I was working on my app and everything is fine, after i tried to export iPA for testing i got this error message as shown here:

I never seen anything like this error before, tried to clear flutter xCode builds and still same, i even can't install/update Cocoa pods, tried to remove podfile.lock to generate a new one and still same error can't do anything at all

Any idea what is this and how to fix it? Thanks!

So here is the solution,

I managed to fix it by delete & install the following files:

Before you start, make sure to check your Flutter Doctor flutter doctor -v and resolve any issues if available.

Steps:

• Open your Flutter project -> delete pubspec.lock

• Go to your main project folder -> open iOS folder -> delete both podfile podfile.lock

• Now open the terminal app (macOS)

• Copy & paste these command lines one by one and press enter after
each one:

1- gem list

2- sudo gem uninstall cocoapods (type Y and press enter if asked for confirmation)

3- sudo gem install cocoapods (this may take a while)

• Next, update and upgrade brew, press enter after each one:

1- brew update

2- brew upgrade

3- sudo gem update

• Last step, close your VS Code, Android Studio and re-open it, then open the built-in terminal and type flutter clean

Now press the Pub Get button and build your app, it should work.
