flutter build ipa - Command PhaseScriptExecution failed with a nonzero exit code

Question

I am using flutter and trying to build an ipa file, I am able to run my app my device or simulator no problem, but can't build an ipa file. I am using the flutter command flutter build ipa and I get this error:

Command PhaseScriptExecution failed with a nonzero exit code

I have tried to do the following:

flutter clean
flutter pub get
cd ios
pod install
pod update

Here is my Podfile:

platform :ios, '11.0'

# CocoaPods analytics sends network stats synchronously affecting flutter build latency.
ENV['COCOAPODS_DISABLE_STATS'] = 'true'

project 'Runner', {
  'Debug' => :debug,
  'Profile' => :release,
  'Release' => :release,
}

def flutter_root
  generated_xcode_build_settings_path = File.expand_path(File.join('..', 'Flutter', 'Generated.xcconfig'), __FILE__)
  unless File.exist?(generated_xcode_build_settings_path)
    raise "#{generated_xcode_build_settings_path} must exist. If you're running pod install manually, make sure flutter pub get is executed first"
  end

  File.foreach(generated_xcode_build_settings_path) do |line|
    matches = line.match(/FLUTTER_ROOT\=(.*)/)
    return matches[1].strip if matches
  end
  raise "FLUTTER_ROOT not found in #{generated_xcode_build_settings_path}. Try deleting Generated.xcconfig, then run flutter pub get"
end

require File.expand_path(File.join('packages', 'flutter_tools', 'bin', 'podhelper'), flutter_root)

flutter_ios_podfile_setup

target 'Runner' do
  use_frameworks!
  use_modular_headers!

  flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
  pod 'DKImagePickerController/PhotoGallery', :git => 'https://github.com/miguelpruivo/DKImagePickerController.git'
end

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
  end
end

And here is my pubspec.yaml file:

Can anyone tell me what I am doing wrong?

Answer 1

Update your SDK version from flutter upgrade version 3.0.2 to 3.0.3.

export PATH="your_path/flutter/bin:$PATH" 
flutter clean
flutter pub get
cd ios
sudo gem pod install
pod install
run the app from Android Studio IDE so that it checks all the necessary installs.
flutter build ipa --release -t lib/main.dart 

Hope it may help you.

Answer 2

You can check the below steps:

1. Go to iOs Folder and delete podlock file and pods folder
2. Go to the pod file and edit the below section that contains like as below code:

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
    target.build_configurations.each do |config|
      config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '13.0'
     end
  end
end

3. Go to terminal and cd to iOS folder and run "pod cache clean --all" command
4. run pod install(pod update) command

Try to Archive again with XCode IDE
