ios - XCUIElement#typeText 对于两个文本字段失败

Question

我在 Xcode 11.1 上观察到 XCUITest 的奇怪行为。我只有一个带有两个 UITextField 的 Storyboard，两个 UITextField 都带有可访问性标识符集。我想在两者中输入文本:

    class ExampleUITests: XCTestCase {  

        func testTypingInTextField() {  
            let app = XCUIApplication()  
            app.launch()  

            let field1 = app.textFields["Field1"]  
            field1.tap()  
            field1.typeText("foo")  

            let field2 = app.textFields["Field2"]  
            field2.tap()  
            field2.typeText("bar")  
        }  

    }  

在第二个字段中键入内容失败，并出现以下错误，并且光标在第二个文本字段中闪烁:

      }  
      ︎Find: Descendants matching type TextField  
        Output: {  
          TextField, {{10.0, 30.0}, {355.0, 34.0}}, label: 'Field1', value: foo  
          TextField, {{10.0, 72.0}, {355.0, 34.0}}, label: 'Field2'  
        }  
        ︎Find: Elements matching predicate '"Field2" IN identifiers'  
          Output: {  
            TextField, {{10.0, 72.0}, {355.0, 34.0}}, label: 'Field2'  
          }  

如果我删除在 field1 中输入的代码，它就可以工作。

我上传了example project here

我在这里想念什么？

模拟器中的“硬件»删除所有内容和设置”修复了问题。可能是 Beta 版留下的一些东西。
