Swift UI Testing Access string in the TextField

Question

I am using the UI Test Case class integrated in Xcode and XCTest to test app UI. I want to test something like this:

app = XCUIApplication()
let textField = app.textFields["Apple"]
textField.typeText("text_user_typed_in")
XCTAssertEqual(textField.text, "text_user_typed_in")

I've tried the textField.value as! String method; it does not work. I've also tried using the new async method with expectationForPredicate(), and it will result in a timeout.

Any idea how to do this or validation of this kind is not possible with UI Test and I could only write black-box tests?

I use this code and it works fine:

textField.typeText("value")
XCTAssertEqual(textField.value as! String, "value")

If you're doing something similar and it isn't functioning, I would check to make sure that your textField element actually exists:

XCTAssertTrue(textField.exists, "Text field doesn't exist")
textField.typeText("value")
XCTAssertEqual(textField.value as! String, "value", "Text field value is not correct")
