重现步骤

在测试XCode 16 Beta 1和iOS 18模拟器时。

  1. 遵循以下步骤将Flutter模块添加到iOS应用中:https://docs.flutter.dev/add-to-app/ios/project-setup(我们使用了选项A-使用CocoaPods和Flutter SDK嵌入)
  2. 使用XCODE Beta 16.0运行iOS应用-iOS 18模拟器

预期结果

应用程序运行无错误,我们怀疑这可能与IOS 18模拟器出现错误有关,但我们不确定。

实际结果

两者都显示以下错误:
稳定频道,3.22.2,
主频道,3.23.0-13.0.pre.218

这个错误也发生在通过运行flutter createflutter run创建基本的Flutter应用时,以及在使用这些版本和这个Flutter doctor运行Wonderous app(https://github.com/gskinnerTeam/flutter-wonderous-app.git)时:
