flutter build ios Error (Xcode): unsupported option '-G' for target 'arm64-apple-ios10.0'

Failed to build iOS app

Could not build the precompiled application for the device.

Error (Xcode): unsupported option '-G' for target 'arm64-apple-ios10.0'

Error launching application on iPhoneSE.

solution:

markchiu@MacPro ios % pod update

Update all pods

Updating local specs repositories

CocoaPods 1.15.0 is available.

To update use: `gem install cocoapods`

For more information, see https://blog.cocoapods.org and the CHANGELOG for this version at https://github.com/CocoaPods/CocoaPods/releases/tag/1.15.0

step 1: 試著更新cocopods.

sudo gem install cocoapods

after that, you need to update pod using below command

pod setup

You can check pod version using below command

pod --version

step2: 再參考這一片文章：

https://github.com/firebase/flutterfire/issues/13342

把

You have to go to Xcode => Runner => Build Settings and put "Allow Non-modular Includes In Framework Modules" to "yes"

第三步：增加 if target.name == 'BoringSSL-GRPC'...相關code在 Podfile

post_install do |installer|
  installer.pods_project.targets.each do |target|
           

           //other code may in there.

          if target.name == 'BoringSSL-GRPC'
                target.source_build_phase.files.each do |file|
                  if file.settings && file.settings['COMPILER_FLAGS']
                    flags = file.settings['COMPILER_FLAGS'].split
                    flags.reject! { |flag| flag == '-GCC_WARN_INHIBIT_ALL_WARNINGS' }
                    file.settings['COMPILER_FLAGS'] = flags.join(' ')
                  end
                end
            end

  end
