今天升级xcode14.0

问题1:
Could not build the precompiled application for the device.
Swift Compiler Error (Xcode): Stored properties cannot be marked potentially unavailable with '@available'
/Volumes/xxx/myshared/opt/fvm/versions/3.3.1/.pub-cache/hosted/pub.flutter-io.cn/flutter_inappwebview-5.4.3+7/ios/Classes/Types/UserScript.swift:12:5

方法1：

方法2:

修改Podfile

主要是这1行：
platform :ios, '14.0'

下面这行没雕用：
config.build_settings['SWIFT_VERSION'] = '5.0'

platform :ios, '14.0'

//省略
post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)

    target.build_configurations.each do |config|
      config.build_settings.delete 'IPHONEOS_DEPLOYMENT_TARGET'
      config.build_settings['SWIFT_VERSION'] = '5.0'
      config.build_settings['ENABLE_BITCODE'] = 'NO'
      config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= [
        '$(inherited)',
        'AUDIO_SESSION_MICROPHONE=0',
        'DISABLE_PUSH_NOTIFICATIONS=1'
      ]
    end
  end
end

最终方法：

以上就只能最低支持IOS14上运行了

回到报错原因：

Stored properties cannot be marked potentially unavailable with '@available'

修改pubspec.yaml替换仓库地址：

dependency_overrides:
  flutter_inappwebview:
    git:
      url: https://github.com/CodeEagle/flutter_inappwebview

将1、2操作的修改回到iOS11.0

platform :ios, '11.0'

OK 重新编译运行，没啥问题。
