Flutter: error Xcode: command PhaseScriptExecution failed with a nonzero exit code

I tried to run flutter after updating to the newest stable version

Error output from Xcode build:
↳
    ** BUILD FAILED **


Xcodes output:

Could not build the application for the simulator.
Error launching application on iPhone 13 Pro.

I've tried flutter clean and flutter pub get but that isn't the fix. Anyone any idea how to fix this?

Solution

As i see you are currently using flutter 2.5.2 which is newest,So Update you flutter SDK by running command

flutter upgrade

Then Upgrade the current package's dependencies to latest versions by running command

flutter pub upgrade

Go to iOS folder of the project run

pod init

and

pod install

I hope this solution solve your problem.
