Find Unused Classes in the Current Directory
fui find
The find command lists all the files that contain unused imports and exits with the number of files found.
Find Unused Classes in any Path
fui --path=~/source/project/Name find
Skip Interface Builder (.xib) Files
Running fui with -x (or --ignore-xib-files) will, for example, mark Foo.h as unused when Foo.xib holds a reference to the Foo class and no other references to Foo.h exist.
fui -x --path=~/source/project/Name find
Ignore Local Imports
Running fui with -l (or --ignore-local-imports) will, for example, mark Foo.h as unused when Bar.h contains a local (quotation syntax) import of Foo.h (eg. #import Foo.h).
fui -l --path=~/source/project/Name find
Ignore Global Imports
Running fui with -g (or --ignore-global-imports) will, for example, mark Foo.h as unused when Bar.h contains a global (bracket syntax) import of Foo.h (eg. #import <Framework/Foo.h>).
fui -g --path=~/source/project/Name find
Ignore a Path
Running fui with -i (or --ignore-path) will, for example, ignore a Pods folder when searching for headers or referencing files.
fui --path=~/source/project/Name --ignore-path=Pods find
Ignore Multiple Paths
Running fui with -i (or --ignore-path) can ignore multiple folders when searching for headers or referencing files.
fui --path=~/source/project/Name --ignore-path=Pods --ignore-path=Libraries find
Delete All Unused Class Files with Prompt
fui --path=~/source/project/Name delete --perform --prompt
