Error (Xcode): Undefined symbol: _swift

Hi.
Yesterday I tried creating custom YoutubePlayer widget.
Since flutterflow has its own widget, which is using YouTube_player_iframe, I did not add any custom dependencies - just used custom widget.
After successful deployment at 3:03PM, I made some tweaks in the custom widget code and since then I can’t deploy successfully - even if I restore to snapshots before the successful deployment.

Test mode works completely normal.


import 'package:flutter/material.dart';
import 'package:youtube_player_iframe/youtube_player_iframe.dart';

// NAJPROSTSZA FUNKCJA DART DO EKSTRAKCJI ID (OPARTA NA SPLIT/SUBSTRING)
String? extractYoutubeId(String url) {
  String trimmedUrl = url.trim();
  
  // 1. Obsługa pełnego linku: https://www.youtube.com/watch?v=ID_FILMU
  if (trimmedUrl.contains('watch?v=')) {
    // Rozdzielamy na dwie części i bierzemy wszystko po '?v='
    String id = trimmedUrl.split('watch?v=')[1]; 
    
    // Usuwamy wszelkie dodatkowe parametry (&list=...)
    if (id.contains('&')) {
      id = id.substring(0, id.indexOf('&'));
    }
    return id.length == 11 ? id : null;
  } 
  
  // 2. Obsługa skróconego linku: https://youtu.be/ID_FILMU
  else if (trimmedUrl.contains('youtu.be/')) {
    // Rozdzielamy URL po 'youtu.be/' i bierzemy drugą część
    String id = trimmedUrl.split('youtu.be/')[1];
    
    // Usuwamy wszelkie dodatkowe parametry
    if (id.contains('?')) {
      id = id.substring(0, id.indexOf('?'));
    }
    return id.length == 11 ? id : null;
  }
  
  // 3. Obsługa ID (jeśli podano sam ID)
  else if (trimmedUrl.length == 11) {
    return trimmedUrl;
  }

  // Zwracamy null dla nieznanych lub nieprawidłowych formatów
  return null;
}
