Associating attributes with WebView RUM

[kabiroberai]

At the moment, RUM events sent through the Web View bridge (i.e. web views configured with WKUserContentController.trackDatadogEvents) don't include attributes defined via Global.rum.addAttribute. This is somewhere in between a bug report and a feature request but it'd be great if the iOS RUM attributes could be combined with the browser RUM attributes. Without this in place, Datadog appears to non-deterministically(!) nuke iOS attributes from app sessions because it looks to be using a heuristic (last/most frequent view?) to determine which set of view attributes it should apply to the session as a whole.

I'm currently getting around this with a hacky redefinition of window.DatadogEventBridge.send but I have a feeling an in-tree fix could be a lot cleaner, by merging the browser and iOS attributes in DefaultWebRUMEventConsumer.map(event:with:).

Thanks for reporting this @kabiroberai. I will double check with the team and get back to you as soon as I can.

Hello 👋

I'm closing this issue due to inactivity. For the record, you are correct that iOS global RUM attributes are not currently injected into browser events, and we have no plans to change this behavior at this time. Thank you for bringing this to our attention though.

Feel free to reopen the issue if you have more questions or need additional clarification on this topic.
