更新到Xcode10后,XCUITest的测试目标似乎无法正常工作

我从Xcode 9.4更新到xcode 10,然后在尝试运行我的UI测试时似乎没有任何工作.虽然构建在测试之前成功完成,但测试应用程序加载了一段时间然后测试失败.并且源代码也成功构建,我可以在模拟器上运行应用程序.

错误是:

Early unexpected exit, operation never finished bootstrapping - no restart will be attempted. (Underlying error: The test runner failed to load the test bundle. Executable cannot be loaded for some other reason, such as a problem with a library it depends on or a code signature/entitlements mismatch.))
