bundle exec fastlane beta

it shows this error:

Reset to default

I tried everything I could do, but I ended up re-creating ios directory.

My 2 projects had the same settings, but only 1 project made this issue.

Anyway, this is what I did finally.

rm -rf ios flutter create -i swift .

Of course, it's very annoying to reset flavors and other things.

Note: by performing the above steps will lose all native ios setup. In my case I was getting this error in the demo project I did this.

this worked! make sure to have the -i swift flag.
Does not work, says project-name is not a valid Dart package name.
Did you reset the flavors and other things manually, or just restore the old workspace project files?
I've just hit this problem randomly after adding a Share Extension to the project, but I can't face deleting the ios folder - it has so many customisations I don't think I can face recreating them all! But... I can't get past this problem either.
@theLastNightTrain im in the exact same situation as you, one 18 months later. Did you ever managed to figure out how to fix this issue?

Answer of Mr. @sunken.shim is great, although there are few steps if there is error

Error: project-name is not a valid Dart package

You can follow the steps

  1. Enter the codes as Mr.sunken.shim stated.
  2. Execute : rm -rf ios
  3. Execute : flutter create -i swift myproject
  4. Copy the ios folder from the new swift folder created.
  5. Paste it in project folder.
  6. You are good to go.
