Failed to parse Target Device Version IOS Flutter build

[mrweiland]

If you are looking for help, please confirm the following...

• I confirm I have searched the Docs, Codemagic Sample Projects, and GitHub Discussions.
• I confirm the software versions on my local computer match the ones in CI environment (e.g. Xcode version, Gradle version). See here
• I confirm I am able to do a fresh clone of the repository and build the project on my local computer.

Which mobile framework are you using?

Flutter (Dart)

Steps to reproduce

I tried to see if there are some issues in podfile that version is not set but it seems fine.

Just run the build and i get the isssue - and its working fine on local computer and also i can archive and publish from xcode to testflight without any problem.

Expected results

Flutter build IOS and published to testflight.

Actual results

Hello @mrweiland
From the logs, you seem to be building in debug mode and since you mentioned you want to publish to the store, you might need to change to release in the build section of your Codemagic settings UI.
That aside, as regards the error in debug mode, a user with a similar error shared that they included the code below in their Podfile, and this was resolved in their case:

Post_install do |installer|
installer.pods_project.targets.each do |target|
flutter_additional_ios_build_settings(target)

# Forcefully set the deployment target for all targets
target.build_configurations.each do |config|
  config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '13.0'
end
end

Workaround for Xcode 14+ simulator build issues
installer.pods_project.build_configurations.each do |config|
config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64"
end
end

Can you please try this out on your end to see if this helps?
