Looks good 👍 Just a minor request to align with the convention we agreed on the RFC

[maxep]

/change-request We aim to hide these interfaces from Swift autocompletion. As stated in the RFC, the interfaces should read:

@objc(DDWebViewTracking) @_spi(objc)
public final class objc_WebViewTracking: NSObject

[ncreated]

Thanks for flagging this 💪! I forgotten that we established this convention. Now everything should be up-to-date, including the PR comment and +objc file location ✅.
