使用XCode 7.2錄製時XCUITest崩潰

我正在使用XCode 7.2試驗iOS的新UI測試框架。使用XCode 7.2錄製時XCUITest崩潰

我跟隨了一些教程，並觀看了來自Apple的演示視頻，並試圖記錄一些測試用例。當目標是「模擬器」時，第一次測試是成功的。當我嘗試在真正的設備中重複這些步驟時，XCode在啓動應用程序後立即崩潰。我使用Apple的iPhoneCoreDataRecipes演示應用程序開始使用簡單和「已驗證」的內容。

下面一個簡單的測試類：

#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]; 


}

它是一個已知的問題？有關如何調試問題的任何想法？我是否需要「以某種方式」啓用設備？

更新＃1

當我試圖在設備運行測試用例，我收到的Xcode的一些日誌。

看起來沒有任何反應，不執行測試用例時，Xcode嘗試加載應用程序，但黑屏

此外，當我試圖重新編碼的Xcode提供了以下崩潰：

IOS 8增強

iOS 8在Settings> Developer中包含一個新的Enable UI Automation首選項，允許第三方開發人員更好地控制其設備何時可用於執行自動化。對於物理iOS設備，默認情況下該設置處於關閉狀態，必須在執行任何UI自動化之前啓用該設置。在模擬器中，該設置默認啓用。

這在較爲明顯的要求外（ios9目標，10.10/11等），該文件還列出了其他一些要求，並鏈接你可能會發現有用的參考。
