install nodejs, then run command in terminal
Xcode -> Project -> Build Settings -> Write LinkMap File -> YES，
Set "Path to Link Map File" to where you want to create LinkMap file, Default in "~/Library/Developer/Xcode/DerivedData/XXX-eumsvrzbvgfofvbfsoqokmjprvuh/Build/Intermediates/XXX.build/Debug-iphoneos/XXX.build/"
Xcode -> Build

node linkmap_ext.js filepath -u
-h: format size
-l: stat libs
-u: stat unused class
filePath refers to the path of the link map file.

node linkmap_ext.js /Users/xxx/Downloads/script/linkMap.txt -u
linkmap_ext command can help you find out the unimport files, if you want to find unused import files use below command

WSSampleModule.h
NSString+Additions.h
WSSampleTestViewController.h
These files is imported in LTSampleViewController, but may not used in this file.
Note that some files you may use, like 'NSString+Additions.h', so be careful when you delete it
