Well, if you want to find the first TextView element from the first cell, you would use:
“tableViews()[0].cells()[0].textViews()[0]”.
Or even better, if you want to find the specific textview element by something else than index, than you can use IOS Predicates.

They are a bit tricky and not that well documented, true.
