    targets: [
        // Targets are the basic building blocks of a package. A target can define a module or a test suite.
        // Targets can depend on other targets in this package, and on products in packages which this package depends on.

Applying Patches

import JSONPatch

let sourceData = Data("""
                      {"foo": "bar"}
let patchData = Data("""
                     [{"op": "add", "path": "/baz", "value": "qux"}]

let patch = try! JSONPatch(data: patchData)
let patched = try! patch.apply(to: sourceData)

Generating Patches

import JSONPatch

let sourceData = Data("""
                      {"foo": "bar"}
let targetData = Data("""
                      {"foo": "bar", "baz": "qux"}
let patch = try! JSONPatch(source: sourceData, target: targetData)
let patchData = try!
