appium: Unable to launch WebDriverAgent because of xcodebuild failure

Do I have the most recent component updates?

I use the most recent available driver/plugin and server versions

Is the component officially supported by the Appium team?

I have verified the component repository is present under the Appium organization in GitHub

Is there an existing issue for this?

I have searched the existing issues

Current Behavior

Mac OS: Sonoma 14.1.1 Appium Version: 2.2.2 XCode: 15.0.1

Build gets installed but then error occurring. Error while running the tests:

xcodebuild exited with code ‘70’ and signal ‘null’. WARN webdriver: Request failed with status 500 due to An unknown server-side error occurred while processing the command. Original error: Unable to launch WebDriverAgent because of xcodebuild failure: xcodebuild failed with code 70

ERROR webdriver: Request failed with status 500 due to unknown error: An unknown server-side error occurred while processing the command. Original error: Unable to launch WebDriverAgent because of xcodebuild failure: xcodebuild failed with code 70 [0-0] xcodebuild error message:

Expected Behavior

There should not be any error and it was working fine but after upgrading to Xcode we started seeing this webdriver error.

Minimal Reproducible Example

Error occurs outside of the test code

it looks like xcodebuild command by Apple found two simulator devices, that had iOS 16.2 while your capabilities specified iOS 17, thus the xcodebuild probably confused. You should specify the udid properly, or you may also drop specifying the udid so that Appium can create a new simulator instance with the iOS version
