Xcode 9 beta不喜欢.xib文件的文件名中的“~ipad”.选择新的构建系统时(对于项目,即使用旧构建系统成功编译),它会出错：
unable to build node:
‘/Users/dev/Library/Developer/Xcode/DerivedData/proj-aiatvieseyfwjkfqncikqcohpdsn/Build/Products/Debug-iphoneos/proj.app/Controller~ipad.nib’
(node is produced by multiple commands; e.g.,
‘adf8a93da84709e14beaf35ec6d6d21c02c34dc4669b6bd1e18a027ff75b53b5:CompileXIB
/Users/dev/git/proj/Resources/Controllers/Controller.xib’ and
