The “Swift Language Version” (SWIFT_VERSION) build setting must be set to a supported value for targets which use Swift.

Hello,

Just added the plugin and got this error The “Swift Language Version” (SWIFT_VERSION) build setting must be set to a supported value for targets which use Swift. This setting can be set in the build settings editor. Which Swift version should also be used?

I forget which one of these fixed the issue for me, but you can try the following: You also may need to run flutter clean and may also need to de-integrate the podfile and reinstall the pods. Sorry for the lack of specificity but one of these should do the trick!

1. add use_frameworks!

   
   target 'Runner' do
   use_frameworks!

2. pre_install

pre_install do |installer|

workaround for https://github.com/CocoaPods/CocoaPods/issues/3289

Pod::Installer::Xcode::TargetValidator.send(:define_method, :verify_no_static_framework_transitive_dependencies) {}

end

3. post_install

post_install do |installer| installer.pods_project.targets.each do |target| target.build_configurations.each do |config| config.build_settings['ENABLE_BITCODE'] = 'NO' config.build_settings['SWIFT_VERSION'] = '3.2' end

workaround for https://github.com/CocoaPods/CocoaPods/issues/7463

    target.headers_build_phase.files.each do |file|
        file.settings = { 'ATTRIBUTES' => ['Public'] }
    end
end

end

I finally updated the plugin. It should fix this issue. Let me know if it does.

@alamboley could you open an issue in flutter's repo regarding plugins that use swift? I think this might be an issue they could fix.
