Hi Sireesha,
Sorry,previously I did not copy the whole path variables you mentioned and only provided partial variable ; so only got that issue persisted. After I copied the whole path variables,the issue is gone.

I have installed Xcode and command line tools to but now got different issues.

Hi Sireesha,
Thank you for the help so far,the solution you suggested has worked.
Now I think there is a problem with my JAVA code .

The code is installing WebDriverAgent,then launching the app some attempt.
Other attempt its not launching the app ,only launching the WebDriverAgent app.
Other attempT eclipse CRASHES.

please let me k=know if I am doing anything wrong.

	service = AppiumDriverLocalService.buildService(new AppiumServiceBuilder().usingAnyFreePort());
	service.start();
	DesiredCapabilities capabilities=DesiredCapabilities.ipad();
	
	capabilities.setCapability(MobileCapabilityType.AUTOMATION_NAME, "XCUITest");

	driver= new IOSDriver<IOSElement>(service.getUrl(),capabilities);
	
	driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
	service.stop();

Below are the logs.

Hi Sireesha,
I was able to do the step 1 and 3 but not the step 2.
For step 2, I went to '/usr/local/lib/node_modules/appium/node_modules/appium-xcuitest-driver' but unable to find the Scripts folder inside it.

FYI,the code is working for the first time.But for the next time it is telling that "the address is in use". So I tried to kill it using the command you gave (also I need to kill my app and WebDriverAgent app from iOS device),it is working fine after that.

The above things are working only for some 10 times.Post that I need to restart my iOS device to make it work. Then it is posting me the below logs.

"[debug] [WebDriverAgent] Device: Dec 7 19:49:12 Rafis-iPad XCTRunner[249] : Enqueue Failure: UI Testing Failure - Unable to update application state promptly. 0 1

[debug] [WebDriverAgent] Device: Dec 7 19:50:27 Rafis-iPad XCTRunner[249] : Enqueue Failure: UI Testing Failure - App state of (null) is still unknown 0 1"
===============
Is there any other way I can release the address using JAVA code instead of doing this manually every time?

Currently I am just using service.stop(); at the end of code every time.

Thank you in advance.

Hi Sireesha,
I followed all the above mentioned and it is working properly in happy flow.
But it case the program was stopped in middle or an exception occurred, then the next time onwards there are multiple issue coming through.
The 'port is in use' issue has been resolved by the command 'lsof -P | grep ':8100' | awk '{print $2}' | xargs kill -9
'.

But the other prevailing issue is,'WebDriverAgent' app in the physical device opens and hangs there. It never goes to background and opens my app. I even tried uninstalling WebDriverAgent still no use.I need to restart the device in order to resolve this issue.

Any solution for this??

I think below is the corresponding log.
