[SOLVED] UITest keeps failing to tap alert view when running on simulator

UITest keeps failing to tap alert view when running on simulator

I have created a series of UI Tests that run fine on a device but when using a Simulator, I cannot tap alert view buttons.

 let alert = app.alerts["Continue"]
 alert.buttons["Yes"].tap()

Instead, it crashes with

Find: Descendants matching type Button
t =    10.17s     Find: Elements matching predicate '"Yes" IN identifiers'
t =    10.18s     Check for interrupting elements affecting "Yes" Button
t =    10.19s     Requesting snapshot of accessibility hierarchy for app with pid 14120
t =    10.21s     Find: Descendants matching predicate identifier == "NotificationShortLookView" OR elementType == 7
*** -[__NSArrayM insertObject:atIndex:]: object cannot be nil (NSInvalidArgumentException)

I believe (and hope) this is an Xcode 13 bug and may be fixed in an update soon. Does any one know a way around this?

Solution

Turns out this is only an issue when running on an iOS 12 simulator. It is ok when running on an iOS 15.4 simulator.
