Defining URLs using String literals in Swift
Almost every URL out there is constructed using a string, while the Foundation provides a very convenient way to construct a URL from a string using URL(string:) still we can add some sugar to make it even easier to use!
extension URL: ExpressibleByStringLiteral {
public init(stringLiteral value: String) {
guard value.representingValidURL, let url = URL(string: "\(value)") else {
fatalError("\(value) cannot be mapped to a url")
}
self = url
}
}
private extension String {
var representingValidURL: Bool {
let detector = try? NSDataDetector(types: NSTextCheckingResult.CheckingType.link.rawValue)
if let match = detector?.firstMatch(in: self, options: [], range: NSRange(location: 0, length: self.utf16.count)) {
return match.range.length == self.utf16.count
} else {
return false
}
}
}
// You can use it as follows
let url: URL = "https://www.alihilal.com"
let task = URLSession.shared.dataTask(with: url)
