Appium + iOS automation : Error "Could not write domain com.apple.keyboard.preferences; exiting"

Question

Team, Everything was working and suddenly I observed all the tests started failing :( with following error :

Could not write domain com.apple.keyboard.preferences; exiting

What all I have tried :

1. First and foremost I checked Network
2. Then verified other system components such as Simulator, Appium server

They are set & working as expected. By any chance you have work around for this issue?

Answer 1

Working solution :

• I found this issue is intermittent.

sh "xcrun simctl shutdown $(xcrun simctl list devices | grep -m 1 'iPhone 12 Pro' |grep -E -o -i '([0-9a-f]{8}-([0-9a-f]{4}-){3}[0-9a-f]{12})')"

• I have added above snippet under post { } in jenkins pipeline.
• Basically idea is to shutdown the booted simulator always after execution irrespective of outcome i.e. pass or fail
• Thereafter I have not observe this issue again till date.

Happy Testing :)
