Xpath: By.xpath(".//XCUIElementTypeCell[.//XCUIElementTypeOther//XCUIElementTypeOther//XCUIElementTypeOther//XCUIElementTypeCollectionView]")
@iOSXCUITFindBy(iOSClassChain = "**/XCUIElementTypeCell/**/XCUIElementTypeCollectionView")
I don’t see a clear direct alternative to it, although one could try a sligtly simplified option like
**/XCUIElementTypeCell[$type == "XCUIElementTypeCollectionView"$]
That did the trick, thanks!
