flutter run 

Could not build the precompiled application for the device.

Error launching application on iPhone 

修复：从 master 分支升级 flutter，删除 podfile.lock 并重新运行 pod install

临时的修复：

来自 GitHub 的解决方法 1：

使用 sudo 和您最喜欢的文本编辑器：

open /Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS17.0.sdk/System/Library/Frameworks/WebKit.framework/Headers/WKWebsiteDataStore.h,

将__IPHONE_OS_VERSION_MAX_ALLOWED从170000更改为180000

解决方法 2：

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

解决方法 3 更新

CocoaPods

gem install cocoapods 

并运行：

flutter clean 

flutter upgrade

cd ios && pod repo update

flutter run 

并且该项目必须构建没有问题

将 flutter_inappwebview 更新到 5.8.0 对我有用。

我是这样决定的：

1. 删除Pods和Podfile.lock文件

2. 删除pubspec.lock文件

3. Flutter clean && pub get

4. cd ios

5. arch -x86_64 pod install

6. 再次运行项目
