What is the easiest way to write code for an Xcode macOS App project that compares two files and discovers the differences like the FileMerge Developer Tool that comes with Xcode?
Is there an API for FileMerge or anything that does the same?
There is no ‘FileMerge’ API. However, you might be able to construct something out of Swift’s collection diffing support [1].
