xcode: Timestamped Event Matching Error: Failed to find matching element

Question

I'm trying to record some XCUITesting functions. I get this error.

Timestamped Event Matching Error: Failed to find matching element 

Is this an Xcode bug and/or issues with the complexity of my UI?

Answer 1

I was having the same problem for a long time on a very complex app as well: The key is all in isAccessibilityElement being set to YES. UI testing and accessibility go hand-in-hand. The way I think about it is that the device needs to be able to interact with the element, since ostensibly, the user wouldn't be able to.

I did this twice:

1. In cellForRowAtIndexPath - cell.isAccessibilityElement = YES

2. In awakeFromNib in a UITableViewCell subclass - self.isAccessibilityElement = YES

Hope that helps, and good luck!

Answer 2

Try manipulating with items isAccessibilityElement property. As far as I know containers like tableView should have this property set to NO in order to items contained inside them be accessible

Quote from https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIAccessibility_Protocol/#//apple_ref/occ/instp/NSObject/isAccessibilityElement :

Assistive applications can get information only about objects that are represented by accessibility elements. Therefore, if you implement a custom control or view that should be accessible to users with disabilities, set this property to YES. The only exception to this practice is a view that merely serves as a container for other items that should be accessible.
