In iOS 8, Apple introduces var accessibilityElements: [Any]?
.
func accessibilityElementCount() -> Int
func accessibilityElement(at: Int) -> Any?
func index(ofAccessibilityElement: Any) -> Int
What's the difference between them? Is the priority of var accessibilityElements: [Any]?
higher than the old methods?
