[Problem]

Error (Xcode): type argument 'nw_proxy_config_t' (aka 'struct nw_proxy_config *') is neither an Objective-C object nor a block type /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator17.0.sdk/System/Library/Frameworks/WebKit.framework/Headers/WKWebsiteDataStore.h:119:46 Parse Issue (Xcode): Could not build module 'WebKit' /Users/build/ios/Debug-iphonesimulator/flutter_inappwebview/flutter_inappwebview.framework/Headers/flutter_inappwebview-Swift.h:893:8 Uncategorized (Xcode): Command SwiftEmitModule failed with a nonzero exit code

 

[Solution]

ios/podfile의 하단에 아래의 코드를 추가한다

post_integrate do |installer|
  compiler_flags_key = 'COMPILER_FLAGS'
  project_path = 'Pods/Pods.xcodeproj'

  project = Xcodeproj::Project.open(project_path)
  project.targets.each do |target|
    target.build_phases.each do |build_phase|
      if build_phase.is_a?(Xcodeproj::Project::Object::PBXSourcesBuildPhase)
        build_phase.files.each do |file|
          if !file.settings.nil? && file.settings.key?(compiler_flags_key)
            compiler_flags = file.settings[compiler_flags_key]
            file.settings[compiler_flags_key] = compiler_flags.gsub(/-DOS_OBJECT_USE_OBJC=0\s*/, '')
          end
        end
      end
    end
  end
  project.save()
end
