I cannot run or build the iOS app. This always happens with the same error.

  • I have already repaired Flutter pub caches.
  • Deleted the pod files.
  • Removed the iOS folder and tried:
Launching lib/main.dart on iPhone 12 Pro Max in debug mode...
Running pod install...
Running Xcode build...

# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# In Android, build-name is used as versionName while build-number used as versionCode.

i have the same issue before a thou days and in mycase the solution was to countinue this steps:

  1. Backup Runner folder
  2. Delete the ios folder
  3. Go to a terminal and execute flutter create . in the flutter project folder
  4. Paste your Runner folder back into the ios folder
  5. pod deintegrate in the ios folder
  6. pod install also in the ios folder
  7. flutter clean in the flutter project folder
  8. flutter pub get
  9. flutter run

Please note that if you use firebase you need to re-insert the GoogleService-Info.plist file

Hope it helps!
