I was so excited to upgrade to XCode8 trying to run tests with iOS 10 but then found out XCode8 no longer supports automation instruments. So I accepted the fact that I need to wait for Appium’s official upgrade to run tests on iOS10 .
But what happened after I downgraded to Xcode 7.3.1 really puzzled me. I kept getting this error even on the iOS8/9 devices which were ok before the XCode8 upgrade: “WebDriverException: An unknown server-side error occurred while processing the command. Original error: Removing {appId} failed”. Why is this happening even I am now back to XCode 7.3.1? I tried everything I can think of including removing/reinstalling ideviceinstaller.
To give more info here are my Developer Settings:
–session-override --full-reset --native-instruments-lib --default-capabilities “{“newCommandTimeout”: “7200”}”
The error is related to --full-reset. However removing that from the setting is triggering another error:
[debug] [iOS] App is not installed. Will try to install.
[MJSONWP] Encountered internal error running command: Error: Installing {path to the app} failed

There must be something that was not correctly reverted after the downgrade to XCode7.3.1. Looks like some residue from the removed XCode 8 that broke everything.
Anyone has a resolution?
Thanks!
