Flutter app not building on iOS simulator

I’m trying to start a Flutter project I have gotten on a iOS Simulator and the problem is I can’t. On another Mac, my friend was able to start it but I have been running in circles… I have tried:
**

  • Product > Clean Build Folder
  • deleted Pod folder and PodFile.lock and pod repo update – pod install
  • Erase all content and settings in the iOS Simulator
  • flutter clean, flutter pub get
  • inside the podfile :config.build_settings[‘IPHONEOS_DEPLOYMENT_TARGET’] = ‘15.0’ // or to any target for that matter
    Podfile:
# Uncomment this line to define a global platform for your project
platform :ios, '15.0'

# 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
  # pod 'FirebaseFirestore', :git => 'https://github.com/invertase/firestore-ios-sdk-frameworks.git', :tag => '10.3.0'
  use_frameworks!
  use_modular_headers!

  flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
end

post_install do |installer|
  installer.aggregate_targets.each do |target|
    target.xcconfigs.each do |variant, xcconfig|
      xcconfig_path = target.client_root + target.xcconfig_relative_path(variant)
      IO.write(xcconfig_path, IO.read(xcconfig_path).gsub("DT_TOOLCHAIN_DIR", "TOOLCHAIN_DIR"))
    end
  end
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
    target.build_configurations.each do |config|
      if config.base_configuration_reference.is_a? Xcodeproj::Project::Object::PBXFileReference
        xcconfig_path = config.base_configuration_reference.real_path
        IO.write(xcconfig_path, IO.read(xcconfig_path).gsub("DT_TOOLCHAIN_DIR", "TOOLCHAIN_DIR"))
      config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= [
        '$(inherited)',

        ## dart: PermissionGroup.calendar
        # 'PERMISSION_EVENTS=1',

        ## dart: PermissionGroup.reminders
        # 'PERMISSION_REMINDERS=1',

        ## dart: PermissionGroup.criticalAlerts
        # 'PERMISSION_CRITICAL_ALERTS=1'
      ]
      end
    end

    target.build_configurations.each do |config|
      config.build_settings['OTHER_SWIFT_FLAGS'] ||= ['$(inherited)']
      #config.build_settings['OTHER_SWIFT_FLAGS'] << '-D BYPASS_PERMISSION_NOTIFICATIONS'
      #config.build_settings['OTHER_SWIFT_FLAGS'] << '-D BYPASS_PERMISSION_IOSADDTOPHOTOLIBRARY'
      #config.build_settings['OTHER_SWIFT_FLAGS'] << '-D BYPASS_PERMISSION_IOSCHANGEPHOTOLIBRARY'
      end
  end
end

I have tried this in different orders and still no use. The errors (I haven’t put them all since they are huge) are:

etc...

I’m not sure what is the problem… Can the problem be the cocoapods or the PATHs ~/.zshrc files?

export PATH="/opt/homebrew/bin:$PATH"
export PATH="$PATH:/user/local/opt/flutter/bin"
export PATH="$PATH:$HOME/.pub-cache/bin"
export PATH="/opt/homebrew/Caskroom/flutter/3.22.2/flutter/bin:$PATH"

in the My flutter doctor -v is without issues. Any form of help is greatly needed and appreciated.

    I got the same error a few months ago, and I am trying to remove and reinstall Cocoapods and it works haha.
    From the error message, Have you been using any 3rd party packages?

    You can try to set the Deployment target for your Pods references with the following command:

    post_install do |installer|
 installer.pods_project.targets.each do |target|
  target.build_configurations.each do |config|
   config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '9.0'
  end
 end
end

    or remove the value:

    Code Block 
post_install do |installer|
 installer.pods_project.targets.each do |target|
  target.build_configurations.each do |config|
   config.build_settings.delete 'IPHONEOS_DEPLOYMENT_TARGET'
  end
 end
end

    Hopely this can help you to fix the issue 🙂

    I think main issue is this string from log:

    line 5: flutterfire: command not found

    Looks like your project uses firebase, which requires some additional configuration of your development environment. I recommend you to follow these instructions: https://firebase.google.com/docs/flutter/setup?platform=ios

    This particular issue with flutterfire can be resolved with this step

    Also, make sure that dart packages are in your path, here is documentation for this
