A Swift wrapper around JsDiff.

Carthage is currently the only supported installation method:

github "nerdishbynature/JSDiff.swift"

Simply put your desired colors into the JSDiff initializer where deletedColor is the lighter color and deletedWordColor is the one that should be more prominent (see the example image).

This method will result a JSLineDiff which has 2 attributed strings containing the diff.

let oldLine = "... something"
let newLine = "..."

let jsDiff = JSDiff(deletedColor: UIColor.deletedColor(), deletedWordColor: UIColor.strongDeletedColor(), addedColor: UIColor.addedColor(), addedWordColor: UIColor.strongAddedColor())

let result = jsDiff.diffWords(oldLine, newLine: newLine)
oldLineLabel.attributedText = result.oldLine
newLineLabel.attributedText = result.newLine
