Unable to start WebDriverAgent session because of xcodebuild failure

Issues/Bugs
1

I am using Appium to run my tests against real iPad Safari.
The setup works fine and the tests are running fine.
But after a few hours, Appium breaks at a step where it takes a screenshot.

I restart Appium after every test suite (which is around 30 mins)
So, usually there is no problem upto 10 suites. But after that it breaks at a step where it take the screenshot.
And it doesnt get started properly after that for some time.

Below are the logs when Appium is restarted after the screenshot broke.
(BTW, I do not see any error in the logs when Appium breaks when the screenshot is taken.)

Any help would be highly appreciated!

Detailed logs attached.

Hello,
Have you tried the below desired capability (IOSMobileCapabilityType):
caps.setCapability(USE_PREBUILT_WDA, true);

It won’t try to build WebDriverAgent on each run, instead it will use the one’s that already installed on the first step.

Hope it helps.
Cheers!

I have the same problem with the version 1.10.0.
The tests start and run for some time and then breaks at some point of time.

After that, all the tests fail with the following error:
