In order to track iOS editor/editing activity we will need to start planning to send edit event tracking to the global EditAttmptStep schema. Just want to get the ball rolling so this is on engineering radar.

We can replicate the Android editing data that is currently being sent to this schema with the following actions:
init (start)
saveAttempt
saveSuccess
saveFailure

Note: For edits initiated while highlighting text we will use an additional first step highlightEdit at beginning of funnel.

iOS data will also need to have value integration = ios-app-phone (or ios-app-tablet) and numeric page_ns and revision_id value sent with each event.
