Xcode 6.2的调试器似乎没有从我的应用程序中崩溃。每当它崩溃时，我只会得到一个弹出窗口，上面写着：
恢复与“Agile Lab的iPhone 6 Plus”的连接并运行“Tag Beta“再次，或者如果”Tag Beta“仍在运行，您可以附加到它 通过选择Debug＆gt;附加到流程＆gt;标签测试版。
我有断点和“所有异常”的断点。当我去Window＆gt;设备并按“查看设备日志”显示：

现在，如果我在生产模式下运行应用程序并附加Fabric，它会正确捕获异常：

虽然Fabric能够解决这个问题很好，但如果调试器能够捕获异常会更有帮助，所以我可以看到值，堆栈跟踪等等。是否有一些设置我只是不知道是否已经或者这是Xcode的问题？
