Welcome to Selenops, a Swift Web Crawler.

Given a webpage url and a word to search, Selenops will look for said word in that page, and all pages linked in there, recursively.

Usage

import Selenops

// Initialize crawler.
let crawler = Crawler(
  startURL: URL(string: "https://fivestars.blog/")!,
  maximumPagesToVisit: 10,
  wordToSearch: "Swift" // Specify the word to search here.
)

// Set delegate.
crawler.delegate = ... // Needs to conform to CrawlerDelegate

// Start crawling!
crawler.start()

The crawler delegate will get information such as visited webpages, and in which webpages the specified word has been found.
