我正在使用VSCode来开发我的Flutter应用，但在升级XCode到最新版本（14.3）后，无法在模拟器（iOS 15，iPhone 11）上运行Flutter应用。以下是错误消息：

错误（Xcode）：链接器命令失败，退出代码为1（使用-v查看调用）

安装了 14.3 后，我不得不修改我的 ios/Podfile 以再次运行我的项目：

问题是，iOS 的部署目标必须为 11.0 或更高版本，以适配 iOS 16.4。

查看：https://developer.apple.com/forums/thread/725300

更新：如 @danielrosero 所提到的，您需要在编辑 iOS/Podfile 后再次运行 pod install。

After installing 14.3 I had to modify my `ios/Podfile` to get my project running again:

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

installer.generated_projects.each do |project|
project.targets.each do |target|
target.build_configurations.each do |config|
config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '11.0'
end
end
end
end

The issue is that, the deployment targets for iOS must be 11.0 or higher for iOS 16.4.

See: https://developer.apple.com/forums/thread/725300

UPDATE: As mentioned by @danielrosero, you need to run `pod install` again, after editing `iOS/Podfile`.

I have updated the Pods libraries Minimum Deployments 11.0

Make sure all the library Minimum Deployments Versions should be above 11.0, Then it worked for me.

OR

Add the below code in the end of the Podfile and do pod install.

&lt;!-- begin snippet: js hide: false console: true babel: false --&gt;

&lt;!-- language: lang-html --&gt;

post_install do |installer|
  installer.generated_projects.each do |project|
    project.targets.each do |target|
        target.build_configurations.each do |config|
            config.build_settings[&#39;IPHONEOS_DEPLOYMENT_TARGET&#39;] = &#39;11.0&#39;
         end
    end
  end
end

&lt;!-- end snippet --&gt;

Sure, here are the translated instructions:

**步骤 1**

跟踪由库引起的问题。如果您看一下屏幕截图，我在FMDB Pod上遇到了一个错误：

**步骤 2**

我们需要更改受影响的Pod文件上的iOS版本，因为新的Xcode不支持iOS 11.0以下版本。

**步骤 3**
额外步骤：在更新Pod后，您可能会遇到构建分发错误。为避免此问题，请执行以下操作。

更改目标Pod的分发设置。

重新在Xcode上构建您的应用程序。

Extra Step you may also face a build distribution error after updating pods. Do this to avoid that issue.

Change Distribution setting on Target Pod.
