fix(ios): include elements with accessibilityIdentifier in dump ui regardless of type - #342
Conversation
handleScreenRecord fired the DeviceKit/ReplayKit startup in a goroutine and returned status:"recording" immediately, racing any device command sent right after against the still-in-progress (and sometimes failing) broadcast picker click on real iOS devices.
…gardless of type Elements tagged with an explicit accessibilityIdentifier (e.g. container XCUIElementTypeOther views) were dropped by the type whitelist in filterSourceElements, hoisting their children to the parent level. If the developer put an id on an element, it belongs in the dump — matching Android, which keeps containers that carry a resource-id or content-desc. Fixes #341
📝 WalkthroughWalkthroughScreen recording now reports startup readiness through channels and callbacks before success acknowledgment. iOS AVC startup uses dedicated DeviceKit forwarding helpers. iOS UI dumps retain accessibility-identified containers with nested children.

Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to This PR changes iOS UI hierarchy output and recording behavior. Tagged containers without a raw identifier can still be omitted, while recording requests may report success before startup is confirmed and timeout cleanup can permit overlapping captures; these can produce incorrect page sources and unreliable or conflicting recordings.

Preserve label-only containers and add regression coverage.
The override currently accepts only a non-empty RawIdentifier. An XCUIElementTypeOther container with a non-empty Label and nil RawIdentifier is still rejected, causing its children to be hoisted and violating the hierarchy requirement for identified or labeled containers.
Extend the condition to accept a non-empty Label, and add a label-only fixture with Name nil that verifies the container and its children remain nested.

Do not clear a recording that is still running.
Line 1160 removes the session after timeout, but it does not close session.StopChan or wait for session.Done. The command goroutine can later start recording. A new request can then start a second capture on the same device.
On timeout, request stop and retain the session until the command exits. Clear the session only after session.Done is received.

Summary
Fixes #341.
filterSourceElementsused a pure type whitelist, soXCUIElementTypeOthercontainer views tagged with anaccessibilityIdentifierwere dropped from the formatteddump uioutput and their children hoisted to the parent level — breaking parity with Appium page source and with Android, which keeps containers that carry aresource-idorcontent-desc.The rule is now: if the developer put an id on an element, it appears in the dump, regardless of element type. Children of such containers stay properly nested.
Verified on simulator
