我尝试使用最新的XCode版本（7.2）在集合视图上记录滑动。 XCode立即崩溃：
UNCAUGHT EXCEPTION (NSInternalInconsistencyException): ancestorFinder is not being processed by childNodeFinders.
currentNodeFinder:<XCUIRecorderNodeFinder: 0x7fed29660780>allowDirectChildrenMatches:0, targetElementType:XCUIElementTypeOther, ancestorNodeFinderMatch:0x7fed315a53e0
ancestorFinder:<XCUIRecorderNodeFinder: 0x7fed2967b800>allowDirectChildrenMatches:1, targetElementType:XCUIElementTypeCell, ancestorNodeFinderMatch:0x7fed315aa580
有人可以告诉我如何在集合视图上执行滑动以便我可以创建我的UI测试吗？
