in a browser session? What are your use cases for this?

• Yes, user-facing cookie clearing is part of the use case (along with other data types)
• For us, programmatic cookie management is used for session handoff and synchronization when authenticated traffic needs to be moved outside the original WebView context (background downloads for example).

Unrelated but I haven't been able to compile the SkipUI dependency after it was updated to 1.50.0. I had to force the version back to (.package(url: "https://github.com/skiptools/skip-ui.git", exact: "1.49.1")) in order to compile in XCode. It's a very recent change, and I'd rather not try to fix it without the proper context!

Here is the error:

...
skip-ui/Sources/SkipUI/SkipUI/UIKit/UserNotifications.swift:675:39: error: This API is not yet available in Skip. Consider placing it within a #if !SKIP block. You can file an issue against the owning library at https://github.com/skiptools, or see the library README for information on adding support

That's odd. That error isn't why the CI is failing, which is a different issue that only happens in the iOS build:

Testing failed:

	Call to main actor-isolated static method 'androidRemovalBucketNames(for:)' in a synchronous nonisolated context
Test session results, code coverage, and logs:
	Call to main actor-isolated static method 'androidRemovalBucketNames(for:)' in a synchronous nonisolated context
	Call to main actor-isolated static method 'webKitDataTypes(for:)' in a synchronous nonisolated context
	Testing cancelled because the build failed.

For the calendar.nextDate issue, that was a new API that came in with skip-foundation 1.3.13, so you may just need to make sure your local checkout is up to do (e.g., delete your Package.resolved locally and/or run Xcode's File/Packages/Update to Latest Package Versions).

Yes the calendar.nextDate() compilation problem was happening in my local environment - fixed now (thanks for the tip)

The CI tests passed after the latest adjustments

Next, I'm planning to add profile support to skip-web, to power featues like transient profiles for private browsing (similar to Safari's Private Tabs). Currently, all webviews share a single cookie store on both Android + iOS.

Happy to fold this into the current PR rather than open a new one — let me know!

I'll merge this one and you can open a new PR for profiles so we can keep that size of the PRs small(-ish).

This is a great feature, thanks!
