If you would like to konw the detail algorithem, read the paper which proposes GumTree.
You can easily check AST-based differences.
The green means Insert, the red means Delete, the yellow means Update, and the purple means Move.

Usage:
$ ./.build/release/SwiftyGumCLI <src> <dst>
Arguments:
src - Source file (orifinal file)
dst - Destination file (editted file)
Options:
--report [default: cli] - Report format of EditScript
--min-height [default: 1] - Minimum height that AST nodes are matched in TopDown Matching
--sim-border [default: 0.2] - The boundary value that determins two different node should be matched.
Add the following to your .gitconfig.
[diff]
tool = SwiftyGum
[difftool "SwiftyGum"]
cmd = <The path of the executable on your system)> $LOCAL $REMOTE
[difftool]
prompt = false
You can execute SwiftyGum for edited swift files in your repository.
