我正在一个应用程序颤振中工作。安卓工作正常，但在 ios 中没有。我需要一些帮助才能在ios移动设备上运行它。我正在使用 lib：google_maps_flutter：^0.5.27+3和firebase_ml_vision：^0.9.3+8。Xcode 11.4.1 和 Mac os Catalina 10.15.4。有人知道如何解决这个问题。我还没有找到。

可能是在某些 XCode 项目文件上出现了错误，请尝试：
- 备份您的项目。
-
运行此命令
飘动清洁 &&\ rm ios/Podfile ios/Podfile.lock pubspec.lock && \ rm -rf ios/Pods ios/Runner.xcworkspace && \ 颤振运行
参考
在带有 m1 芯片的 mac 中，我无法在模拟器中运行我的项目，而是我不得不使用连接的物理 iPhone，它没有显示错误，运行良好。
此错误的关键部分可能是"ld：找不到体系结构x86_64符号"。似乎与处理器体系结构有关，因此请尝试导航到终端或 VS Code 中的项目文件夹，然后使用以下命令：
打开 iOS/Runner.xcworkspace
确保 iOS 部署目标正确。出于某种莫名其妙的原因，我的设置为iOS 11.0。我将其更改为iOS 16.0，它解决了问题。
在"项目"部分下更改为相应的iOS版本
在"目标"部分下也进行了更改
