Crystal Reports 2008 - фильтр с несколькими предопределенными значениями

Вы можете использовать URLComponents, чтобы избежать необходимости вручную уклониться от строки запроса:

let scheme = "https"
let host = "www.google.com"
let path = "/search"
let queryItem = URLQueryItem(name: "q", value: "Formula One")


var urlComponents = URLComponents()
urlComponents.scheme = scheme
urlComponents.host = host
urlComponents.path = path
urlComponents.queryItems = [queryItem]

if let url = urlComponents.url {
    print(url)   // "https://www.google.com/search?q=Formula%20One"
}

extension URLComponents {
    init(scheme: String, host: String, path: String, queryItems: [URLQueryItem]) {
        self.init()
        self.scheme = scheme
        self.host = host
        self.path = path
        self.queryItems = queryItems
    }
}

if let url = URLComponents(scheme: "https",
                             host: "www.google.com",
                             path: "/search",
                       queryItems: [URLQueryItem(name: "q", value: "Formula One")]).url {

    print(url)  // https://www.google.com/search?q=Formula%20One
}
