Accessing child application in container

Issues/Bugs
1

I am automating an app inside a container app on a physical iOS device. Both container and child applications are hybrid. I cannot get the appium server to click on an element in the child application. I tried switching window handles but that didn’t help. Any thoughts?

                     String context=wd.getContext();
		
		System.out.print(context); 

		for (String winHandle : wd.getWindowHandles()) {
	         
			 System.out.println("Handle is " + winHandle);
			 
		 
			 try{   
				 
				 
				 wd.findElementByXPath("//*[@id='xyz']").click();
					
					
				    //TouchActions touchAction = new TouchActions(wd);
					//touchAction.singleTap(sft).build().perform(); 
			         }
			         catch(NoSuchElementException e){
			        	 System.out.println(e.getMessage());
			        	 continue;
			         }
			 
			 
            wd.switchTo().window(winHandle); // switch focus of WebDriver to the next found window handle (that's your newly opened window)
            checkPageIsReady(wd);
          
         
		}	
		
		
	}

}

Here’s a sample console output for an iteration:

WEBVIEW_14Handle is 14
