Ios 使用Xcode 7.2录制时，XUITest崩溃

我正在试验新的iOS用户界面测试框架，使用Xcode 7.2

我学习了一些教程，观看了苹果公司的演示视频，并试图录制一些测试案例。当目标是“模拟器”时，第一次测试成功。当我试图在一台真正的设备上重复这些步骤时，Xcode在启动应用程序后立即崩溃。我使用了苹果的演示应用程序，以便开始使用一些简单且“经过验证”的东西

下面是一个简单的测试类：

#import <XCTest/XCTest.h>

@interface RecipesUITests : XCTestCase

@end

@implementation RecipesUITests

- (void)setUp {
    [super setUp];

    // Put setup code here. This method is called before the invocation of each test method in the class.

    // In UI tests it is usually best to stop immediately when a failure occurs.
    self.continueAfterFailure = NO;
    // UI tests must launch the application that they test. Doing this in setup will make sure it happens for each test method.
    [[[XCUIApplication alloc] init] launch];

    // In UI tests it’s important to set the initial state - such as interface orientation - required for your tests before they run. The setUp method is a good place to do this.
}

- (void)tearDown {
    // Put teardown code here. This method is called after the invocation of each test method in the class.
    [super tearDown];
}

- (void)testExample {
    // Use recording to get started writing UI tests.
    // Use XCTAssert and related functions to verify your tests produce the correct results.


    XCUIApplication *app = [[XCUIApplication alloc] init];
    [app.navigationBars[@"Recipes"].buttons[@"Add"] tap];
    [app.textFields[@"Recipe Name"] typeText:@"Lef"];
    [app.navigationBars[@"Add Recipe"].buttons[@"Save"] tap];

    XCUIElementQuery *tablesQuery = app.tables;
    XCUIElement *descriptionTextField = tablesQuery.textFields[@"Description"];
    [descriptionTextField tap];
    //[descriptionTextField tap];
    //[descriptionTextField tap];

    XCUIElement *lefNavigationBar = app.navigationBars[@"Lef"];
    [lefNavigationBar.buttons[@"Edit"] tap];

    XCUIElement *overviewTextField = tablesQuery.textFields[@"Overview"];
    [overviewTextField tap];
    //[overviewTextField typeText:@"Lef2"];
    [lefNavigationBar.buttons[@"Done"] tap];
    [lefNavigationBar.buttons[@"Recipes"] tap];


}

#导入
@接口配方测试：XCTestCase
@结束
@实现菜谱测试
-（无效）设置{
[超级设置]；
//将设置代码放在这里。在调用类中的每个测试方法之前调用此方法。
//在UI测试中，通常最好在出现故障时立即停止。
self.continueAfterFailure=否；
//UI测试必须启动他们测试的应用程序。在安装程序中执行此操作将确保每个测试方法都会启动。
[[XCUIApplication alloc]init]launch]；
//在UI测试中，在测试运行之前设置测试所需的初始状态（如界面方向）非常重要。设置方法是一个很好的方法。

//使用录制开始编写UI测试。
//使用XCTAssert和相关函数验证测试是否产生正确的结果。
XCUIApplication*app=[[XCUIApplication alloc]init]；
[应用程序导航栏[@“食谱”]。按钮[@“添加”]点击]；
[app.textFields[@“Recipe Name”]typeText:@“Lef”]；
[应用程序导航栏[@“添加配方”]。按钮[@“保存”]点击]；
xguielementquery*tablesQuery=app.tables；
XUIElement*descriptionTextField=tablesQuery.textFields[@“Description”]；
[描述文本字段点击]；
//[描述文本字段点击]；
//[描述文本字段点击]；
XUIElement*lefNavigationBar=app.navigationBars[@“Lef”]；
[lefNavigationBar.按钮[@“编辑”]点击]；
XUIElement*overviewTextField=tablesQuery.textFields[@“概述”]；
[概览文本字段点击]；
//[概览文本字段类型文本：@“Lef2”]；
[lefNavigationBar.按钮[@“完成”]点击]；
[lefNavigationBar.按钮[@“食谱”]点击]；
}

这是一个已知的问题吗？你知道如何调试这个问题吗？我是否需要“以某种方式”启用设备

更新#1

当我试图在设备中运行测试用例时，我在Xcode中收到一些日志

看起来什么都没有发生，没有执行测试用例，Xcode试图加载应用程序，但它显示了一个黑屏

此外，当我试图重新编码Xcode时，会出现以下崩溃：
