Locators not available after upgrade to iOS 11

Has anyone face issue of locators not available after upgrading from iOS 10.3 to iOS 11?

Driver.getPagesource () also does not find these elements.

Some more information

App is being built with Xcode 8, but Automation is using Xcode 9 to test on iOS 11.

What locators are you referring to?

Uploaded the driver.getPageSource results of on iOS 10 and iOS 11 device.

Below mentioned locator is not detected on iOS 11.

XCUIElementTypeImage type=“XCUIElementTypeImage” name=“Compose” label=“Compose New Message” enabled=“true” visible=“true” x=“323” y=“33” width=“34” height=“34”

Any pointers on what could be the possible reason, I have checked the issue with Appium 1.7.2 and iOS 11.2.6
