Swift version: 5.4
The NSDataDetector
class makes it easy to detect URLs inside a string using just a few lines of code. This example loops through all URLs in a string, printing each one out:
let input = "This is a test with the URL https://www.hackingwithswift.com to be detected."
let detector = try! NSDataDetector(types: NSTextCheckingResult.CheckingType.link.rawValue)
let matches = detector.matches(in: input, options: [], range: NSRange(location: 0, length: input.utf16.count))
for match in matches {
guard let range = Range(match.range, in: input) else { continue }
let url = input[range]
print(url)
}
