Чтобы закодировать URL-адрес в Xcode, вы можете использовать различные методы. Вот несколько вариантов:

1. Использование addingPercentEncoding(withAllowedCharacters:):

   if let encodedString = originalString.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed) {
      // Use the encodedString
   }

2. Использование URLComponents:

   if var urlComponents = URLComponents(string: originalString) {
      urlComponents.percentEncodedQuery = urlComponents.percentEncodedQuery?.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)
      if let encodedString = urlComponents.string {
          // Use the encodedString
      }
   }

3. Использование CFURLCreateStringByAddingPercentEscapes(Objective-C):

   NSString *encodedString = (__bridge_transfer NSString *)CFURLCreateStringByAddingPercentEscapes(
                                  NULL,
                                  (__bridge CFStringRef)originalString,
                                  NULL,
                                  CFSTR("!*'();:@&=+$,/?%#[]"),
                                  kCFStringEncodingUTF8);
   // Use the encodedString

4. Использование stringByAddingPercentEncodingWithAllowedCharacters(Objective-C):

   NSCharacterSet *allowedCharacters = [NSCharacterSet URLQueryAllowedCharacterSet];
   NSString *encodedString = [originalString stringByAddingPercentEncodingWithAllowedCharacters:allowedCharacters];
   // Use the encodedString
