RUMM-1658 Manual instrumentation of SwiftUI actions

[maxep]

What and why?

Actionable SwiftUI components such as Button or NavigationLink are rendered in an opaque UIView subclass: CGDrawingView*. The SDK's auto-instrumentation of UIEvents is not able to capture information from the view to accurately log an action event.

Given the SwiftUI api, we have no way of providing an auto-instrumentation of actions so we have to provide a simple way for instrumentation User Actions manually.

*This is not true for all actionable components, Bar buttons or List items are respectively rendered in UIControl and UITableViewCell and are auto-instrumented by the SDK out of the box.

How?

We will provide a SwiftUI.View extension that allows tracking of Tap action by adding simultaneousGesture using a ViewModifier. The Gesture will then send User Actions events through the Global.rum.

Review checklist

• Feature or bugfix MUST have appropriate tests (unit, integration)
• Make sure each commit and the PR mention the Issue number or JIRA reference

I think this looks like a good way 👌. Left one question, but to my SwiftUI understanding it is not possible to make it more "automatic".

Actually, I will have to remove the .swipe instrumentation using SwiftUI.DragGesture. During the implementation of integration tests, I've noticed that the simultaneousGesture(_:) is not actually working and act as gesture(_:), so it will block any other interaction in the view.

👌 LG! Only wondering if RUMM-1764 is not a problem here - I don't remember the conclusion and if it impacts iOS or only Android.

I don't remember the conclusion and if it impacts iOS or only Android.

IIRC It was concluded that Android will align to iOS by removing side-effect detection on manual instrumentation.
