崩溃原因如下：
Terminating app due to uncaught exception ‘NSInternalInconsistencyException‘, reason: ‘Could not load NIB in bundle: ‘NSBundle </Users/taylor/Library/Developer/CoreSimulator/Devices/E65C4959-4F43-44C4-A245-30DC389DAF97/data/Containers/Bundle/Application/95BD4ACE-5864-44DB-A084-1DAEE22B4951/******.app> (loaded)‘ with name ‘Main‘‘
解决方案：修改Main Interface 为Main
