It doesn't look like UIAccessibilityPostNotification is available on WatchOS:

┌── [ /Applications/Xcode-beta.app/Contents/Developer/Platforms/WatchOS.platform  ]
└─» ag UIAccessibilityPostNotification

119:                       _UIAccessibilityPauseAssistiveTechnologyNotification, _UIAccessibilityPostNotification,

Here are what the headers look like for iPhoneOS:

Thank you for investigation. I understand. I'll wait it is supported for WatchOS.
