file too small (length=0) file

Xcode链接真机运行后报错:

 file too small (length=0) file '/Users/xxxx/Library/Developer/Xcode/DerivedData/App-eelvbkglixbbxdfqteypnueqfvdl/Build/Intermediates.noindex/App.build/Debug-iphoneos/App.build/Objects-normal/arm64/SocketIOClient.o' for architecture arm64

解决:

1.选择xcode菜单的Product下的Clean,或者组合键是Cmd+Shift+K,清除一遍
2.重新编译
