[iOS] Linker error: 'Undefined symbols for architecture arm64' about flutter_flipperkit

[kiplelive-zariman]

Here the solution worked for me

1. declare all flavour on this section

project 'Runner', {
  'Debug' => :debug,
  'Profile' => :release,
  'Release' => :release,
  
  # Declare all flavaor/variant here
  'Debug-Development' => :debug,
  'Release-Development' => :release,
  'Release-Staging' => :release,
  'Release-Production' => :release,
}

2. remove

use_modular_headers!

3. $static_framework should be declare same level with post_install, not inside project 'Runner'

$static_framework = ['FlipperKit', 'Flipper', 'Flipper-Folly',
  'CocoaAsyncSocket', 'ComponentKit', 'Flipper-DoubleConversion',
  'Flipper-Glog', 'Flipper-PeerTalk', 'Flipper-RSocket', 'Yoga', 'YogaKit',
  'CocoaLibEvent', 'OpenSSL-Universal', 'boost-for-react-native']
pre_install do |installer|
  Pod::Installer::Xcode::TargetValidator.send(:define_method, :verify_no_static_framework_transitive_dependencies) {}
  installer.pod_targets.each do |pod|
      if $static_framework.include?(pod.name)
        def pod.build_type;
          Pod::BuildType.static_library
        end
      end
    end
end

post_install do |installer|

Finally the Podfile should look like this

# Uncomment this line to define a global platform for your project
platform :ios, '9.0'

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

project 'Runner', {
  'Debug' => :debug,
  'Profile' => :release,
  'Release' => :release,
  # Declare all flavaor/variant here
  'Debug-Development' => :debug,
  'Release-Development' => :release,
  'Release-Staging' => :release,
  'Release-Production' => :release,
}

  generated_xcode_build_settings_path = File.expand_path(File.join('..', 'Flutter', 'Generated.xcconfig'), __FILE__)

    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

  raise "FLUTTER_ROOT not found in #{generated_xcode_build_settings_path}. Try deleting Generated.xcconfig, then run flutter pub get"

@amorenew Can you try to remove use_modular_headers! on the Podfile?

[arcturus]

Got the same error in 1.17.3 (updated from 1.12.13+hotfix.9)

[mikaoelitiana]

Did you find a solution for this?

[obiwanzenobi]

Got the same error in 1.20.3

[amorenew]

@lijy91 I wonder if you could check what is wrong with multi schemes?

I got it in a Flavored project "Multi Schemes- White label"

Sample of the multi scheme project:
https://github.com/amorenew/flutter-flavor-example

Error:

Undefined symbols for architecture x86_64:

You can try this step

Open ios/Runner.xcworkspace Add a empty Swift file (e.g Runner-Noop.swift) into Runner Group And make sure the Runner-Bridging-Header.h file is created.

[amorenew]

@lijy91 I will try it

[amorenew]

@lijy91 Adding Runner-Noop.swift didn't resolve my case

[amorenew]

@lijy91 still not working, I wonder is my sample building on your machine?

[rzubascu]

@amorenew I have the same issue when archiving the iOS app. Did you find any fix for this?

[lijy91]

@rzubascu Please remove it in release mode.
