Cannot access an iOS app element using xpath

[Maria Machlowska]

The problem in topic, I am trying to acces an iOS application's element using xpath.
Appium log:
debug: Appium request initiated at /wd/hub/session/ff4f1220-d4ea-4c0a-ad2c-704c6bc03b86/element

When I try to acces the same element by name, everything works fine.

We are currently working to provide full xpath support, stay tuned. Not sure what's hapening in you case, can you send me the xpath you used, I can only see the escaped version in the log

I am really glad, that it is possible to fix the problem with xpath.

The xpath to element I am using in the example above is:
    $xpath = "//button[@name='Add']";
  $this->driver->findElement(WebDriverBy::xpath($xpath));
  $this->driver->click();

For now you could probably get around it with this

    $elementName = "Add";
  $this->driver->findElement(WebDriverBy::name($elementName));
  $this->driver->click(); 

And yes, I will fix that issue in xpath.
