34505268: XCUIElement TextField value returns placeholderValue

[openradar-mirror]

Description

Summary:
In Xcode 9, the value of a TextField XCUIElement is returning the placeholderValue when the text field is empty. This is different from Xcode 8, where value was empty.

Steps to Reproduce:
In my app code, I am setting the attributedPlaceholder property on my UITextField instance.

In my UI test, this should pass:
let textField = XCUIApplication().textFields["address_line_1"]
let stringValue = textField.value as? String ?? ""
XCTAssertTrue(stringValue.isEmpty) // FAILS

Expected Results:
value of a TextField element should be the user-entered value, not the placeholder value.

Actual Results:
value is the same as placeholderValue when no text has been entered by the user.

Version/Build:
Xcode 9 GM -- Version 9.0 (9A235)

Configuration:
Running in "iPhone SE" simulator

Product Version: Version 9.0 (9A235)
