在XCTestCase类访问的应用程序的委托对象导致misaligned_stack_error_迅

我试图在迅速进行单元测试。

我定义我的测试用例类是这样的：

import XCTest
import CoreData
import UIKit

class LazyLoadingCheckTests: XCTestCase {

    var appDelegate : AppDelegate = UIApplication.sharedApplication().delegate as AppDelegate

    override func setUp() {
        super.setUp()
        // Put setup code here. This method is called before the invocation of each test method in the class.
    }

    override func tearDown() {
        // Put teardown code here. This method is called after the invocation of each test method in the class.
        super.tearDown()
    }

    func testExample() {
        // This is an example of a functional test case.
        XCTAssert(true, "Pass")
    }
}

每当我试图执行一个测试用例，断点自动停在下面一行：

它显示以下堆栈跟踪：

当我尝试继续它显示了这一点：

任何线索？
